<div style="direction: ltr;">Hello everybody,</div>
<div style="direction: ltr;"> </div>
<div style="direction: ltr;">I'm experiencing some problems with the
GDAL tools package on Quantun Thetys (1.5.0). When I try to run the
applications of GDAL tools (any of them) I recieve a error message,
first: "gdal(name of app).exe stopped working" and then another one:
"The process was interrupted some time after starting successfully".
Somebody knows how to solve this problem? </div>

Very large layers? Enough memory in the computer?<br>

<div style="direction: ltr;">I also have other question, any of you
could please tell me how to cut a shp in a different extent (smaller)
and then convert it into raster? Thank you in advance.<br>

For clipping, two ways come to mind. The GDAL utility ogr2ogr has an
option -clipsrc. Here you specify the xmin, ymin, xmax and ymax
bounding box. So something like:<br>
ogr2ogr -clipsrc 200000 500000 210000 510000 original.shp clipped.shp<br>
<br>
Alternatively, if you create a polygon shapefile identical to your new
extent, then in QGIS select Vector->Geoprocessing Tools->Clip.
This will "cookie cut" your original with the extent polygon.<br>
<br>
Converting to raster is a different issue altogether. If you want to
interpolate between vector features, then you have to choose the
interpolation method and parameters. If you simply want raster cells to
have some value from the shape features, and NULL everywhere else, then
you can use the v.to.rast modules from the GRASS plugin. <br>
