Please feel free to suggest locations and goals for future events. A UCSC Mapping Party is a "next" good choice, as OSM needs added and improved additional footpaths as well as amenities like bicycle parking and drinking fountains. A good meeting place is Café Iveta at Quarry Plaza, as it is centrally-located, and serves delicious food and beverages.
UCSC Professor of Computer Engineering user:manduchi proposed McHenry Library for a Mapping Party. However, the professor and venue seem to be unavailable for this function in the near future. Professor Manduchi and his Computer Engineering 80A students did not contribute to OSM around Santa Cruz during Fall quarter of 2015, but did in earlier academic quarters. This class may once again make contributions in future academic quarters.
Who's up for organizing another mapping party?
Fading into the past, there is a not-actually-active "Cake Map" for UCSC where you might feel free to be inspired. No longer is it a realistic option to take ownership of a slice if you can and will improve it: simply improve the map at UCSC!
Santa_Cruz_Mapping_Party Wilder Ranch State Park (May 2019)
University of California Santa Cruz (UCSC) Professor of Environmental Studies Millard-Ball used OSM at UCSC Winter 2016 in his ENVS 196 class to audit the pedestrian network on campus and use it as a model for improvements, including longer-term planning with the Campus Architect.

In late 2009, user:srmixter (nmixter) imported official landuse=* zones from the Santa Cruz County GIS (SCCGIS) site. (But not without significant problems!) See Santa_Cruz_County,_California/Archive.
These (multi)polygons were intended to be a "first draft" of landuse and greatly benefit by continuing improvement and additional micro-mapping with finer detail than data which were originally entered in 2009. They are updated as necessary with newer data from here or real world experiences. Importantly, in no way are these data intended to interfere with newer, better, more detailed data being added to the map. Wholesale removal of the SCCGIS data without such improvement is regressive to OSM's overall data content, so contributors are encouraged to UPDATE, ADD and IMPROVE data here, where as superior data supersede SCCGIS data, the older data can be removed. As superior data are added or existing data derived from SCCGIS (multi)polygons become so heavily modified that they are unrecognizable from their original source, tags identifying their source should be removed. This allows editors to know which data came from SCCGIS (those with, say, Zoning tags) and those which don't (no such tags). Slowly taking place now, eventually, these SCCGIS "first draft" landuse (multi)polygons are replaced by superior data. Please feel free to edit such data with NEWER, ADDITIONAL or IMPROVED data; remove SCCGIS tags from (multi)polygons as they become so modified that they no longer resemble the original data.

Landuse area data inside of city limits (cities of Santa Cruz, Capitola, Scotts Valley, Watsonville) derive from sources other than SCCGIS (which is county only) or have been directly experienced. See specific "City of..." sections below. There is an encouraging trend, for example in the Prospect Heights neighborhood of Santa Cruz (a "neighborhood, fully zoned residential" as a large polygon): smaller, much more accurate polygons tagged landuse=residential have begun to be added, excluding streets, sidewalks, and other not-strictly-residential areas in the "fully zoned" polygon. While this continues, when the "enclosing" residential is fully populated, the landuse=residential tag on the enclosing polygon can be removed. However, the enclosing polygon remains useful, to "name" the neighborhood. When that occurs, add a place=neighborhood tag. This is consistent with the original intent of "capturing zoning with landuse (is a good first step)...then replacing these with (more precise data) correctly supplement them."
Santa Cruz has won a Gold Star Award from BestOfOSM.org, one of only a few places in North America to have achieved this accolade. The site notes that OSM (mapnik/Standard) displays "nearly perfect landuse!"
OSM strives to include both the latest official data and OSM-contributed data which are superior. Sources of official data include SCCGIS Zoning.zip v6 down to v1, CPAD 2018a (CPAD v2) and CPAD 2016a (CPAD v1). The latest versions of these official data "somewhat" agree. There are edits local to OSM which include "editor smear" of a meter or so, usually caused by copying a (multi)polygon in one layer of JOSM and pasting in another. A fact: official data do improve with multiple iterations (especially as OSM, SCCGIS and CPAD/GreenInfo data "watch each other" over the longer-term).
