Geojson polygons for parks in St. Louis (MO) County.
The data is incomplete. Most of the park names are missing. Please submit pull requests to improve the data.
An easy way to do that is to open the file: http://geojson.io/#id=github:gavreh/st-louis-mo-county-parks/blob/master/st-louis-county-parks-names.geojson&map=11/38.6470/-90.4201
... make your edits, save to GeoJson, and submit a PR.
Thanks!
