What is a geoJSON file?

A GeoJSON file format is an open standard format that contains both geospatial and attribute data. The GeoJSON format is extended from the standard JSON (JavaScript Object Notation) format and usually ends with a .geojson suffix. As mentioned, GeoJSON files contain both geospatial and attribute data — they are therefore able to function without any additional files. This format is popular in development, and is also often used by GIS software such as QGIS, ArcGIS, Tableau Software, and our own Spotzi Geomarketing Platform


A complete geoJSON dataset contains the following specifications when exporting from Spotzi:

The_geom and the_geom_webmercator contain all the data for drawing points, lines, or polygons. Another type of geoJSON may look like the following example — this example doesn't contain a geom and geom_webmercator, but instead contains the coordinates or strings of coordinates for points or lines and polygons respectively.