In 2009, user:Apo42 uploaded some of the open space conservation and/or recreational areas and all California State Park entities (from UC Davis-sourced CaSIL data) including those in Santa Cruz County. The vast remainder of the parks in the county (county, city and private) came from the SCCGIS Landuse import (see Landuse above). A small number of minor, usually city parks (e.g. La Barranca, Mimi De Marta) were added manually from non-SCCGIS sources.
During March, 2017, a modest amount of data were conflated (with existing SCCGIS v3 landuse data) from California Protected Areas Database (CPAD). (CPAD generally "winning" over minor boundary differences, although the county's western edge at Big Basin State Park diverges substantially between existing CPAD data and SCCGIS data; areas from Whitehouse Canyon to Waddell Creek continue to challenge). These data are tagged source=California Protected Areas Database (CPAD) – www.calands.org (December 2016), the v1 of these data. This manual conflation of units and super-units was difficult: minor discrepancies between SCCGIS landuse and CPAD data, especially alignment in west and south county, were noticed and called to the attention of the next data update (as Carto rendering completed with the v1 upload). What we call "CPAD version 2" data began with CPAD "2018a" data. Sometimes tags from the shapefile in ALL CAPITAL LETTERS were left in the data when they do not logically map well to OSM tags. Where objectionable, these can be deleted.
In early 2019, these newer (2018a) v2 CPAD data were discovered and compared with SCCGIS Zoning.zip v5 data (noted in Landuse above). In March 2019, email correspondence among CPAD's publisher (GreenInfo Network) and SCCGIS attempted to determine which data defining components of Big Basin State Park are "more correct" (notably, West Waddell Creek Wilderness / WWCW segments along the western edge of the Santa Cruz County boundary), as there are v5 discrepancies of as much as 30 meters westerly and 90 meters northerly. According to GreenInfo Network, "we consider State Parks' data authoritative when mapping state parks specifically. Our standard generally is to refer to agency data but use parcels as a geometry base. But with State Parks specifically we tend to defer to their boundaries over parcels." A reply from SCCGIS says "the answer depends on your mapping needs" and "there are a number of other factors potentially at play here as well. For instance, we've known for a long time that in certain areas of the county parcels can be off by up to 300'. This is acknowledged in the disclaimer we put on our internet mapping applications." The result is that park data near Little Basin west to about Last Chance Road seem more accurate as SCCGIS publish them, which are "winning" in OSM there, while west of there, along the San Mateo County boundary in and near WWCW, CPAD data seem to "better align" with multiple other data sources (and so remain in OSM, even as they differ from SCCGIS data). See also "County Boundary" (below), where some easterly drift (15 - 20 meters) is seen in SCCGIS County Boundary data near Big Basin Way compared to USGS topos and other sources. See also recent (2019-Q2) Talk page Discussion on park:type=* tagging (being deprecated, but widely extant here).
user:DanHomerick imported the Stream.shp layer of the Hydrography dataset from the Santa Cruz GIS site in October 2009. He used the Java program shp-to-osm-0.6.1 to convert the data from Shapefile format to OSM format and bulk_upload.py to upload it. Since, at the time of the import, shp-to-osm does not connect line segments he used the Validator plugin in JOSM to merge overlapping nodes. This connected many stream segments correctly, but left some unconnected at import time. Existing rivers were not programatically deleted, instead preferring to rely on manual verification before their deletion. Many imported streams were initially pointing the wrong direction (a way with a stream/river tag should point downstream). Work is underway to correct issues with the import: corrections to wrong-direction waterways are mostly complete as of Feb. 2010. However, as of May 2014, JOSM's Validator plugin reports many unconnected stream endpoints where they conjoin other streams. A note about the tags used: many of the streams were listed as type "swale" (a low lying area) in the original dataset. These were translated as waterway=stream + intermittent=yes + note=swale for the upload, but in many cases, especially near the mouth of a stream, a swale may not actually have intermittent flow. As intermittent=yes now appears to affect the Mapnik rendering (with a dashed light blue line), the tag should be deleted where it is inaccurate.
