Eli, I finally got around to looking at the example shapefile and running the same operation on my machine, and it does indeed seem like the same bug. Thanks for the good eye, this almost seems like two separate issues; first being the missing edge points and second being the weird offset. I

Hi all, Since a few people have shown an interest in helping out, I would suggest to set up space where we can post ideas, goals and test files.  This could take the form of one of the following: - a new wiki entry in trac, or the existing one at http://trac.osgeo.org/gdal/wiki/NetCDF - a fi

Jan, The first error message is because of the block size. The entire image is taken as a block; not good for large rasters. When copying, GDAL tries to load the entire block into the memory. It's very likely that the problem will be resolved if we create copies of the gtiffs with smaller blocks.

Jan you can skip that step and cut it up directly but it will take quite a bit longer. the wms driver will download the entire area each time you run gdal_translate -scrwin n n n n mywms.xml myouttile.tif also if your running into wms performance issues have you built overviews on your images? ht

Jan if you already have a wms setup with your data you could use the wms driver to read it. gdal_translate to a bigtiff. then cut it up into tiles with gdal_translate -srcwin Brian On Fri, 2011-08-26 at 15:17 +0200, Jan Tappenbeck wrote: > > hi! > > i have following problem. openstreetmap c

Etienne, My group is also very much in support of the suggested improvements, as NetCDF/CF is becoming the most important standard for data storage/exchange in our community (climate, meteorology, oceanography). My group is not much into GDAL driver development (at least not yet), but we are
