Dear Moritz and all
r.stats or r.report
Thank you for profitable advice.
When this command was used, the table is output as follows:.
|---------------------------------------------------|
| Category Information | square |
| #|description |kilometers|
|---------------------------------------------------|
| 1| . . . . . . . . . . . . . . . . . .| 37.30|
| 2| . . . . . . . . . . . . . . . . . .| 5.89|
| 3| . . . . . . . . . . . . . . . . . .| 5.89|
| 4| . . . . . . . . . . . . . . . . . .| 7.85|
This means that your elevation map is already a reclassified map with
elevation classes, but that you did not include the information about
the classes in the reclassed map. I.e., using r.reclass, you can do
something like this:
0 thru 10 = 1
but if you want to keep the information about the class amplitude, then
you have to do this (adding a label to each class):
0 thru 10 = 1 0 - 10m
You can also add labels to the existing classes, using r.category. Just
create a text file:
1: 0 - 10 m
2:11 - 20 m
3:21 - 30 m
...
and run r.category map=YourMap rules=TextFile.
Then r.report will include these labels.