In early 2010 user:Apo42 uploaded CaSIL-based county-boundary data for all of California, including Santa Cruz County. The Santa Cruz County boundary was harmonized by user:stevea. In particular, the southern boundary displayed centuries of flooding and re-coursing of the Pajaro River, the eastern boundary is close to, but not quite exact with the SCCGIS landuse=* upload, especially around Mt. Madonna Park, the northern boundary was checked against stream data uploaded by user:DanHomerick (noted above) and user:mk408's stream data upload from Santa Clara Valley Water District along the "spine" of differing flow directions at ridgetops of the Santa Cruz Mountains, and the northwest and western boundaries were checked against both CaSIL state park and SCCGIS landuse=* uploads, still not quite with perfect alignment. An error in the northwestern county line near Gazos Creek Road was found in the data from the CPAD import in March, 2017, this was harmonized with data from the USGS topographic data of the area.
In early 2018, user:stevea remapped the county boundary based on SCCGIS' October 27, 2017 "County Boundary.zip" shapefile data. This was harmonized with the shared boundaries of Santa Clara, San Mateo, Monterey and San Benito Counties. In 2019, this was done again with SCCGIS' 2/9/2019 updated data, however, there is some noticeable drift with USGS topos, Santa Clara County data and CPAD. These were "best guessed" and almost certainly contain minor errors (as much as 15 - 20 meters in places).
Santa Cruz County has an excellent network of established and developing bicycle infrastructure. The Santa Cruz County Regional Transportation Commission (SCCRTC) publishes a (paper and online) County Bike Map (CBM) displaying these bicycle lanes, paths and alternate routes, the latest version in September, 2016. Also, SCCGIS publishes (click "Data" then "Transportation") a transportation layer that includes the County's electronically published bicycle infrastructure. JOSM can be persuaded (with the opendata plugin) to open the shapefile data's .shp entry point resulting from unzipping this file. While every single way in the CBM denoted with colors has had tags applied in OSM (green bicycle path = highway=cycleway or cycleway=track, red bicycle lane = cycleway=lane, purple bicycle alternate = bicycle=yes) — OSM bicycle infrastructure tagging — and these have been collected into route=bicycle relations tagged with network=lcn — OSM bicycle route tagging — there are also ways in the County which (according to signage or roadway paint in the real world) also have these tags, but are not (usually) collected into route=bicycle relations, as they are not so denoted in the CBM. Some of these ways are included as CycleNet "Z" routes, see below.
In 2010, a proposal was made to SCCRTC to superimpose upon the CBM's local-government-published infrastructure a local cycleway network (network=lcn) numbering protocol, colloquially known as CycleNet (or "CycleNetSZ" in a statewide Caltrans context). The routes and their numbering largely have a one-to-one correspondence with the physical bicycle infrastructure published in the CBM, ideally, the bicycle infrastructure resulting from downloading SCCGIS' latest bicycle shapefile data noted above. CycleNet is simply a set of logical routes proposed as a local network numbering protocol superimposed on this published physical infrastructure. In introductory stages as it is brought before jurisdictions for discussion and approval, two initial routes (Walnut-Soquel, which might become lcn or rcn 8, and Freedom Blvd., which might become lcn or rcn 80) were introduced into OSM as proposed network=rcn bicycle route relations. Additionally, other network=lcn route relations (with state=proposed) have also been introduced, with network=lcn and route=mtb (the latter only for mountain bike routes suffixed with "M" in their ref=* tag). Thus, OSM is a venue for geographic communication/visualization of lcn/rcn/mtb bicycle route discussions and public introductions into a numbered local network. A set of tags to render mountain bike routes as both orange lines (in Cycle Map / OpenCycleMap layer) shown from route=mtb, as well as giving them dark blue numbers in the (shared with network=lcn) local address space have been determined, thanks to research via renderers OpenCycleMap (OCM) and Waymarked Trails' (WMT) Cycling and MTB layers. As local jurisdictions approve these now-proposed routes, state=proposed shall be removed to denote any newly local/legally-sanctioned numbering. Signage on these routes may follow their state going from proposed to approved, so cyclists should not expect physical route (number) signs on these until jurisdictions approve them. However, MUTCD D1-3a / D1-3c signage (named bicycle destinations, distances in miles, turn direction arrows), without CycleNet or any other numbering protocol route numbers, began to appear in 2019 around Santa Cruz.
