[GRASSLIST:1793] Urban Classification

[Martin Wass]

Grass Users !

Do any body know how to make an urban classification for an
Landast TM picture.

I got an tips from Erdas mail list to read an intressting document at
http;//www.epgaz.com/remotehome.htm in this document they use ENVI
to calculate out an new Entopy layer wiht an 17 * 17 GLCM matrix
for an Landsat TM picture and they do resive beter results.
I don't have ENVI.

I am hopping fore more help how to make an Urban classification.
I have tryed i.smap and i.maxlik

r.nntool and r.affinity do not work on my SUSE box.
