Hi All,
Using Python + Gdal/OGR is there any efficient way of finding all the
polygons that contains the point X,Y ?
thanks ?

Hi,
This is most likely a minor issue, but it looks to me that the above
should not happen message always appears when gdal_translating a .vrt
file that refers to an .asc file. There are 2 GDALClose() for the .asc.

This is my try. Not the most efficient, but you could always use a
spatial index and a spatial filter:
Hi All,
I am trying to use Union function in OGRGeometry. But the unified geometry
is giving just a single point. So I am wondering what is going wrong??
Basically I want to join two geometry (can say disjoint) so as to have a
single geometry. So the method can compute the close points of those
Herman,
yes the warning was a minor annoyance but should not have caused any problem.
I've just pushed as fix in SVN so it doesn't appear in that situation. It's
linked to the caching mechanism behind VRTs that differ the opening of dataset
until real I/O is required. There are some
Hi Jose,
thanks for that. I've used SetSpatialFilterRect(x,y,x+0.01,y+0.01)

Hey all. I am having a problem with the geometry.Transform() method in
OGR for Python. Short version: geometry.Transform() returns a code 6. A
code 6, according to the OGR source is simply OGRERROR
II guess the rest is best explained by example:
from osgeo import ogr, osr
shapefile =
Probably I think I must use some different method to merge all the polygons.
Please help me finding out to do so.
Thanks in advance!
