[GRASS-user] r.mapcalc(nulls into 0)
Hi, I am trying to do something really simple but not finding the right way to do it. I need to convert nulls into zeros. I have done this: *r.mapcalc raster2 = if(raster1 = null(), 0, raster1) * *r.mapcalc raster2 = if(raster1 == null(), 0, raster1) ** * But this convert all cells into nulls. I have tried another approach with r.reclass, rules: null/null()/no data/nodata...=0 1=1 2=2 3=2 4=2 5=2 No fun, all I get is an ERROR: null/null()/no data/nodata...=0 What I'm doing wrong?

[GRASS-user] Load PostGIS layer with tow geometry columns
Dear all, Trying to load a PostGIS layer with tow geometry columns it output's the following error: 'ERROR: Layer layer_name not available'. If one of the tow geometry's is dropped it works fine. Is there a way to define witch geometry I wont to load, something like 'geom_column=the_geom'? This is what I'm trying to do: *v.in.ogr dsn=PG:host=localhost dbname=bd_ceamsig user=postgres layer=sch_ambiente.escv_incendios_todos where=anyo=2009 output=temp* Thanks in advance!

Martin Thanks for your quick reply Martin, Actually it's not a format parameter that I miss but a parameter that would define which geometry I want to use in case there is more than one geometry per layer/postgis table. Example. In my table '*escv_incendios_todos'* I have tow filds/columns with geometry, one is called geom_23030 (coord. syst. epsg 23030) and the other geom_4258 (coord. syst. epsg 4258) and a trigger maintaining this tow geometry's synchronized. In the geometry_columns table there are tow entry's for the '*escv_incendios_todos' *table: 3970433;'';sch_ambiente;escv_incendios_todos;geom_23030;2;23030;MULTIPOLYGON 3970434;'';sch_ambiente;escv_incendios_todos;geom_4258;2;4258;MULTIPOLYGON So when I try to load '*escv_incendios_todos'* in GRASS there is no way to define which geometry I want to use. And the error 'ERROR: Layer layer_name not available' jumps out. By now I worked around by deleting the entry with the geometry I'm not interested on the geometry_columns table and then insert it again. Thanks.

Re: [GRASS-user] Retrieve pixel resolution using Python Script
Olá António Rocha,
This works for me, give it a try:
###
import os
try:
from osgeo import gdal
from osgeo import osr
except:
import gdal
import osr
def gdalinfo(pasta):
'''Le metadados com GDAL'''
ficheiros = os.listdir(pasta)
for ficheiro in ficheiros:
if ficheiro[-3:].lower() == 'tif':
# abrir imagem
filename = pasta+ficheiro
dataset = gdal.Open(filename, gdal.GA_ReadOnly)
if dataset is None:
print 'Nao foi possivel abrir a imagem %s!' % ficheiro
RasterXSize = dataset.RasterXSize
RasterYSize = dataset.RasterYSize
print RasterXSize,RasterYSize
print '\nfim'
return
gdalinfo('/home/eloi/Geo/raster/20790/')
###

If you use gdalinfo on an image, it will output the Pixel Size.
Hope that helps.
Mark
2010/6/28 António Rocha antonio.ro...@deimos.com.pt:
Greetings
I'm trying to retrieve an image (not yet imported to GRASS) pixel
resolution
through a Python Script but so far i was unable to figure out a method to
do
this. Is this possible? I have used g.proj to retrieve its projection and
datum but not the Pixel resolution.
THanks for your help
Best regards,
Antonio R.
