These new properties are unsigned because the existing ColumnStartFrom and

RowStartFrom properties already provide directional information.

These new properties make the DeltaLat, DeltaLon, DeltaX, and DeltaY properties

redundant. These older properties still exist but are hidden.

The four new classes replace the two existing classes

spatialref.GeoRasterReference and spatialref.MapRasterReference.

georasterref, maprasterref, and worldfileread functions

return new types

The georasterref and maprasterref functions return new types of objects, depending

on the value of the RasterInterpretation parameter. By default, if you do not specify

this parameter, the functions return an object with the raster interpretation cells.

The worldfileread function returns new types of objects, depending on the value of the

coordinateSystemType parameter.

The following table lists these classes.
