[GRASS-user] No statistics output

Hi list,

I read in some geotiff raster files and wanted some basic info about cover per class etc.

When running r.cats I get the following output:

1
5 Hwe-
6 Hg
8 Gt–
9 Gpap
10 Gpar
11 Gpnd
12 Gpj-
13 Fcpc
14 Fcps
15 Fdb-
16 Fdqz
17 Sb-
21 Wo
23 Ac

When running r.stats I get an empty sheet, other statistics which include categories also turn up empty. Any idea what’s going on? It looks like the stats functions don’t recognize the categories. Also when using the query tool in the map display the values of the underlying pixel don’t show (only * → example query output: r.what -f input=BWK-reclassed-HABISTAT east_north=154253.966939,232124.628713 = 154253.966939|232124.628713||*).

Kind regards,
Koen

Most likely your current GRASS region does not cover the map.

g.region rast=BWK-reclassed-HABISTAT

should help before running the other commands.

Restarting GRASS seemed to have resolved the issue. It stays weird, anyway if it disturbs my batch process I’ll report back.

Cheers,
