[gdal-dev] RPC and DEM = Too many points (441 out of 441) failed to transform

Hi, I've seen that there are quite a lot of messages on this problem, but none of them helped. When running the following command: gdalwarp -rpc raw.tif out.tif with a raw.tif and raw.rpb file, the image "orthorectifies" correctly. The moment I run: gdalwarp -rpc -to RPC_DEM

[gdal-dev] Remove projection info

Hi all, I'm looking for a way to remove any projection and CRS information from an image. I've tried: gdal_translate -a_srs "" in.tif out.tif but without any success. Does anyone know how to do this (or by using CreateCopy() via source code)? Thanks _

[gdal-dev] Merge images without coordinates

Hi all This is maybe not the right place to ask, but since gdal provides merge functionality, this is the place to start. gdal_merge provides functionality to merge images with coordinates. I now want to merge images WITHOUT any coordinates, hence do a pixel-by-pixel matching. I will be able to i

[gdal-dev] Writing raster - 0 in every even column

Hi all I have a strange problem when writing to a GDAL dataset. I'm currently doing the following: *GDALDataset *mInputDataset = (GDALDataset*) GDALOpen("in.tif", GA_ReadOnly); GDALDataType type = mInputDataset->GetRasterBand(1)->GetRasterDataType(); int mWidth = mInputDataset->GetRasterXSize();
