37 geoJSON/topoJSON

The geoJSON and topoJSON formats are derived from JSON for representing collections of simple geographical features along with their non-spatial attributes. Among the possible features that can be stored in the GeoJSON/topoJSON standard are "points," including addresses and locations; "line strings," including streets, highways and boundaries; "polygons," including countries, provinces or tracts of land; and multi-part collections of these types. The differential of topoJSON compared to GeoJSON is that it stores geospatial topology and typically provides smaller file sizes.
