You can’t make a #map without #data. A wealth of free and publicly-accessible geospatial data exists on thousands of independent websites scattered around the world, but tracking down these websites can be a challenge. Geolode is a collaborative #catalog of open geodata websites around the world, searchable and browseable by location, topic, and other tags, so that searchers can quickly focus on the most relevant websites for their geodata needs.
