Last year I began importing Maryland Department of Natural Resources lands but my progress slowed as I reached the populated areas of Central Maryland. Today I have restarted the process a bit with a custom translation for Paul Norman’s ogr2osm tool.
Here are some beautiful new parks on the map:
- Patapsco Valley State Park, Howard County side (partially incomplete)
- Gambrill State Park, the state owned part
- Patuxent River State Park
Adding the parks is fairly manual but produces great looking map data. Let me know if you want to help out!
