[Gvsig_english] Geoprocessing tools::strange error appears when trying to clip, intersect, ...

[Wolfgang Qual]

Hi Alvaro,
I first have to talk with my colleagues about giving away these datasets. But 
I had a closer look at the data using ogrinfo:

wqual at wolfgang:~$ ogrinfo /data/muc_daten_shapes/block.shp
ERROR 4: Unable to open /data/muc_daten_shapes/block.shp 
or /data/muc_daten_shapes/block.SHP.
Had to open data source read-only.
INFO: Open of `/data/muc_daten_shapes/block.shp'
using driver `ESRI Shapefile' successful.
1: block (3D Polygon)

So, it is a 3d-polygon theme. I remember umn mapserver and grass/QGIS having 
problems with this type of shapefile (or to be more exact, the gdal-library).

Therefore, I converted this shapefile into a "normal" 2d-Shapefile, using 
ogr2ogr:
wqual at wolfgang:~$ ogr2ogr -f "ESRI Shapefile" blockneu.shp -nlt 
POLYGON /data/muc_daten_shapes/block.shp

In the third step, I repeated the intersection. Again, no result shapefile was 
created, but the former error message did not appear again, but another one 
(or more within the information console of gvSIG):

Afterwards, I only selected some features of the input theme (the input theme 
is rather big) and calculated the intersection only for the selected 
features. Result: I got a nice result shapefile.

I have to say that I use a quite old pc for my testings at the moment. Would 
it help to run this on a newer machine? Or is it a problem with the 
java-application, which is independent from the power of my machine (what 
would be bad somehow...)?

Greetings,
Wolfgang
