<br><br>Have Modis images MOD13Q1 reprojected into Tiff format imported
into grass to analize NDVI for different months and seasons. As I just
need to analize NDVI for a <b>specific crop area </b>of the image imported, I want to extract or select that region from the raster map.
<br><br>After reading several post explaining that R.region/G.region
should be use to set the geographic boundaries, I decided to follow the
instruction and have use <b>r.region</b> setting nort, south, east and
west values of the smaller area BUT only get the same image narrower in
width and longer in high.
<br><br>Now, when I follow the use of this command again I get the message "unable to parse command r.region"
<br><br>I'm new in Grass! and feel confuse. What I am missing? Please help! Many Thanks in adavance.