An exception to "no bike route signage" is Pacific Coast Bike Route (PCBR), signed by California's DOT, Caltrans. (Most or all of Oregon-to-Mexico PCBR will become network=ncn and ref=95 should Caltrans apply for and AASHTO approve USBR 95, believed to be in planning in 2019). This (public) PCBR should not be confused with the (private) route of the same name by Adventure Cycling Association (ACA); entered in OSM is Caltrans' public PCBR, not ACA's private PCBR. OCM and WMT's Cycling layer display California's PCBR as "PCB" where known, including Santa Cruz County. PCBR is concurrent with CycleNet 95/95N/95S as network=lcn routes, though logically network=rcn seems better — 95 is "regional" in the sense proposed rcn 8 and 80 are regional, as 8, 80 and 95 act as a "spine" of regional County bicycle connectivity. (As of 2019 with MBSST opening its first segment, "M40" is also network=rcn here; see below). However, after erecting PCBR signs, Caltrans ceded route definition to local authorities (counties and cities). It has been confirmed that de facto "on the ground" Caltrans PCBR signs contradict the de jure route asserted by the City of Santa Cruz. The explanation offered (by the City, in city limits) was "Caltrans gave us the authority to change PCBR and we did, though we haven't changed the signs yet." The PCBR that the City asserts appears to be identical to the ACA's PCBR, which OSM does not have permission to enter, as the City says "here is our PCBR." Yet the City's declaration puts this PCBR segment into the public domain, so it is entered into OSM (in the City). Hopefully this explains PCB route/PCBR signage discrepancies in the City of Santa Cruz.
Additions to CycleNet's "one-to-one correspondence" noted above (not displayed by CBM) are Z-suffixed routes: CycleNet has several such "connectors." In the real world, Z-routes are signed with "Share The Road" or "Bicycles May Use Full Lane," painted with sharrows (all three are cycleway=shared_lane) or are otherwise legal bicycle infrastructure (bicycle=yes). Though bike-legal, CBM does not display these (as purple bicycle=yes), so CycleNet denotes them as Z routes: bike-legal infrastructure collected into sensible "connector routes." Major Z routes are 5Z (Highway 9), 25Z (Empire Grade), 26Z (Highway 236) and the 826 route group (826 Gazos Creek Road, 826M through Big Basin and 826Z China Grade), all challenging for cyclists (steep, narrow, sinuous, non-M routes are shared with automobile traffic). CycleNet 826 from/to Hwy 1 (via 26Z and 5Z at Saratoga Gap connecting to Santa Clara County's lcn=13, a route from San Jose to Saratoga and Saratoga Gap) could become a part mountain bike network=rcn (regional) route linking multiple counties, from San José to the Pacific Ocean.
As the Monterey Bay Sanctuary Scenic Trail (MBSST) multi-use "Rail Trail" is in early phases of construction, CycleNet denotes as 40Z MBSST's "planning route" and various segments as they are constructed are known in CycleNet as 40A, 40B...up to 40Y. As of 2019-Q2, MBSST Construction Segment #1 (was CycleNet 40I Boardwalk) is completed in the real world and entered into OSM tagged ref=M40, as MBSST is a de facto route in the cycle_network=US:CA:SZ namespace, though not yet de jure in the cycle_network=US:CA:SZ:CycleNet namespace. ref=M40 solves how to label both route designations (MBSST = CycleNet 40) with a single tag. (If CycleNet becomes de jure, MBSST may become ref=40 when completed). The new bike-and-ped-only bridge across the mouth of the San Lorenzo River is also assumed to be part of the (relatively unknown / poorly geographically specified) California Coastal Trail (bike and ped), assigned as CycleNet 30. As the bridge is bicycle=dismount (walk bikes), this segment is also tagged (via a relation separate from MBSST) ref=30P, the "P" suffix in CycleNet meaning "pedestrian only" (or on a bicycle, dismount and walk your bike).
