I am a first time GRASS user working on a project through the Department of Transportation. We’re trying to visualize LiDAR data we have collected from a particular segment of roadway so that we can better analyze and present our finding to the DoT, and I have been encountering some issues following the tutorial found here.
When using the Serpent Mound data available from this site as well as my own data, I start encountering problems while attempting to use the g.region command. It says that n= max x etc is an invalid input. I think this is because the g.region is stuck on LAT/LON units for this, however trying to use the LAT/LON from my own data has not worked either, and I do not know how to access the LAT/LON data for the Serpent Mound set.
How do I make the program accept my g.region inputs?
I tried to move on with the other commands despite g.region not working, and encountered more issues. When I inputted the r.in.xyz (…) command it said “Reading data…” but when I tried r.colors it said “ERROR: Bad y-coordinate line 1 column 2”
My ultimate goal for right now is to replicate these results with my own data. After that we would like to experiment further with the advanced capabilities of the program, but a colored visualization of the data would be great for right now.
Thanks in advance!
