Defines a pixel grid on the Earth's surface using a map projection.
 - 
          
crsCodeis used for standard projections, whilecrsWktis used for non-standard projections. - 
          
affineTransformis included if the post-projection transformation is affine. - 
          
The coordinate reference system can be specified either by a standard code (
crsCode) or in WKT format (crsWkt). 
Defines a pixel grid on the surface of the Earth, via a map projection. If the projection has a standard code, then crsCode will be set (non-empty). If the projection is non-standard, then crsWkt will be set. If the post-projection transformation is affine, then affineTransform will be set.
