GeoJSON (*.json;*.txt)

GeoJSON is a format for encoding a variety of geographic data structures.

GeoJSON supports the following geometry types: Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection. Features in GeoJSON contain a geometry object and additional properties, and a feature collection represents a list of features.

This is a Memory Dataset.

The following example GeoJSON is for a simple Polygon item:
