Raster

Description

Provides a mapping from raster coordinates (i.e. pixel X and Y) to map coordinates (i.e. easting and northing).

Consider the following point raster (where each O represents a single raster element):

             0   1   2   3   4   X-axis

          0  O---O---O---O---O
             |   |   |   |   |
          1  O---O---O---O---O   Top-left coords     := (0|0)
             |   |   |   |   |
          2  O---O---O---O---O   Bottom-right coords := (4|3)
             |   |   |   |   |
          3  O---O---O---O---O

          Y-axis

The origin of a raster (i.e. the raster coordinates (0|0)) are always located at the top left corner. The positive X-axis points to the right and the positive Y-axis points downwards.
