Different file formats are supported depending on the platform option.
GeoJSON files store coordinates in the JSON format. Both extensions are accepted: .geojson and .json. To validate and view your GeoJSON file, use the GeoJSON validator tool.
The coordinates of a valid GeoJSON Polygon should follow the right-hand rule:
- The coordinates are placed in a counterclockwise order.
- The first and last coordinates are identical.
If you need to apply the right-hand rule to your GeoJSON file, use the right-hand-rule rewinder tool.
If you want to preview or edit your GeoJSON file before creating an order, use the geojson.io tool.

.shp— feature geometry.shx— an index position.dbf— attribute information
Other optional files can be included in a shapefile as well, such as .cpg, .prj, .xml, .sbn, or .sbx.
Well-known text (WKT) is used to represent vector geometry objects. Allowed types of coordinates are Point and Polygon.
You can convert between the GeoJSON and WKT file formats using the GeoJSON to WKT converter tool.
