Peter, Please create a new ticket at http://trac.osgeo.org/gdal/newticket and attach your code. If all goes smoothly, it will be added into the 1.8 branch of GDAL and released with GDAL-1.8.0 On Tue, Aug 3, 2010 at 12:20 AM, Peter Baumann < p.baum...@jacobs-university.de> wrote: > Dear GDAL main

[gdal-dev] new GDAL driver: how to proceed?

2010-08-02 Thread Peter Baumann
Dear GDAL maintainers, we have written a GDAL driver to add the rasdaman database as another "data format" that GDAL can read, and we would like to contribute this to the GDAL project. Rasdaman is a raster database middleware offering an SQL-style query language on multi-dimensional arrays o

2010-08-02 Thread Manuel Massing
Hi Lance, I suspect the most probable cause for the transform failure is a non- invertible geotransform matrix in CSTrans (i.e., due to incorrectly set scale values). What are m_srcGT / m_dstGT set to (the 6 actual values, not the code fragment used to set them)? m_srcGT should be set to the sou

[gdal-dev] WMS overlapping tiles

2010-08-02 Thread Carlo A. Bertelli (Charta s.r.l.)
Hello, JOSM wms and the fairly simplistic Grass r.in.wms allow tile overlapping which is sometimes very useful when checking map consistency and trying to spot digitizing errors. I didn't find this option nor in the xml definition nor in gdal_translate. I imagine it could be feasible with an approp
