Detailed Description

Responsable for the geografical and projectional transformations related to reading and writing in raster maps.

Definition at line 49 of file Map.hh.

Constructor & Destructor Documentation

Map::Map

(

Raster *

rst

)

Create a new map based on a predefined raster. The Map takes ownership of the Raster object pointed to by rst. It will be deleted when this is deleted.

Parameters

rst	Raster object

Definition of Map class.
