Here I show an example how to run a supervised raster classification in arcmap (ArcGIS 9.2) to classify an image in three simple habitat types. Tools used are "create signature" and "maximum likelihood". I have obvious the step of the training location data in which habitat types are linked to known locations. Please if anyone would like to show how to do this in the latest version of ArcGIS, ArcGIS 10, that'd be great. Also I would like to know the way in Arcmap to calculate the accuracy of the estimated new raster. Thanks a lot in advance if anyone posts this in youtube :)
