Tagging suggestions for Ohio

Most of these examples are taken from the Cincinnati area, but feel free to add your own from elsewhere in the state:

Key	Value	Description	Examples
highway	motorway	Interstate highways, including loops and spurs; significant portions of US and state routes built to Interstate standards (high-speed, fully access-controlled).	I-71 I-275 Ohio Turnpike (I-76/80/90) Ronald Reagan Cross County Highway (SR 126)
	trunk	Selected U.S. and state routes not built to Interstate standards. High-speed, limited-access, divided highways with at least two lanes in each direction. May have occasional traffic lights and unlit street-level crossings, but mostly controlled-access with on- and off-ramps. Two-lane undivided (but still limited-access) sections of Trunk might make sense if they are extensions of divided Trunk highway or Motorway.	Appalachian Highway (SR 32) Columbia Parkway (US 50) Various Cincinnati viaducts
	primary	Other U.S. routes; major state routes, such as those that connect larger county seats not directly connected by US routes, or are important connectors between primary or higher roads. An example of which routes might be promoted to primary can be found here. Sections of primary roads generally should not "dead-end" at lower-class roads.	US 22 US 40 SR 4 SR 309
	secondary	Other state routes; good connecting roads, such as those that connect cities not directly connected by state routes, or are important connectors between secondary or higher roads. Sections of secondary roads generally should not "dead-end" at lower-class roads.	SR 48 Fra CR 3
	tertiary	County routes (signed or unsigned) and other major local roads, typically along section lines or connecting towns.	Loveland–Miamiville Road (CR 75)
	unclassified	Rural roads, serving mostly farmland or forest properties, of little to no value as through routes.
	residential	City/neighborhood streets not qualifying as tertiary or higher, or rural roads which have become lined with houses.
ref	I-##	Interstate highways.	I-71 I-670
	US ##	US highways.	US 40
	SR ## OH ## US:OH ##	State routes. The shorter forms are more likely to be rendered in Mapnik. While the US:OH form is specific, it doesn't look great on maps or in directions, and that specificity can also be accomplished using route relations.	SR 13
	CR ## C-##	County routes. This probably should only be used for roads where the county route number is signed as clearly as on a state route. The TIGER data often includes name_1=County Highway xx in counties that signpost county routes.
	TR ## T-##	Township routes. This probably should only be used for roads where the township route number is signed as clearly as on a state route.
maxspeed	105 65 mph	Most rural and suburban motorways and trunks.	I-270
	97 60 mph	Some urban motorways and trunks.
	89 55 mph	Most rural primary, secondary, tertiary roads. Some urban motorways and trunks.	SR 605
	80 50 mph	Some rural tertiary, unclassified roads. Some major urban and suburban roads.
	72 45 mph	Some rural tertiary, unclassified roads. Many major urban and suburban roads.
	64 40 mph	Some rural tertiary, unclassified roads. Many urban and suburban boulevards.
	56 35 mph	Some rural unclassified roads. Many urban and suburban feeder roads.
	48 30 mph	Some urban and suburban roads.
	40 25 mph	Many urban, suburban, and residential streets.
	32 20 mph	Some school service roads.
	24 15 mph	Many urban alleys.
	16 10 mph	Some private roads.
	8 5 mph	Some private (especially unpaved) roads. Generally, "aisles" in parking lots.

Note that speed limits in OSM are typically specified in kilometers per hour. However, you can now tag speed limits in miles per hour instead:

maxspeed=25 mph

Just remember to use a space and lowercase the "mph" abbreviation. See United States roads tagging for more information.

Relations

Route relations

Some highways are moving from the old way-based tagging scheme to the new route relations. Each relation should have network and ref keys, as well as a symbol key with the URL to the SVG image found on the highway's Wikipedia article. If the entire route has the same name, the name key may also be specified on the relation.

For divided highways in Ohio, roles are entered when adding relations to the constituent ways. (Potlatch provides a small textbox on the relation line for entering roles.) The de facto standard in Ohio is to add roles corresponding to the signposted direction of each carriageway (i.e., north).

Interstate highways

Mark all member relations as network=US:I. Please keep this list synchronized with Interstate Highways Relations.

Appalachian Development Highways

Mark all member relations as network=US:Corridor. Please keep this list synchronized with United States Numbered Highway Relations.

Corridor	Relation	Status and notes

C-1
D	114680 (XML, check, manage, JOSM, history, view, gpx )	Complete in Ohio. One relation for both directions, with role=east/west.

Forest routes

Mark National Forest Development Routes as network=US:NFD and Forest Roads as network=US:USDA:Wayne.

State routes

Main article: /Route relations/State routes

Mark all member relations as network=US:OH.

County routes

Mark all member relations as network=US:OH:ABC where ABC is the uppercase county abbreviation. (See map of abbreviations below.)

