,Function
Interpolation: Transformation of continuous values by a function defined on a number of nodes. This is used to adjust
the value distribution of an attribute to the desired distribution of a continuous symbolization control variable
(like size, width, color, etc).
In case the Categorize (or Interpolate) function is used inside a RasterSymbolizer as a ColorMap, the LookupValue is set to the fixed value “Rasterdata”.
