Raster.Matrix

Description

Name

class Tinman.Georef.Raster.Matrix

Derived from

Raster

A raster which uses an affine transformation from raster space to map space.

The following matrix will be used to transform raster space to map space:

          /   \     /            \  /   \
          | E |     | a  b  0  d |  | X |
          | N |  =  | e  f  0  h |  | Y |
          | 0 |     | 0  0  1  0 |  | 0 |
          | 1 |     | 0  0  0  1 |  | 1 |
          \   /     \            /  \   /

          X := Raster X-coordinate
          Y := Raster Y-coordinate
          E := Map easting coordinate
          N := Map northing coordinate

The given matrix must be invertible, so a*f - e*b must not be zero.
