How to using DEM as adding information and CART Analysis on Ecognition ?

Hello Friends,
Currently, i have some researches about object classification. I am using ecogniton before, but i am hardly knowing how to use DEM as a thematic layer on that. How to add altitude information from DEM into our ruleset? Is there anything feature represent altiltude (DEM) ?
I also want to use CART analysis as decision tree for choosing some features to split all my class. But, i dont know how to use it. I ask the author from paper i read, he told in ecognition 8, CART already b
ASTER - free satellite images for download
By Arhanghelul,
Hello !
I would like to find some ASTER satellite images over Europe (east Europe) and I ask if someone can help, give me some informations about ordering the images.
I know that ASTER Level 1B scene products can be obtained for-free only for US territory, but not for international scenes.
Is there a way to obtain that tipe of images for educational-research utility for free, no money ?
P.S. I am looking for the ASTER satellite images (VNIR, SWIR and TIR), not the DEM.
Thx.

SSN and STARS: Tools for Spatial Statistical Modeling on Stream Networks
By jonah,
Spatial Autocorrelation in Streams and Rivers:
Tobler’s first law of geography states that, ‘‘Everything is related to everything else, but near things are more related than distant things.’’ In the field of spatial statistics, this phenomenon is referred to as spatial autocorrelation. Spatial statistical models tend to make more accurate predictions when data are spatially correlated. However, in rivers and streams there’s an extra complication because both Euclidean and in-stream distances c
