[GRASSLIST:1674] ASTER

[Ivan Marchesini]

Hy to all

can someone say me where I can find some information about how to use RELATIVE 
ASTER DEM???
I have downloaded some of these granules, but using the area of 
superimposition between them I discovered that the z elevation is quite 
different between each other....

I tried to see documentation but it is not really clear....

have I to use GCPs???
or similar??
thank you very much.....

Ivan
