GEO.JSON function creates a WarpScript object (GEOSHAPE) representing a geographical area. The description of the geographical area uses the GeoJSON format.
The coordinates are assumed to be in WGS 84.
A GEOSHAPE is a set of cells at various resolutions which cover (or are contained within) the specified area. The resolutions of the cells are even numbers from 2 (coarsest) to 30 (finest) with the following associated precisions at the equator:
The exact precision is 40,000 km divided by 2**resolution.
The number of cells that a GEOSHAPE may contain is limited by the platform configuration, this limit can be modified up to the hard limit using
