Hi, I've been trying for 2 or 3 days now to get some nice looking images out of MODIS TERRA/AQUA 500m land products (ie 7 bands). I've seen the screen shots and see the quality of the images that can be obtained--but at best I some very faded/obscured images. I've loaded the data into GRASS using HEGTool to convert the HDF file to separate bands. I've then loaded that and tired combining Bands 143 (RGB) using r.composite. I've tried using r.colors' standard grey scale and grey.eq before making the composite image. My values for the images ranges from -28672 to approx. 9000 .
I've tried rescaling the data to get it between 0 and 255, and the resulting image quality is equally bad. Any suggestions on what to try next? I've checked the data out in other programs that are in other research groups and the data makes nice RGB images--so nothing wrong with the source data.