In 2009, we began a convention with parks, starting with user:Apo42's tagging of State Park data that included park:type=state_park. In Santa Cruz County (and elsewhere afterwards), this was extended to include park:type=county_park and park:type=city_park for parks with management/jurisdiction at those admin_levels (there were explorations to combine these tags with admin_level=* at some point) and park:type=private_park to private parks (for example, a small decathlon-event park with access=private), private campgrounds and for-fee short-term trailer parks. The point was not to make these render (yet) but such tags are useful in a search query, for example. A proto-proposal (park_level=*, see park:type=*) to combine these tags with boundary=* so these render with different color dashing was developed but never more widely submitted to the OSM community; the plan was for rendering to be extended to display parks tagged with state_park, county_park, city_park and private_park using different colors of dashing. (Today, boundary=national_park renders in mapnik with green dashes, and it is a partial/wide OSM convention that this tag is appropriate on state parks). However, see this Discussion, which offers a proposal to begin to deprecate park:type=* in preference of more modern, widely accepted and better documented park tagging standards. Included in those is a newer tagging scheme boundary=protected_area, utilizing protection_title=* and protect_class=* keys (which themselves are not very developed with regard to rendering) which may be applicable to many park-like areas now denoted park. Progress on this transition has already begun here, for example this used to be tagged leisure=park, but is now more accurately tagged boundary=protected_area.
As noted in the Santa_Cruz_County,_California/Archive, because the county is 2/3 wooded, many landuse=special_use polygons from early SCCGIS imports were tagged natural=wood. This tag is NOT used in its usual way at UCSC, so the campus renders with its preferred light-yellow amenity=university tag. Being simultaneously a university yet also heavily wooded with redwood trees, local OSM convention assumes UCSC is "already" wooded, "except where it is not." For contrast, the Campus Natural Reserve polygons ARE explicitly set to natural=wood and Lower Moore Creek and Cave Gulch/Wilder even have some landuse=meadow on top of these. So, UCSC (the amenity=university polygon) is "assumed to be wooded, unless tagged otherwise" (such as natural=grassland, grassy areas not grazed by cattle, landuse=meadow, grassy areas which are grazed by cattle, amenity=parking, building=university, building=dormitory, highway=*, etc. Landuse and landcover are frequent topics of confusion in OSM, hence this explicit convention here. The "all wooded" areas around the intersection of UCSC (amenity=university), Pogonip Open Space Preserve (leisure=nature_reserve) and Henry Cowell Redwoods State Park (boundary=national_park) illustrates this well: the boundaries are apparent and readily identifiable with their landuse, even as the landcover on all three in the real world is identical (densely wooded). A newer trend is not to double-tag (on leisure and natural) to more explicitly define natural=wood, so wood was deleted from both Pogonip leisure=nature_reserve and HCRSP relations and added to other specifically-wooded relations (members may have differing leaf_type values). This is also done on state parks in the county, where, for example, the Forest of Nisene Marks State Park and Big Basin Redwoods State Park have both had their leisure=park tag removed (correctly) and "largely wooded, similar state-park-shaped multipolygons" were added to OSM to reflect landcover in those areas. So, now included in the map are both landuse=* or boundary=* polygons (the state park) and landcovers upon them (largely natural=wood, with some "punch out" polygons of natural=grassland or perhaps geological=outcrop as inner members). This transition of breaking apart "assumed to be wooded" polygons (splitting apart polygons with a "stacked" natural=wood tag) is a work in progress, user:doug_sfba is active with landcover north of the Santa Cruz / Santa Clara County line (the "spine" of the Santa Cruz Mountains) and user:stevea is active south of there, to around the San Benito County line. Now (2019-Q4) complete is the deprecation of leisure=park on state parks in the county, though this tag does (believed correctly) remain on county parks and especially city / urban parks.
