Perhaps a problem with the file permissions ?
After creating the tiles for level 0, the utility wants to create a
subdir called 1 and store the tiles for level 1 in this subdir.
Check this with your user. Make
mkdir 1
cd 1
touch test.tif
rm test.tif

Hi List,
I am using ogr via the python bindings to construct various polygons.
Here's just a simple question, to which someone might have some input. Is
there anyway to determine the topology, i.e. the number of holes, of a
polygon without e.g. having to export to WKT and examining the output
Simon,
You can use the OGRPolygon::getNumInteriorRings() method to get the number
of holes in an OGR polygon object.

You could use the `interiors` length in Shapely:
from osgeo import ogr
from shapely.wkb import loads
source = ogr.Open('my_polygons.shp')
layer = source.GetLayer()
feature = layer.GetNextFeature()
num = 0
while feature:
g = loads(feature.GetGeometryRef().ExportToWkb())
if g.geom_type ==

I'm sorry. I now see that this method is not exposed in the python bindings.
Not exactly. In fact you have to use the Geometry.GetGeometryCount() that
returns 1 (the exterior ring) + the number of interior rings. So
polygon.GetGeometryCount() - 1
Christian,
The permissions are OK. 1-8 subdirs are created as soon as the command
is launched. The program stops after generating 10-15% of the level0 tiles.

Thanks a lot. Didn't know that GetGeometryCount did that on polygons :-)
Cheers,

Perhaps there is a resource limit for the number of the files in a directory.
Try using
-useDirForEachRow
This builds another directory hierarchy with less files per directory.

Hi all,
As the message heading indicates, I am hoping to run a check within a
python script to determine if GDAL on a machine has been built with GEOS
support, and exit if it hasn't. Looking at inspect.getmembers( gdal )
suggests that I'm out of luck, but I wanted to confirm this.

Solved (I hope). Something I fail to mention in the first place: the
drive where the tiles are processed is mounted through sshfs (physically
the disk is incorporated in another server). After moving the data on a
local drive, gdal_retile.py passed, without error, the 4151 tile limit.
Hi,
My attempt to build gdal (trunk) on Windows with OpenJpeg failed with
these errors
C:\programs\GDALtrunk\gdal\frmtscd openjpeg nmake /nologo /f

Hi Joaquim,
In order to build with OpenJpeg, you must use the unreleased version 2.0
of OpenJpeg.
Try the following:
http://code.google.com/p/openjpeg/downloads/detail?name=openjpeg_v2_alpha_0.zip
