<DIV><BR></DIV>I am sure other members of this list can answer your question
better than I, but usually create an indexed color tiff before importing it
onto GRASS. The GIMP does a very nice job of this. If you a bringing in more
than one TIFF, be sure you use the same palette for all the
images.<BR><BR>Once you get all your images into GRASS, use the r.patch
command to mosaic them together.<BR><BR>To reproject them, use r.proj. Your
state plane coordinate system should be on the same datum as your lat/lon when
you use r.proj because while r.proj does a great job of reprojecting, it does
not handle datum transformations.<BR><BR>Rich<BR><BR>At 04:15 PM 11/14/2002

All,</FONT><BR> <BR><FONT face=arial size=2>I'm a new user to GRASS and
I installed it yesterday, and did the tutorial with the spearhead sample
data online. Anyhow, now that I have some sort of idea of what I'm doing,
I'm running into some trouble. I have a bunch of data, and I would like to
make a mosaic of it, then reproject it into LAT/LON. The current projection
is State Plane. Here is what I've done so far.</FONT><BR> <BR><FONT
face=arial size=2>I have imported the .tif files (with the .tfw) into GRASS,
and it separates it into the RGB bands. So what I did was, I used the d.rgb
command to display the image, but the colors come out all weird, how do I
make it display the real colors. I have also tried using r.in.gdal but when
I display that, it comes out black and white. I have also tried r.composite
and it also displays weird colors (like a flash back to the 80's with neon
colors and all)</FONT></BLOCKQUOTE><X-SIGSEP>
