Re: [gdal-dev] Re: org2ogr, KML, and srs definition

Brent, to use that experimental feature (available in 1.9.0), you need to set GDAL_FIX_ESRI_WKT=TOWGS84 Try the following: GDAL_FIX_ESRI_WKT=TOWGS84 gdalsrsinfo yourfile.shp If you see the towgs84 parameters in the PROJ.4 string, then it will work with ogr2ogr. This is documented in

[gdal-dev] Creating NITF with GCPs

Hi I'm trying to write an NITF image where the geo-registration is with 4 GCPs. Is this functionality supported by the NITF driver? Looking through the code it seems that there is no way to create the IGEOLO data to the NITF from the supplied GCPs, but rather it will always calculate the

[gdal-dev] GEOS geometries SRS not set

It appears that when new OGR geometries are created using the spatial operations features of GEOS via OGR methods like ConvexHull, Buffer, etc. that the spatial reference of the newly created OGR geometry is not assigned. Is this by design or is it an oversight? If by design, what was the

Thanks Even. We haven't made the switch to 1.9 yet. I will add it to our 1.8.1. Do you see any problems with that? Sent from my mobile - From: Even Rouault Subject: Re: [gdal-dev] Creating NITF with GCPs Date: 20 פברואר 2012 21:20 Le lundi 20 février 2012

[gdal-dev] gdal / mapserver draw failure

[gdal-dev] nmake.opt compile rule changes

Folks, If you don't build on Windows using visual studio NMAKE files you can stop reading. I have removed the .cc.obj and .c.obj rules from the nmake.opt and ensured that CPPFLAGS gets set so that the default NMAKE rules for compiling can get used. The advantage of this is that they will build
