Python scripts to convert USFS road and trail data to an OSM-compatible schema.
Status:
- Roads: mostly feature complete
- Trails: WIP; incomplete support for snow trails, motorized trails, and seasonal access restrictions
- Recsites: WIP; currently only trailheads are supported and other features are dropped
You can download the required datasets from the FS Data Clearinghouse. The specific datasets are "National Forest System Roads" (S_USA.RoadCore) and "National Forest System Trails" (S_USA.TrailNFS_Publish). You should download them in Geodatabase format (Shapefiles won't work with these scripts since the column names are truncated).
The "Recreation Opportunities" dataset can be downloaded as GeoJSON from the following URL: https://data-usfs.hub.arcgis.com/datasets/usfs::recreation-opportunities-feature-layer/explore
The justfile in this repo can be used to run the conversion using the just command runner. Or you can just paste the same series of commands into your shell.
The input files are assumed to be in ~/Downloads; edit the script to change this path if required.
The code requires a fairly recent version of Python (3.9+ I think?). It also requires the ogr2ogr command from GDAL, and jq for JSON processing.
The conversion applied by this tool is based on the interpretation of the USFS data described on the US Forest Service Data page on the OSM wiki.
