Abstract
A system and method that facilitates planar processing of round earth data by employing a tiled projection is provided. The tiled projection is a two-step projection from the surface of the earth to a common plane that preserves polygons and polygonal paths. During the first step, the system performs a gnomonic projection to the facets of a circumscribed platonic solid, which maps spherical polygons to spatial polygons on the facets of the solid. During the second step, the system performs a polygon-preserving projection from the facets of the platonic solid to tiles in common plane. Thus, projections from multiple facets of the platonic solid on the common plane are processed by employing a planar algorithm.