Work to be done in the County
Many TIGER-sourced roads in rural, unincorporated Santa Cruz County were entered with or continue to have errors of up to tens of meters. Some are better expressed as highway=unclassified or are actually highway=track (or highway=service + service=driveway) instead of TIGER's default of highway=residential. Additional tags like barrier=gate and access=private are also missing in many locations. Most of these roads are public, some are access=private (it is not always clear which), so it would be very helpful for those with local knowledge of (and access to) these rural roads to gather GPS wanderings and better classify, align and tag them (highway=*, access=*, name=*...). Due to heavy tree cover, this is more true in heavily-wooded, hilly/mountainous areas of central and northern County, and less true in flat, largely treeless, primarily agricultural areas of southern County. This displays how complete we are at reviewing data from the TIGER import: as of 2019, substantially reviewed, but minor TIGER Review is still required, especially in more difficult-to-access areas. (That ITOworld renderer is now unsupported, other renderings of TIGER-completeness-visualizers are being explored).
Certain "holes" in county (zoning or) landuse=* uploads remain from polygons tagged "special_use" or "public_facility:" SCCGIS punted on specifically defining what landuse=* these were, so "special_use" conveys "less defined." As previously described, mostly- or all-wooded parcels are frequently also tagged natural=wood, perhaps with meadows/grassland and buildings superimposed. This worked well for a decade or longer, though newer distinctions among "park," "wood," "forest," "scrub," "grassland," and (especially among already) "landuse" are being better mapped. Also, some otherwise "blank" public_facility polygons (no rendered OSM landuse=* value) need a site visit to determine what they actually are (e.g., landuse=industrial as a water_tower facility). Two notable "public_facility" polygons are significant portions of state highway corridors (State Routes 1 and 17).
As it attached from SCCGIS' declaration of "Park" in its 2009 "Zoning.pdf" file, revealing its use as both vague and flexible, what was long-ago tagged leisure=park captured many private, sometimes spiritual/religious conference grounds and broadly speaking, natural-state, largely unimproved contemplative and meditative spaces. When private (often as religious communities), these are similar to parks in a broad sense, as they are sometimes permissively open to respectful public uses such as hiking. One emergence of 2009's SCCGIS Zoning (landuse=*) import was to better categorize these "Park" entities: sometimes both leisure=park and amenity=place_of_worship turned out to accurately capture landuse semantics at these areas. (For example, Quaker Center west of Ben Lomond, Land of Medicine Buddha near Aptos, Jikoji at the northern tip of the county and Vajrapani Institute at the north end of Kings Creek Road). As sometimes difficult exploration of more remote areas continues, the number of parks with unknown names continues to decrease. A believed-more-correct OSM tagging trend began in Fall 2014: tag name=Unknown Park applied from the SCCGIS Zoning (landuse=*) upload has been converted to tag name:absent=yes. As of February, 2016, there remain dozens of parks tagged name:absent=yes which still need accurate naming, either from a site visit (if signs exist) or further querying of County or State records. Some of these appear to be public properties which are planned to be improved into parks in the future, but remain closed/no access until then. The March, 2017 CPAD conflation improved a fair number of these parks and "protected areas" with better name=* tags. Here is an Overpass Turbo query to display these. In 2018 and 2019, some of the religious-oriented areas were more-consistently tagged with amenity=place_of_worship and perhaps landuse=recreation_ground if they are open to public recreation uses (such as Mount Hermon's Redwood Canopy Tours and Sequoia Aerial Adventure), removing leisure=park tags.
A California Public Records Act request of UCSC building footprint data is partially complete, thanks to release of the data by UCSC's Privacy and Information Practices Director. Work to migrate these from .dwg to .osm took place: while there was partial progress and partial failure, UCSC is willing to produce a .shp shapefile as an intermediate, another migration path to get these into OSM. Two of us (software-heavy engineering professionals) have tried .dwf via Teigha to shapefile (various methods and tweaks, the GRASS 6.3 "v.in.dxf, v.out.ogr" method documented in our wiki, others...) to no avail. If you have knowledge how to achieve this data workflow (.dwg -> .shp or .dwg -> .osm, whether via .dxf or not), please OSM missive stevea.
