Now that I finally have a DEM, satellite imagery and ground truth
data for my study area, I have (enjoyed) the opportunity to
try out some of the really nice features in GRASS that were
previously impossible. I do have a couple of questions related to
image classification:
1) I can't seem to slide colors while running d.colors. I have set
d.colormode mode=float beforehand, but no pixels change colors
once I am actually in d.colors. I am running GRASS4.0 on a
SPARCstation1 under OPENWINDOWS. I should mention that I am
able to slide colors if I select SUNVIEW as my GUI. Has anyone
else reported this problem?
2) What happended to mapmask? I was reading the 4.0 manual entry
on r.mask, and it refers to r.mapmask. Yet, r.mapmask is not
listed as a command in the manual. Nor is the command found if
I enter it at the GRASS 4.0 prompt. I need to make a number of
circular-shaped binary masks for my analysis. Is there another way
to accomplish this?
Thanks in advance for your help!
