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.
