Class PixelScale

  • public final class PixelScale
    extends Object
    This class is a placeholder for defining exact affine transformations between raster and model space.

    Quoting the geotiff spec:

              Tag = 33550
              Type = DOUBLE (IEEE Double precision)
              N = 3
              Owner: SoftDesk
    This tag may be used to specify the size of raster pixel spacing in the model space units, when the raster space can be embedded in the model space coordinate system without rotation, and consists of the following 3 values:
           ModelPixelScaleTag = (ScaleX, ScaleY, ScaleZ)
    where ScaleX and ScaleY give the horizontal and vertical spacing of raster pixels. The ScaleZ is primarily used to map the pixel value of a digital elevation model into the correct Z-scale, and so for most other purposes this value should be zero (since most model spaces are 2-D, with Z=0).

    A single tiepoint in the ModelTiepointTag, together with this tag, completely determine the relationship between raster and model space
