[GRASS-user] convert many files together at once
Hi, is there any option so I can convert many files or a folder (for example, 500 images from .asc to .tif) together at once, so that they will have matching color analysis? I use to do this untill now with Globalmapper, the batch convert/reproject option and I would like to do it through Grass or another open source gis program. Thank you. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Re: [GRASS-user] convert many files together at once
There are several options. You could do a shell script to import all files in grass (very easy in linux) or I believe grass gui has a batch import feature. Also, QGis has a gdal plugin that will let you convert several files at once (I think it's in raster / gdaltools / transform). To set the same color for all rasters, once in grass you can see what is your high and low value and set the correct color for one of the rasters. Then you just use r.colors to copy the colortable from one raster to all the rest. cheers Daniel On Fri, May 11, 2012 at 5:23 AM, giannis Nj netsag...@hotmail.com wrote: Hi, is there any option so I can convert many files or a folder (for example, 500 images from .asc to .tif) together at once, so that they will have matching color analysis?

[GRASS-user] r.finder
dear all, I recently published a grass script for focussing surveys. The name is r.finder, hoping it can be of help for somebody... you can find it at: www.palombini.net/sw/finder with explanations, manual and a brief tutorial (the script purposes summary is copied below) All the bestAgu - r.finder by Augusto Palombini r.finder is a GRASS-GIS script created for the intelligent geographic survey, in order to check the analogies of the places where some known items are located and show the most similar areas in the region. r.finder outs a map containing all cells matching the same combination of thematic maps parameters of the non-null/non-zero cells in the input map. May out as well a statistical report and graphs of the cell values. o Dr Augusto Palombini PhD www.palombini.net - archeologo - archaeologist - ricercatore - researcher CNR (National Research Council of Italy)ITABC - Institute for Technologies applied to Cultural Heritage Virtual Heritage Lab http://www.vhlab.itabc.cnr.it (+39) 06 90672721 - 06 90672448o ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

r.finder, hoping it can be of help for somebody...
Augusto, great news :) I'll test it in my geomorphological work surely. You
would not want to add it to GRASS-Addons wiki page (
http://grass.osgeo.org/wiki/GRASS_AddOns)?
One note: in GRASS shell scripts it's usually better to use:
-- module g.message instead of standard echo
-- special temp files (made with g.tempfile):
# create temporary file
TMP1=$(g.tempfile pid=$$)
if [ $? -ne 0 ] || [ -z $TMP1 ] ; then
g.message -e ERROR: Unable to create temporary files.
exit 1
fi
-- cleanup function and some actions for the case of user exit
cleanup()
{
g.mremove -f vect=MY_TEMP_VECTOR --q
rm -f $TMP1*
}
## what to do in case of user break:
exitprocedure()
{
echo User break!
cleanup
exit 1
}
## shell check for user break (signal list: trap -l)
trap exitprocedure 2 3 15