Around upper Happy Valley, north and west of Laurel Glen and Mountain View, an edge between landuse and landcover ("treed farmland") blurred due to some confused editing. This has largely "healed" with the SCCGIS v4 landuse update. In late spring 2018 the v3 data were reverted with a note=*, asking users to check OSM's definition of landuse=farmland. Some of these areas have landuse=vineyard, landuse=orchard and landuse=greenhouse_horticulture overlays, and while they both are and appear (from aerial imagery) to be largely "treed" it is correct to call these areas farmland, as whether they do allow tree harvesting or not, consistent with their landuse, they continue to generate vineyards/wineries, orchards and greenhouses, all prevalent in this county (even as 2/3 of it remains covered by trees). The county zoning here is "RA" meaning "residential/agricultural," or a "live-on (family) farm," something which OSM doesn't have strictly accurate tagging for, so a choice is made between landuse=farmland and landuse=residential, not ideal, but better than nothing. From personal experience, these Happy Valley "farms" are extremely diverse agricultural areas: in addition to wine grapes, tree fruit and hothouse crops, they generate wildcrafted herbs for aromatherapy, rare mushrooms by foraging at the tree bases, apiaries / beekeeping and other beneficial insect hatching (such as ladybugs to control aphid infestation), etc. All of these are "agricultural landuse" on areas which appear to be "somewhat treed" (though no or few timber permits prevent Zoning=TP for Timber Production from being tagged, where then the landuse=forest tag is applied) AND with residences where the owners live and raise these "crops." (Important to remember: "farmland" doesn't ONLY mean row crops). Along with continuing discussion between "landuse" and "landcover" in OSM, "this is complex." This wiki's Discussion page is a good place to discuss these issues locally. A similar "healing" with v5 data occurred in 2019-Q1 with residential and wooded areas in Brookdale, Boulder Creek and other areas in the county: a correct trend is to "break apart" both of these (landuse=residential and natural=wood) rather than "stacking" them into one (multi)polygon.
The two major components of bus and rail which display in the Transport Layer merit specific mention, due to their partially incomplete state in OSM (though modernization and completion quite handsomely continue now!):
• Santa Cruz Metropolitan Transit District (SCMTD) provides substantial bus service to many parts of the county. Moderate but incomplete highway=bus_stop data are entered into OSM, initially around the University of California campus, extending citywide in 2013 and early 2014. Also entered is inter-county bus route "Highway 17 Express," linking to San José's Diridon Station for CalTrain and Amtrak rail connections (plus BART and High Speed Rail in the future). This route is nearing "going green" to PublicTransit v2 standards partially thanks to geofabrik's OSM Inspector tool. A semi-automated system (SCMTD's quarterly-released GTFS protocol data) to transform routes and stops into route relation data in OSM is under development. Otherwise the tedious work of entering these routes and updating them quarterly must be (and is, slowly but surely) completed manually. Manual entry began with most University-Downtown routes in February 2014. All stops and additional "alternate segments" of these routes may not yet be complete. As of late 2014, the SCMTD bus route network being entered into OSM is in progress, perhaps 55% - 60% complete. SCMTD routes remaining to be entered into OSM could use re-assesement here and now. Additional volunteers assistance is appreciated! As of late 2019, there has been substantial growth towards fully realized Public Transport version 2 public_transport elements and relations. Hooray!
• Since late 2012, Santa Cruz Branch rail is in public ownership (administered by SCCRTC). While light industrial/freight usage (lumber, frozen foods, biodiesel matter) continues on the southern five miles of track around Watsonville, longer-term planning is underway to offer future passenger rail service on most of this line. Sites, stations, halts and platforms which displayed in OSM as proposed rail stops came from studies as early as 1998, these are obsolete. As new and potentially different rail infrastructure and services emerged, proposed and actual rail features were updated in OSM. In early 2014, SCCRTC was awarded a Caltrans Transit Planning grant to undertake an analysis of commuter and intercity passenger rail service, studying recommendations for phased, efficient service on the branch: objectives included comparisons of cost-effective options to provide additional transportation options. In 2014-Q4, results were published and in early 2015 updating of railway=stations, railway=tram_stops and railway=halts was completed in OSM. As of 2016-Q1, County rail infrastructure in OSM has stabilized, as additional improvements (sidings, signal infrastructure, speed limit and control point data...) continue to be updated (these "minor infrastructure" elements remain incomplete). OpenRailwayMap displays rail infrastructure and OpenPublicTransportMap displays passenger rail. An early-2019 CTC status update is seen here, select March 13 2019 Pt 2 at 38:16. Finally, there is much railway=abandoned in the county (e.g. in the San Lorenzo Valley) not yet entered into OSM; ODbL-compliant data sources for these historical rail routes (or their entry) are appreciated.
