Suggested Discussion Topics
- Mapping State Parks.
- Mapping Rivers
- Should river banks be mapped using the technique shown here waterway=riverbank. If so, should the riverbank be a part of the river's relation?
- Should the rivers Name only exist on the Relation? Or, on the riverbank and every segment of river way?
- See the Grand River and the Huron River as examples of the different riverbank mapping schemes.
- How to reconcile the three points that should be in the same location (two monuments points and the corner of the townships) in the Meridian-Baseline State Park.
The consensus was to merge the mysterious and inaccurate survey marker with the historical marker and average the locations from GPS traces and Mapillary imagery.

Common Tagging Schemes
This is intended to function as a cheat sheet for mapping common features found in Michigan. Follow the links for detailed instructions. Please update any that no longer match their state of the art.
- Amphitheater amenity=theatre + theatre:type=amphi
- Disc Golf Course leisure=disc_golf_course + sport=disc_golf
- Little Free Library amenity=public_bookcase + brand=Little Free Library + ref=#
- Food - Food establishmebent tagging is not always clear cut.
- Bar - amenity=cafe Similar to a Pub, but louder. Think sports bar. If they sell food, add cuisine=*.
- Cafe amenity=cafe Consider using Fast Food or Restaurant, if the meals are substantial.
- Fast Food amenity=fast_food Any place meals are ordered and served without waitstaff.
- Restaurant amenity=restaurant Any place meals are ordered and served by waitstaff.
- Pub amenity=pub Similar to a Bar, yet quieter. Think Kelly's. If they sell food, add cuisine=*.
- Pavilion amenity=shelter + shelter_type=picnic_shelter
- Playground An area tagged as leisure=playground
- Sledding hill leisure=playground + playground=sledding
- Houses = Often, Michigan houses will be building=detached. For other options see the list at building=house.
- Apartment Complexes = a point within or way surrounding the complex with landuse=residential + residential=apartments + name=* Could also add tags like addr:housenumber=* + addr:street=*
- Parks = For city or village parks tag a point or area as leisure=park. For other public lands see below.
- Neighborhood = a point within or surrounding way place=neighborhood + name=*
- Shopping Center = a point or way surrounding the area with landuse=retail + name=* Could also add tags like addr:housenumber=* + addr:street=*
Current status tracked at Michigan/Parks.
Use tags found at United States/Public lands. In general, the boundary of a State Park will be tagged as:
- protection_title=State Park
- name=* Official name on the sign.
- owner=State of Michigan, Department of Natural Resources
Park amenities should be tagged using the US National Park Service Tagging Guidelines.
Sidewalks / Footways
Unless explicitly prohibited bicycles are allowed on footways in Michigan and should be tagged as follows:
Where bicycles are prohibited remove the "bicycle" tag (bicycle=no is implied).
Paths / Trails
See Michigan/Trails for current state of mapping Michigan trails.
Multi-use paths (like the Lansing Rivertrail):
- Some sections could also use flood_prone=yes.
Paths/Sidewalks only for bicycles (rare in Michigan):
Woodland trail, bicycles allowed:
Long trails should be mapped as a route relation using the following tags. Then add the trail and other related object this relation.
- ref=* Initials of the trail.
- Please try to follow the Bike-Ottawa Tagging Guide when tagging bicycle features.
- Be careful not to tag a narrow shoulder with a fog line as a bicycle lane (shoulders as wide as a car should be tagged with shoulder=*). A true bicycle lane will be wide enough, based on speed of the road, and be marked as such. See the regulations.
- We are looking good on:
- CycleStreets is a UK-wide cycle journey planner system, which lets you plan routes from A to B by bike. It is designed by cyclists, for cyclists, and caters for the needs of both confident and less confident cyclists.
- PlacesForBikes is a program that helps quickly build and connect great places to ride. Then we measure their benefits: More people riding more safely makes communities better places to live, work and play.
- Two popular bicycle map renderers are the mobile app OsmAnd and the interactive map website CyclOSM (now available on OpenStreetMap.org.
Water; Lakes, Rivers, Streams, Creeks, Drains
See Michigan/Trails state of water trail mapping.
Rivers should be tagged following the instructions at waterway=*. Wide rivers should also have their riverbanks mapped as shown at water=river. Long rivers should have a route. Though it should be possible to move most of the tags to the Route, it is best to also have the name on the larger sections of the waterway.
Water trails should be tagged as a route relation using the following. Where appropriate, add the waterway, access points and objects directly related to the relation.
Other water related tags schemes:
- Boat launch, place a leisure=slipway point at the waters edge, at the end of a service road.
- Canoe, kayak and other paddlecraft access sites usually have a way leading to a point on the waters edge, tagged as whitewater=put_in;egress + whitewater:put_in;egress=* pier / steps / ground + description=*. To designate one as handicap accessible, add the tag wheelchair=yes.
- Portages are ways leading between put_in/egress points, tagged as whitewater=portage_way.
- Low head dams, like in Lansing, are ways with the high side on the left tagged as waterway=weir.
- General hazard = waterway=hazard.
- Fish ladder = waterway=fish_pass.
- Boat/ Canoe/ Kayak rental = amenity=boat_rental + canoe_rental=* + kayak_rental=*.
