[gdal-dev] [WKTRaster] WKT Raster band to GDAL band

Hello, I've created a WKTRasterBand-to-GDALRasterBand conversor, in the frame of WKT Raster project. I'm not sure if the results are correct. You can get the code from here https://svn.osgeo.org/postgis/spike/wktraster/rt_core/rt_api.c, but basically, the steps are: 1.- Register GDAL/OGR drivers

Re: [gdal-dev] Re: gdal_translate not working/ windows 7 64bit?

Chris, gdal_translate requires selection of a subdataset if the NetCDF file has more than one subdataset. Either specify which subdataset you want, or use -sds for all of them as Tamas did. I don't know if that will solve your problem. kss -Kyle On Fri, Mar 5, 2010 at 3:01 PM, ggp08ctl wrote

[gdal-dev] Re: gdal_translate not working/ windows 7 64bit?

Hi Tamas, Thanks for replying. Alas, I am not terribly able when it comes to binaries and compiling programs (hence my use of osgeo4w). I have just downloaded a *.nc file from another source altogether, to try. I get the same problem, so I don't think it is specific to the gebco data. The file is

Re: [gdal-dev] gdal_translate not working/ windows 7 64bit?

Hi Chris, While I'm no aware of any specific issues related to Win7 if you provide some test data I could try your command on my Win7 x64. So as to make sure about the problem you might also want to test with the binaries available at http://vbkto.dyndns.org/sdk/ (Run sdkshell.bat for the command

Re: [gdal-dev] Georeferencing Geostationnary (+proj=geos)

So, as far as I understand: GDAL can reference image with geos projection like +proj=geos +lon_0=42 +h=35785831 +datum=WGS84 GDAL can put GeoTransformation information like -a_ullr -924124.2 5421728.5 4179561.6 3468466.1 I guess this is related to maxium / minimum latitude and longi

Re: [gdal-dev] faster way to display shapeFile

Hi Pawell, A shapefile is not usually spatially indexed, and ogr cannot use the ESRI index anyway, so the entire dataset is read every time to plot it. For a large shapefile this is considerable overhead, especially when you are zoomed in & only want to render a small region. See the info her

[gdal-dev] gdal_translate not working/ windows 7 64bit?

Hi all, I have used gdal before (very briefly) to translate gebco bathemetry data from the netcdf file it comes as, into a tif format that I can use/ further convert in esri arcgis software. When I used gdal before (on another system) I used the osgeo4w windows version on 64bit vista, and simply

Hi, You might wan't to make a test with the packages available at: http://vbkto.dyndns.org/sdk/ All of those gave geos support compiled in. By downloading the SDK pacakges your could also compile gdal by yourself easily using a VS Command Prompt and type 'nmake gdal' in the SDK root directory.

Hello, I would like to build and use OGR with GEOS support on Windows XP 32 bit using Visual Basic.NET (.NET framework 2.0 or 3.5). GDAL/OGR 1.7.1 and GEOS 2.3.0 compilation seem to work fine (using nmake, Visual Studio 2008, only warnings, no error messages). I used the following GDAL/OGR nmake

Re: [gdal-dev] SetSpatialFilter not working?

That makes sense. I was using FTools so perhaps the GEOS support is not built in? Anyway, I ran it on my Linux box and the analysis part works fine. However, the features that it identifies for deletion don't actually get deleted so the file remains unchanged. (code included at bottom) Th

Using the Python-script I was able to update the SetGeoTransform and SetProjection with success. I have also done the same with a VB-script with the same result. I do not see anything wrong in the header and the file itself opens without errors. Thanks for the warning regarding bugs in the libtiff
