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 :)

  • Thank you so much! Would it be possible for you to explain how did you create that habitat layer? Thanks again.

  • isn`t it possible to crate signatures from Polygons? thsi should lead to an improved signature set.

    anyway: i`ll do this in ArcGIS 10 for you this night... ;-)
