Getting started
Publicly available resources useful for mapping in West Virginia:
- WVDOT Open Data Portal hosts GIS data provided by the West Virginia Department of Transportation.
- West Virginia Division of Highways GIS County Maps provides general highway maps in PDF format.
- MapWV.gov hosts several static and interactive maps of highways and POIs in West Virginia, many up-to-date.
- West Virginia Property Viewer provides a parcel/address database with reasonably recent E-911 data.
- West Virginia Trail Inventory shows reasonably accurate hiking and biking trail GPS traces.
- West Virginia GIS Technical Center hosts the state GIS Data Clearinghouse.
- DigitalCourthouse.com GIS Map Viewer showing parcels, owner info, and gas well locations. Also has PDF tax maps.

Current projects
- Gilmer County (Sterling) – somewhat thorough mapping.

Road tagging guidelines
Interstate Highways
.svg)
- Main article: Interstate Highway relations
Interstate highways should be tagged as highway=motorway and ref=I num (without a hyphen), and their route relations with network=US:I. Interstate ramps onto or from a motorway should be tagged as highway=motorway_link; destination=* tags should be added according to signage.
US Highways
- Main article: United States roads tagging § U.S. Highways
Most US highways in West Virginia will be tagged highway=primary, though this is not a hard and fast rule; some non-motorway divided highways (such as US 50 between Parkersburg and Clarksburg) are more appropriately tagged as highway=trunk. Controlled-access highways occasionally exist near (relatively) major cities, and should be tagged in the same fashion as an Interstate Highway. Tag all US highways as ref=US num, and their route relations with network=US:US.
State Routes
Most state highways in West Virginia can be either tagged highway=primary or highway=secondary, depending on the usage; occasional exceptions do exist, such as highway=trunk. Tag all state routes with ref=WV num, and their route relations with network=US:WV.
Do note that the WV Department of Transportation uses the term “trunk” in a different way than OSM does[1]. For example, WV 5 between Glenville and I-79 is considered a trunk road by the WVDOT, but would only be considered highway=primary by OSM standards as it is (relatively) low-volume.
County Routes
Most county highways—technically secondary state highways as they are managed by the WVDOT[2]—are most often tagged as highway=unclassified, highway=residential, or highway=tertiary. Tag all county routes with either ref=CR num for “whole number” routes, or ref=CR numerator/denominator for “fractional” (spur) routes (e.g. ref=CR 220/7 for the sign displayed on the right); tag their route relations with network=US:WV:County[note 1] and is_in:county=CountyName, where CountyName is, e.g., “Gilmer” or “Harrison”.
Do NOT tag county highways as highway=track; instead, use highway=residential or highway=unclassified, and some combination of surface=*, smoothness=* and/or tracktype=*.
Beware that TIGER can be notoriously inaccurate for county routes, especially small spur roads. Real-world examples[note 2] of such inexactitude include (but are assuredly not limited to): a ten-meter driveway being displayed as “State Route 47” on the latest TIGER overlay; ref=CR 7/3 being erroneously tagged name=County Route 73 in the original TIGER import; and three roads with identical names intersecting each other in the 2016 shapefiles.
Home Access Road Program (HARP)
HARP roads are almost always highway=residential. Tag all HARP roads with either ref=HARP num for “whole number” routes, or ref=HARP numerator/denominator for “fractional” routes, similar to the county route scheme; tag their route relations with network=US:WV:HARP and is_in:county=*.
Delta Roads
Delta roads are entirely defunct[3] despite the rare sightings of remaining signage. Do not tag delta roads in ref=*; instead, use old_ref=*.
Park and forest routes
- Main article: United States roads tagging § Tagging Forest Roads
Roads in nature reserves (i.e. parks) can generally be tagged as highway=unclassified or highway=path; use discretion as appropriate. National Forest Roads will use either ref=NF num for primary forest routes, or ref=FR num for secondary forest routes[4]. State Park and Forest roads (depicted right, though generally unsigned on-the-ground) are notated as ref=PFR num[5].
Officially labelled trails, meanwhile, are to be tagged as ref=TR num[4].
Other mapping information
Please follow OSM Good practices, especially by avoiding using wrong tags to “improve” rendering.
