GeoJson

GeoJson is a standardized format of how to display geometry in a geographical context, using latitude/longitude pairs to display one (or multiple) Point, Line or Polygon.

This implementation is roughly based on RFC7946.

GeoJson objects consist of two objects:

type: The type of the object. All listed in the table below.
coordinates: The coordinate point(s)* of which the object is composed.

The points are an array of exactly two values in the format [longitude, latitude]. Here the implementation breaks with the standardized format, as multiple point formats can be used for convenience (see Point section).

MultiPolygon

Point

Points represent a single point on the map. In the following all valid coordinate types are shown

Line

The line can be used to show a path or connection between multiple points.

Polygon

Polygons are used to represent shapes. They are an array of two pointarrays. The first represent the shape, the optional second one a hole that can be cut into the shape.

MultiPolygon

Multipolygons are an array of polygons.

Applying GeoJson Objects to the Map

The GeoJson data is used to create a GeoGraphics object.
