[gdal-dev] Unions shapefiles using ogr

Hi all, How can I union several shapefiles into one using ogr? I tried using the OGR Virtual Format and created a XML file similar to this: source1.shp source2.shp My next step was to call ogr2ogr to created the new file. Th

Re: [gdal-dev] Unions shapefiles using ogr

Thanks Even. So this means I need to write my own application using the Union() from GEOS and I cannot use it on the command line using OGR VRT? That is OK, I can do that. Using existing utilities on the command line seemed easier ;) Thanks, Paul 2012/12/17 Even Rouault > Selon Paul Me

Hi Even, I'm not sure why I shouldn't use --format. If I can't use it why is it provided? Can I use --formats? Perhaps I should not handle this in my C#/WinForms but do this in our C++ core. I think we can make a method that would return what I need based on gcore/gdal_misc.cpp but that would rely

Re: [gdal-dev] does gdal support multiple simultaneous writers to raster

To add my 2cnts. With MapWindow GIS we use TauDEM binaries to perform watershed delineations. http://hydrology.usu.edu/taudem/taudem5.0/index.html These TauDEM binaries are optimized to use MPI, but also work if you don't have MPI installed. I don't know in detail how it works but in general you

[gdal-dev] Converting ecw to tif for Geoserver

The last days I've been trying to convert my ecw file to a GeoTiff so I can use it in Geoserver. The ecw is a mozaik of aerial photos. When I do these two commands it is working in Geoserver: - gdal_translate -of GTiff -co tiled=yes -co compress=jpeg -co photometric=YCBCR -a_srs EPSG:28992 -

Re: [gdal-dev] Converting ecw to tif for Geoserver

Did I loose it along the way? Or is it expected to have such a large sized end result. Because it is now so large I think I'll get into trouble when I add it to Geoserver. I hoped to use the tiff directly and not use Geoserver's pyramid plug-in. Thanks, Paul 2013/2/9 Paul Meems &g

Re: [gdal-dev] Converting ecw to tif for Geoserver

Thanks Andrea, I didn't understand that the first time. So there is no way to have the raster on top of another layer without getting white areas? In that case I will upload the smaller tiff file ;) -- Paul 2013/2/10 Andrea Aime > On Sun, Feb 10, 2013 at 8:30 PM, Paul Meems wrote
