[gdal-dev] GDAL-processing center
Hi! I would like some feedback on creating a GDAL-processing center. What I want to achieve is the following: - 1 server running a webserver with GDAL and everything installed on it. This can be accessed by other machines through a local network with for instance http://LOCALIP/GDALPROCESSING. - I want any browser to go to that webpage and give access to it`s computer resources. When jobs are added they should be distributed to the connected computers. So the processing is local on each computer Do you have any recommendations on software-combinations (free) to start to be able to do this, or are there some limitations (on the browsers etc) that makes it impossible to do this processing locally on some machines?

[gdal-dev] GDALWarpOperation.ChunkAndWarpImage slow on large tiffs
Hi, GDALWarpOperation.ChunkAndWarpImage was reported to be extremly slow on larger geotiff (over 1GB). Is it possible that it is much slower with respect to GDALRasterIO() even without reprojection? Should I return to 'manualy' reading data via GDALRasterIO() + fidling with data extents and cells alignement? I thought that GDAL ChunkAndWarpImage will do it even faster, possibly knowing better (?) various formats nature. Is there way to tune somehow performance? Currently no reprojection and GRA_NearestNeighbour. Still the same code which I posted before http://trac.osgeo.org/qgis/browser/trunk/qgis/src/providers/gdal/qgsgdalprovider.cpp?rev=15400#L625 Thanks for help.

Re: [gdal-dev] GDALWarpOperation.ChunkAndWarpImage on source without CRS
Le mercredi 09 mars 2011 12:25:47, Radim Blazek a écrit : Radim, I don't see anything obviously wrong in your code, but the warping API is admitedly quite tricky to use. The closest code in GDAL that you could take insipiration from is perhaps GDALReprojectImage() in alg/gdalwarper.cpp that does pretty similar things to your code (apps/gdalwarp.cpp does similar things too but perhaps a bit less clear to follow). 1) The cause of the crash is the pTransformArg=0x0 passed to GDALGenImgProjTransform () which causes a null pointer deferencing when doing psInfo-pDstGCPTransformArg. I'm surprised that it crashes here and not the line before where the psInfo is already deferenced (is your GDAL build with - O2 ? If yes, you should perhaps rebuild it without it). I don't either understand how you get a null pointer at that point. I don't either understand why the fact that the source dataset has a SRS or not has an impact at that point... Stepping in the code with a debugger might help to track where that null pointer comes from. (the line numbers didn't match the ones of my copy so I suspect you're not using GDAL 1.8.0, but that shouldn't be an issue however) 2) Yes, indeed pDstGCPTransformArg is unused. So there's perhaps some code cleaning possible inside GDAL here, but that's unlikely to cause a problem per se. 3) You should check the return value of myOperation.Initialize( myWarpOptions ). If the validation of the warp options failed, it would be unsafe to go on with the warping itself. 4) myMemDsn.sprintf( MEM:::DATAPOINTER=%lu,PIXELS=%d,LINES=%d,BANDS=1,DATATYPE=%s,PIXELOFFSET=0,LINEOFFSET=0,BANDOFFSET=0, ( long )theBlock, thePixelWidth, thePixelHeight, GDALGetDataTypeName(( GDALDataType )mGdalDataType[theBandNo-1] ) ); is dangerous. I think it will not work for a Win64 build where pointers are 64 bits but long is still 32 bit. You could use the CPLPrintPointer() function from GDAL to format it : char szPointer[64]; memset( szPointer, 0, sizeof(szPointer) ); CPLPrintPointer( szPointer, theBlock, sizeof(szPointer) ); Best regards, Even Hi, I am using GDALWarpOperation.ChunkAndWarpImage to read data, everything works well except when a source dataset does not have a CRS defined.

Currently no reprojection and GRA_NearestNeighbour. Radim, GDALWarpOperation is intended to be a high precision image resampler. Within the constraints of doing this correctly it attempts to be fast, but it will generally be quite a bit slower than direct RasterIO calls and in some situations dramatically slower. Particularly it is completely inappropriate to use for radical downsampling.

Re: [gdal-dev] GDALWarpOperation.ChunkAndWarpImage on source without CRS
Hi, thank you a lot for your help and recommendations. The problem seems to be in GDALCreateGenImgProjTransformer2 in the block which begins on line 1072 (alg/gdaltransformer.cpp) current trunk: else if( (pszMethod == NULL || EQUAL(pszMethod,GEOTRANSFORM)) GDALGetGeoTransform( hSrcDS, psInfo-adfSrcGeoTransform ) == CE_None (psInfo-adfSrcGeoTransform[0] != 0.0 || psInfo-adfSrcGeoTransform[1] != 1.0 || psInfo-adfSrcGeoTransform[2] != 0.0 || psInfo-adfSrcGeoTransform[3] != 0.0 || psInfo-adfSrcGeoTransform[4] != 0.0 || ABS(psInfo-adfSrcGeoTransform[5]) != 1.0) ) here it excludes all source data sources which are not georeferenced. If I comment the psInfo-adfSrcGeoTransform check, everything works OK. Is there a good reason to not allow to transform images which are not georeferenced? I can get around also setting for example psInfo-adfSrcGeoTransform[0] = 0.0001; in my code, but that is not nice of course. Is there a better workaround?