- Docks = man_made=pier + floating=* + highway=footway + surface=* + area=yes
- Boat store = shop=boat + boat:type=*
- For mapping other canoe / kayak / SUP / paddle craft interests, use whitewater=* tags (until better named tags have wider support).
The Android app OsmAnd has a Boat profile for viewing, planning routes on and navigating waterways. To show whitewater/paddlecraft objects, open Plugins > enable Nautical map view. Switch to the Boat profile then, Configure map > Routes > check the box for Whitewater sports.
See Michigan/Railroads for current state of mapping Michigan railroads.
The current status of our highway mapping is found on the page Michigan/Highways.
As OpenStreetMap is used more and more for routing, by even fully autonomous vehicles, it is important to accurately map roadways. Here are helpful links for mapping key areas:
- Mapbox: Mapping for navigation
- maxspeed=* + maxspeed:type=sign
- When possible, to accurately map the center of the roadway, capture and use GPS traces as aerial imagery often has an offset.
Use the same relation tagging scheme for Michigan State Highways as for Interstate Highways Relations, except use network=US:MI, US:MI:BUSINESS, US:MI:DOWNTOWN, US:MI:FUTURE. Don't give the relation a name=* unless the entire state highway has exactly that name all the way.
Until all renderers fully support highway relations, it is probably also a good idea to tag ref=M xx on the ways making up the relation.
See United States Highway Classification for the most up to date information on this topic.
The primary language and terms of OSM is UK English, which can be confusing. Use the table below to properly categorize streets in the area. Some effort has been made to cross-reference the National Functional Classification (NFC) numbers found using the State of Michigan NFC Map to the equivalent OpenStreetMap highway type. Please edit any errors, or start a discussion accordingly.
|State's NFC name (#)||OSM Type||Description|
|Interstate (1), Other freeways (2)||highway=motorway||Limited access freeway with interchanges. Access via on/off ramps with merge lanes, divided road of at least 2 lanes each direction. Called "Freeway." Speed limits generally 55 MPH or higher. Examples; 127, I96, I69, 496|
|Other Principal Arterials (3)||highway=trunk||
Rural: Nearly a freeway. Example, 127 North of St Johns.
Urban: May have cross traffic, but traffic flow on the trunk always has the right of way (except at red traffic lights). Speed limits usually 45 MPH or higher. Example, Saginaw Highway east of East Lansing.
Note, this is unrelated to our similarly named "State Trunkline" which the State of Michigan defines as, "all roads under MDOT jurisdiction, including all Interstate routes, US routes, M routes, Interstate business loops and spurs, US business routes, M business routes, connector routes, and unsigned state trunkline in Michigan."
|Minor Arterials (4)||highway=primary||
Rural: When tempted to tag a rural road as "trunk", it is probably an OpenStreetMap "primary" highway. Examples; M 52, M 99, M 100, M 115.
Urban: Three lanes or more each traffic direction. 35 MPH or faster. Handles large volumes of traffic. (Any or all of these). Examples Saginaw and Oakland through Lansing.
|Major Collectors (5)||highway=secondary||
Rural: The next class of roadway off a primary.
Urban: Two lanes of traffic each direction. 35 MPH or faster. Medium-high traffic volumes. Examples; Cedar Street and MLK in Lansing.
|Minor Collectors (6)||highway=tertiary||
Rural: If not sure, consider "unclassified", "residential", or "service".
Urban: Lower traffic volumes on wide streets, or higher traffic volumes on narrow ones. Examples; Mt. Hope, Jolly, Okemos, Willow, Creyts, Meridian
|Local (7)||highway=unclassified||The least most important through roads in a country's system – i.e. minor roads of a lower classification than tertiary, but which serve a purpose other than access to properties. For instance, minor country roads, often linking villages and hamlets. (The word 'unclassified' is a historical artifact of the UK road system and does not mean that the classification is unknown; you can use highway=road for that). Examples; Washington, College, Farm Lane, Freiermuth, Dobie.|
|Local (7)||highway=residential||Roads which serve as an access to housing, without function of connecting settlements. Often lined with housing. Single traffic lane each direction, may also be oneway=yes. Usually 25 MPH or slower. May have traffic bumps and other "traffic calming" measures. Examplesl apartment complexes, neighborhood roads|
||For access roads to, or within an industrial park, camp site, business park, car park etc. Can be used in conjunction with service=* to indicate the type of usage and with access=* to indicate who can use it and in what circumstances.|
|Highway link||Short connecting ways, like highway or round-a-bout entrances and exits and "Michigan turns".|
Ways Under Construction
To flag a way as under construction use Conditional restrictions. Given an end date the restriction should be inert if forgotten, but it would be best to set a reminder to remove this tag when no longer needed.
- All access:conditional=no @ (2021 Aug 1-2021 Nov 30)
- Cars, trucks, motorcycles, etc. access:motorcar:conditional=no @ (2021 Aug 1-2021 Nov 30)
- Bicycles access:bicycle:conditional=no @ (2021 Aug 1-2021 Nov 30)
- Pedestrians access:foot:conditional=no @ (2021 Aug 1-2021 Nov 30)
