NDVIFunction

Base Type: RasterFunction

A class for a raster NDVI function.

Remarks

Calculates the Normalized Vegetation Differential Index values given a 2 band raster consisting of the Red and NIR bands. The ColormapFunction can then be used to visualize the values.

Examples

C#

RenderingRule renderRule = new RenderingRule();

NDVIFunction function = new NDVIFunction();

NDVIFunctionArguments argument = new NDVIFunctionArguments();

argument.Names = new string[] { "VisibleBandID", "InfraredBandID" };

argument.Values = new object[] { visualBand, infBand }; //0-based integer

renderRule.Arguments = argument;

renderRule.Function = function;

renderRule.VariableName = "Raster";

geoImgDesc.RenderingRule = renderRule;