So there's perhaps some code cleaning possible inside GDAL here, but that's unlikely to cause a problem per se. 3) You should check the return value of myOperation.Initialize( myWarpOptions ). If the validation of the warp options failed, it would be unsafe to go on with the warping itself. 4) myMemDsn.sprintf( MEM:::DATAPOINTER=%lu,PIXELS=%d,LINES=%d,BANDS=1,DATATYPE=%s,PIXELOFFSET=0,LINEOFFSET=0,BANDOFFSET=0, ( long )theBlock, thePixelWidth, thePixelHeight, GDALGetDataTypeName(( GDALDataType )mGdalDataType[theBandNo-1] ) ); is dangerous. I think it will not work for a Win64 build where pointers are 64 bits but long is still 32 bit. You could use the CPLPrintPointer() function from GDAL to format it : char szPointer[64]; memset( szPointer, 0, sizeof(szPointer) ); CPLPrintPointer( szPointer, theBlock, sizeof(szPointer) ); Best regards, Even Hi, I am using GDALWarpOperation.ChunkAndWarpImage to read data, everything works well except when a source dataset does not have a CRS defined.

Re: [gdal-dev] GDALWarpOperation.ChunkAndWarpImage slow on large tiffs
Hi, yes that is the mail reporting the error. Thank you for explanation.

If yes, then the report gives an interesting hint. You must be aware that the warping code does not take advantage of overviews (it is intended to operate on the full-resolution raster, and not for downsampling as Frank underlined), so you will have really bad performance comparing too GDALRasterIO() if the output dimensions are much smaller than the input window size. GDALWarpOperation.ChunkAndWarpImage was reported to be extremly slow on larger geotiff (over 1GB). Is it possible that it is much slower with respect to GDALRasterIO() even without reprojection? Should I return to 'manualy' reading data via GDALRasterIO() + fidling with data extents and cells alignement? I thought that GDAL ChunkAndWarpImage will do it even faster, possibly knowing better (?) various formats nature. Is there way to tune somehow performance? Currently no reprojection and GRA_NearestNeighbour. Still the same code which I posted before http://trac.osgeo.org/qgis/browser/trunk/qgis/src/providers/gdal/qgsgdalpro vider.cpp?rev=15400#L625 Thanks for help.

Wendell, I think gdalwarp with -crop_to_cutline and a cutline specified with the shape will accomplish what you want. http://www.gdal.org/gdalwarp.html The cutline comes from an OGR supported file but this can be as simple as a .csv file with a WKT geometry in it. The -crop_to_cutline may be new to 1.8. Best regards, Wendell, Please be aware that this method may introduce raster shifting and possibly resampling (depending on the original cell size). It might or might not matter for your purposes. A better approach is to use gdal_translate with -projwin to extract to shape envelope and then gdal_rasterize with -i to burn nodata where shape is missing. -marius ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev

Re: [gdal-dev] how to build gdal with oracle spatial
Natasha, OSGeo4W has the Oracle-10g plugin for GDAL. You can use the GDAL package from it too.

Re: [gdal-dev] how to build gdal with oracle spatial
Natasha, I do not believe FWTools to have the Oracle driver built in, so that you may have to build it from source, having first installed the Orcale client libraries (free download from Oracle - this also includes the Oracle ODBC driver, which you will need if you want to connect to Oracle using ODBC). Alternatively, can you use OSGeo4w as previously suggested?

[gdal-dev] Polygonize and 8CONNECTED
Hi all, I was writing to enquire about the status of the 8CONNECTED=8 option in the Polygonize function of GDAL 1.8. I would expect that this option joins all pixels of equal value that are diagonally adjacent into a single polygon. However, with the following raster dataset (see http://i.imgur.com/jdUla.png) I receive two polygons in my output shapefile (see http://i.imgur.com/CZWMU.png ). For a copy of the raster, see http://dl.dropbox.com/u/6732375/mish9000.img.zip I am calling polygonize from GDAL's python bindings, which reports itself as GDAL 1.8.0, released 2011/01/12. My code looks like: gdal.Polygonize(tmprasterband, tmprasterband, shapefile_polygons_layer, 0, [8CONNECTED=8]) Is this the expected behaviour or a bug? Can I modify my call to polygonize to get the desired behaviour? If not, how would I merge multiple polygons with the same attribute value (an id number) into a single geometry?
