A simple solution would be
dict_region = grass.region()
instead of
info_region = grass.read_command('g.region', flags = 'p')
dict_region = grass.parse_key_val(info_region, ':')
but that does not solve the problem of resolution being in degrees. For ll,
you would need to get the resolution for each raster row separately, or
estimate with
r.mapcalc "ll_resolution = sqrt(area())"
which probably doesn't make sense for higher latitudes.

Hi Lara, as far as I remember, it worked only in projected coordinate system. Hope this helps, Kind regards, On Fri, May 24, 2019 at 3:41 PM Lara DC wrote: > Dear users > I am new with Grass.

[GRASS-user] r.hazard.flood extension
Dear users I am new with Grass. I am trying to use the r.hazard.flood extension but I get the following error: Traceback (most recent call last): File "/home/lara/.grass7/addons/scripts/r.hazard.flood", line 145, in sys.exit(main()) File "/home/lara/.grass7/addons/scripts/r.hazard.flood", line 78, in main resolution = (float(dict_region['nsres']) + float(dict_region['ewres']))/2 ValueError: invalid literal for float(): 0:00:00.17656 Any idea of what can be wrong? my dem file (named fmosaic) is type raster, FCELL, 5099 rows 7647 columns, resolution: 0:00:00.17656 I thougth it was probably a problem with the dem resolution (5 m) but I tried with another DEM with different resolution and get the same error warning. Hope to solve this! Lara ___ grass-user mailing list grass-user@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/grass-user
