These in-development tools will allow park agencies and other trail stewards to upload and transform their existing shapefile data describing trail systems--including trail segments, trailheads, and the areas they traverse--into OpenTrails-compliant GeoJSON and CSV files.
The converter tool currently transforms shapefiles containing trail segment data (lines), producing:
trail_segments.geojsonnamed_trails.csvstewards.csv
Future functionality will provide a similar transformation for shapefiles describing trailheads (points) and areas (polygons).
OpenTrails is a Python Flask application that depends on Amazon S3 for storage of uploads.
