[GRASS-user] High-resolution agricultural land cover from satellite imagery

[山田 康晴]

I wonder why you want to use the Landsat TM data for the analysis of
the high resolusion agricultural land cover.


The Landsat TM, not ETM, has very long histry and is not the High-resolution
 data as for both spatial and frequential points of view.
There are so many research papers for the analysis on agricultural
land cover.

The "esa" or Italy scientists must have much information for your interest.
Are you a scientist in Italy?
