GEO.GML function creates a WarpScript object (GEOSHAPE) representing a geographical area. The description of the geographical area uses the
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
Since 2.4.0, you can easily visualize geoshapes in WarpScript editors. See example.
