Even, Thanks for pointing me to the API documentation (which i had seen) and the python unit tests (which i had not - very interesting!) Unfortunately, neither shows the SetVertCS method actually being called.
Thanksfully, this is the open source world :), so i am able to step through OGR's internal methods (like SetEPSGVertCS) with a debugger to guess how they actually work / should be called. I have now done a fair bit of study of the source, and GDAL's .csv data files, and have some idea of the state of things. I'll describe my findings in a new thread. -Ben > -----Original Message----- > From: Even Rouault [mailto:even.roua...@mines-paris.org] > Sent: Tuesday, August 23, 2011 11:33 AM > To: gdal-dev@lists.osgeo.org > Cc: Ben Discoe; 'Rodolfo Bonnin' > Subject: Re: [gdal-dev] Geocentric Coordinate System Support > > Le mardi 23 août 2011 19:28:49, Ben Discoe a écrit : > > > My question is how > > the geocentric support and vertical datums are supposed to work, e.g. what > > are valid arguments to SetVertCS which can produce a valid result when > > transforming from geocentric? > > Several links that may help you : > > http://gdal.org/ogr/classOGRSpatialReference.html#1c8d3eaf2751d9912797c75f47 7549fe > http://gdal.org/ogr/classOGRSpatialReference.html#4764cca1641b045a63afa95d01 922add > http://gdal.org/ogr/classOGRSpatialReference.html#6cb94a55501d2444b9f93eacd8 ff0411 > http://trac.osgeo.org/gdal/browser/trunk/autotest/osr/osr_basic.py > http://trac.osgeo.org/gdal/browser/trunk/autotest/osr/osr_compd.py _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
