The GEO.COVER.RL function creates a WarpScript™ GEOSHAPE representing a geographical area at a specified resolution.

The area is composed of geo cells which cover the path of an input Geo Time Series™ or GTS Encoder. The path is considered to follow rhumb lines, hence the function suffix .RL.

The resolution of the cells is an even number from 2 (coarsest) to 30 (finest) with the following associated precisions at the equator:

ResolutionPrecision
210,000 km
42,500 km
6625 km
8156 km
1039 km
1210 km
142.5 km

18150 m
2040 m
2210 m
242.5 m
2660 cm
2815 cm
304 cm

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 MAXGEOCELLS.
