ScaledConverter class abstract

A coordinate converter between geospatial positions and scaled coordinates.

Geospatial positions may represent geographic or projected coordinates defined by a spatial coordinate reference system.

Scaled coordinates are projected coordinates scaled to a defined range most often defined by a tiling scheme.