If used, county route relations can potentially become very numerous. Since such route relations should be, by definition, confined to a specific county, finding out if a particular route relation exists and its extent shouldn't be too difficult in map editors. For these reasons, a table of county route relations is not included here.

U.S. Bike Routes

Main article: /Route relations/Bicycle routes#U.S. Bike Routes

Mark all member relations as network=ncn; state=proposed; operator=AASHTO. Please keep this list synchronized with WikiProject U.S. Bicycle Route System.

State bike routes

Main article: /Route relations/Bicycle routes#State bike routes

Mark all member relations as network=rcn. The lettered routes below are designated by ODOT; tag them as operator=Ohio Department of Transportation. (Most other routes are maintained by county park districts. For such routes that cross county lines, tag the individual ways, not the relation.)

Boundary relations

• United States:  148838 (XML, check, manage, JOSM, history, view, gpx )
• Ohio:  162061 (XML, check, manage, JOSM, history, view, gpx )

Counties

County borders were originally supplied by the USGS. Those boundaries are not of great precision. Also, that import process created a lot of overlapping ways, and didn't use the admin_level=* key.

Much work has been done on the county boundaries. There is now a boundary relation for each county, and all county boundary ways have been split and merged as necessary so that only one chain of non-overlapping ways defines the boundary between any two adjacent counties. (Along Ohio's border, Ohio's county boundaries were merged with the TIGER-imported state boundary. Generally, the boundaries of counties in adjacent states have not been modified, and remain sourced from imprecise USGS data.)

There are still tasks to be done, however. Where county and city boundaries overlap, they should be merged; the merged boundaries should have admin_level=6, unless of course they're also part of the state boundary, which would be 4. The accuracy of the USGS-sourced boundaries can be improved, by following the endpoints of TIGER data or clues visible in the aerial imagery; these clues might include visible property lines, and especially natural waterways. Check USGS topo maps when in doubt.

A very important task pertaining to county boundaries is not about the boundaries themselves, though the work can be done at the same time other improvements to the boundaries are made. The TIGER dataset was imported county by county. As a result, roads that cross county lines aren't connected in the resulting OSM data. These should be joined by collapsing duplicate nodes. A little bit trickier is when a road follows a county line, it will be duplicated in OSM data. The road should be split where it joins or leaves the county line (if applicable) and then one copy of it deleted, then any duplicate nodes collapsed. Then, the county boundary should be made to follow the road by adding the road to the applicable counties' relations, adding appropriate boundary tags to the road's way, and connecting the rest of the county boundary to it. If this is done, there should not be a separate way parallel to the road representing the county line. This process might be called "TIGER welding".

Cities

The TIGER city limits have been imported for Ohio. There are a few pre-existing, hand-drawn boundaries that should be merged with the new data:

• Hamilton:  hand-drawn  TIGER (XML, check, manage, JOSM, history, view, gpx )
• Loveland:  hand-drawn  TIGER (XML, check, manage, JOSM, history, view, gpx )

The TIGER city limits import omitted the customary name:left=* and name:right=* tags on the ways that some renderers might potentially use to display both adjacent cities. Please consider adding them where appropriate. (To determine "left" and "right", imagine that the way is a oneway road and you are driving down that road.)

CDPs

In the city import process, census-designated places were included, which are not real cities; but just like actual cities, they were added with boundary=administrative and admin_level=8. They're just areas drawn arbitrarily for the Census for statistical purposes.

There seems to be agreement on talk-us that these shouldn't be tagged with boundary=administrative at all.

Clues that indicate a boundary might be a CDP is that it primarily follows roadway centerlines, and doesn't reflect well the actual boundaries of a community; that is, it might strangely omit houses on one side of the road, or it might include large chunks of farmland. One way to identify a CDP with certainty in Ohio is in its relation's tagging. The tiger:NAMELSAD tag will have the CDP's name with "CDP" added to the end. Wikipedia will also have an article on any CDP or municipality in Ohio, identifying whether or not it is a CDP. Finally, the Wikipedia article for each county in Ohio will have a section listing CDPs it contains, if any.

Since these CDPs do not relate to anything administrative, they should probably be stripped of their border=administrative and admin_level=8 tags. This should be done on the relation, and on the ways that make up the boundary (unless of course the ways are also parts of other administrative boundaries). The relation should retain its place=locality tag.

County Abbreviations

ODOT has a system of 3-letter abbreviations for each county in Ohio. For most, the abbreviation is the same as the first three letters of the county name, but there are exceptions. These may be generally useful to us in a number of ways.

To do

• The map is still missing most of Ohio's major bicycle routes, such as the Ohio-to-Erie Trail, of which only the Little Miami Scenic Trail has been mapped. Some counties have begun numbering these routes, so inclusion in OpenStreetMap could be very helpful.
• Some counties in Southwestern Ohio are now using Relation:boundary along shared ways for their borders.
