Classifying and converting raster data to vector data

This example model uses the FMO and the RAS2POLY modules to classify raster data and to convert the classified raster data to vector data, respectively.

The FMO module performs MODE filtering to remove complex mixes of pixels from the raster to create a classified raster that is easier to interpret than the original raster. The RAS2POLY module then converts the classified raster to a vector file in ArcView SHP format for export to a vector geographic information system (GIS). The RAS2POLY module creates vector polygons that group adjoining pixels that were assigned to a feature or a class during classification by the FMO module. The vector output is then displayed on top of the original raster layer in a viewer.
