[GRASS-user] quickbird imagery: i.fusion.brovey, r.composite...

Hi List,

I’m trying to display a Quickbird imagery with nice real colors.

I tried with:

r.composite red=m1.red green=m1.green blue=m1.blue out=composite
i.fusion.brovey ms1=m1.green ms2=m1.nir ms3=m1.red pan=pan outputprefix=fusion -q

I tried also to set the RGB maps to grey und grey.eq but unfortunately until now the results are not very satisfying.

Any suggestion will be appreciated.

regards,
tommaso

Hi,

(Somewhat related but not entirely)

I am looking for cases/howto/examples of using quickbird images in
GRASS. Please refer some related:

orthorectification of quickbird in GRASS
change detection using quickbird in GRASS
image classification with quickbird (using texture, geometry and
spectra) in GRASS

Link I found so far:
http://geoinformatics.fsv.cvut.cz/wiki/index.php/Change_Detection_with_GRASS_GIS_-_Comparison_of_images_taken_by_different_sensors

cheers,
maning
