RasterValueAttributeSet Class
Associates a thematic raster value with an AttributeSet.
NuGet/Assembly: Carmenta.Engine.5.16.2.nupkg (in the CECore assembly)
Syntax
public class RasterValueAttributeSet : EngineObjectRemarks
In a thematic raster raster, the cell values are integers that represent discrete categories like land use: one could for example use 0 for WATER, 1 for FOREST, 2 for CITY, etc. An instance of this class represents an association of such a value with a set of attributes. So, the thematic value 1 could be associated with an attribute LandUse with the string value "Forest" and an attribute EstimatedHeight with the float value 25.0, etc.
Some raster datasets, ImageDataSet and GdalDataSet, can read metadata that define a collection of RasterValueAttributeSet instances, one instance for each possible raster value. The collection, known as a raster attribute table, will be accessible as a component of the DataSetInfo for the dataset. The raster attribute table can also be referred implicitly from an ImageQuery or a GdalQuery for the dataset.
