[GRASS-user] r.hazard.flood does not respect region settings?
Hi,
I'm testing r.hazard.flood and noticed that it computes the flood and
mti layers on the full region of the elevation raster instead of the
pre-defined region settings.
The relvant code I found from the r.hazard.flood is this:
# Detect cellsize of the DEM
info_region = grass.read_command('g.region', flags = 'p', rast =
'%s' % (r_elevation))
dict_region = grass.parse_key_val(info_region, ':')
resolution = (float(dict_region['nsres']) + float(dict_region['ewres']))/2
grass.message(Cellsize : %s % resolution)
Would it be possible to either respect the current region settings or
add a flag to choose between the dem region settings or current region
settings?

[GRASS-user] ps.map - eps frame affect/hide border and legend
Dear all, I'm trying to output a ps file with ps.map (GRASS 6.4.2). Results from the psmap.def are good, with border, colortable, vlegend, etc.. http://osgeo.codepad.org/NtM3oJy0 (pasted def file) But when I add an eps frame border, colortable and vlegend disappear. I changed the order, putting eps before or after the vlegend instruction, but without successful.

Hi Vaclav!!! lol!!! I'd wished!!! Just fixed it with awk :) Anyway, i tried what you suggested and didn't work in python 2.7.

Hi, could you post a bug in the trac system? an example made using one of the standard grass datasets (Spearfish or North Carolina) would help a lot too. is the eps file inside or outside the map frame? sometimes it helps to move it. the used-added eps file is just copied verbatim within the final output file; it might help to keep it simple or clean with eps2eps first? did you put a final 'end' after all the ps.map instructions? thanks, Hamish ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Would it be possible to either respect the current region settings or

if it needs to detect the original raster cell resolution (usually that's only
needed to avoid aliasing artifacts in certain situations) it should use r.info
to get the answer. I'm guessing due to the averaging of the ew and ns
resolutions avoiding aliasing isn't the case.
if a module wants to change the region (and almost none should ever do that
except for g.region by itself) it should set up a temporary WIND_OVERRIDE
first, in the case of python scripting there is an easy grass python function
to make that and clean it up at the end. (otherwise parallel jobs get their
regions messed up mid-run, and region changes without you expecting it will)
I suspect grass.raster's raster_info() is the better way for r.hazard.flood to
do what it's trying to do now. But also just querying the current g.region info
without changing anything is probably even better, as that is what the other
raster commands will expect to use. If the user should align perfectly with the
input map first, it should be noted in the help page for them to do it manually
before running the module.

Hamish
