I'm using grass 7.0.1 and my goal is to create a NDVI map with a sharper resolution from a landsat 8 image. I did the transformation from 16bit to 8bit, and afterwards i used the i.pansharpen module. In the final step i tried the i.vi module. The result was a ndvi map with the original resolution of 30*30 pixels. I also tried to export each sharpened band separately, but i'm facing the same problem, that of the lower resolution... Any ideas??? Thanks in advance!!
