class Tinman.Georef.Raster.Matrix

Short Name:
  • class Raster.Matrix
Derived From:
Fields:
  • required a
  • required b
  • required d
  • required e
  • required f
  • required h

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.
