Hi GDAL devs,
I have a problem with GDALSuggestedWarpOutput producing an error. It works for
most of the files I've thrown at it, but I have one file that a user has sent
me for which the error occurs. The file in question can be downloaded for
testing at: https://dl.dropbox.com/u/12436846/715lkmaps.zip
My code and the output are below. GDALSuggestedWarpOutput produces the error:
"ERROR 1: Too many points (13924 out of 13924) failed to transform, unable to
compute output bounds."
Could somebody please explain how I can avoid this problem and warp the image
correctly?
Thanks,
Nik.
CODE:
------------------------------------
OSRImportFromEPSG(dstSRS, 3857 );
OSRExportToWkt( dstSRS, (char **)&pszDstWKT );
void *hTransformArg = GDALCreateGenImgProjTransformer( hSrcDS,
pszSrcWKT, NULL, pszDstWKT, FALSE, 0, 1 );
double adfDstGeoTransform[6];
int nPixels=0, nLines=0;
if ( GDALSuggestedWarpOutput( hSrcDS, GDALGenImgProjTransform,
hTransformArg, adfDstGeoTransform, &nPixels, &nLines ) != CE_None )
{
NSLog(@"Failed to get suggested warp output.");
return NO;
}
------------------------------------
OUTPUT:
------------------------------------
ERROR 1: Too many points (13924 out of 13924) failed to transform,
unable to compute output bounds.
Failed to get suggested warp output.
