<H4>SPANS Quadtree (MAP)</H4>
SPANS quadtree format is the format for the Tydac SPANS products.
The Tydac SPANS quadtree format is used by SPANS to store raster data
as a matrix of variable sized square cells. This storage format results
in finer cell resolution in the vicinity of boundaries and larger cell
resolution where a finer resolution is not necessary. The total storage
size of the data is reduced with this storage format for classified data.<p>
The GeoGateway library supports SPANS quadtree files for read access, and
they will have the extension .MAP.<p>
The GeoGateway library supports SPANS quadtree files which are 8U and 16U.<p>
Projection and georeferencing is not supported with this format.<p>
A SPANS quadtree only contains one band.