City of Santa Cruz
The COSCZoning.kmz file from http://gis.cityofsantacruz.com/kml was used to "officialize" commercial districts, industrial zones and residential neighborhoods (among other areas, like parks and schools) of the City of Santa Cruz. While exactly correct for parks, schools, commercial and industrial zones, this file contains an overabundance of data for residential areas, such as distinctions between low- and medium-density zoning. Hence, these residential polygons were coalesced where necessary to build the named (and numbered, put into ref=*) neighborhood areas shown at the City web site. These display at closer zoom levels, out to z=14. The place=suburb nodes (Downtown, Westside, Eastside, Seabright and UCSC, displaying at medium zoom levels, out to z=12) and place=locality nodes (Midtown, Terrace Hill, Terrace Point, East Morrissey and Science Hill) emerged with local consensus, they appear to have stabilized.
Work continues (2019 onwards) in the City of Santa Cruz to add and complete the following:
• better lanes=* tagging and turn restriction relations,
• tags for disabled access routing: many more areas which are well-served for wheelchairs or low-vision persons (disabled parking spaces, highway=elevator, automatic_door=yes, ramp:wheelchair=yes, kerb=lowered, tactile_paving=yes, traffic_signals:sound=yes...) are not marked as such nor are mapped with these access nodes or routes in mind where they certainly exist,
• better and more consistent address numbering at landmark buildings and block level starting Downtown (a major tourism attraction, popular with locals too!),
• completion of UCSC campus (specifically, remaining highway=footways and highway=steps remain incomplete -- see The Cake). Also remaining incomplete are amenity=bicycle_parking and additional "micro-mapping" such as amenity=drinking_water (drinking fountains), shop=laundry and amenity=vending_machine nodes,
• highway=footway and footway=sidewalk (and highway=crossings, tactile_paving=yes, kerb=lowered, highway=elevators...) in areas beyond Downtown, especially to link business districts for pedestrian and disabled access,
• details of the back nine holes, disc golf courses and Grove theatre amenities at DeLaveaga Park,
• individual buildings in residential neighborhoods (houses, apartments...) added around the city,
• remaining amenity=post_boxes, amenity=fountains, amenity=charging_stations, amenity=clocks, amenity=telephones, amenity=benches, tourism=viewpoints, amenity=waste_baskets, barrier=fences, barrier=gates, natural=cliffs, amenity=drinking_water (drinking fountains), highway=crossings (crosswalks), leisure=pitches (sport fields and courts), leisure=playgrounds, power=poles, power=lines, power=substations, cycleway=shared_lanes (roads with sharrows and signs proclaiming "Bikes May Use Full Lane" and "Share The Road") and traffic_calming=bumps around the City.
City of Capitola
Zoning/landuse areas are good to very good, but minor improvements can still be made. A zoning map was available, but this link is broken as of 2019. A "Capitola Village" landuse=retail and some commercial zone wheelchair access have been added.
City of Scotts Valley
user:DanHomerick is a frequent contributor. An official zoning map is available, but it does not always agree with "on the ground" reality. OSM prefers reality over zoning. As noted above, while zoning is a good first step, reality is best.
City of Watsonville
Many contributions have been made, but OSM needs volunteers to improve Watsonville! An important next set of additions are bus stops to complement SCMTD Watsonville route expansion: OSM needs highway=bus_stop nodes added east of Seacliff and south of Aptos, along Airport and Freedom Boulevards.
