Hej List, I was using gdal1.10_dev (precompiled from gisinternals.com/sdk) to warp a quite large ECW image, but after running for a few days the process crashed with an integer overflow error:
C:\Users\simlk\Downloads\release-1600-x64-gdal-mapserver>gdalwarp -s_srs "+proj= etmerc +ellps=GRS80 +lat_0=0 +lon_0=-39 +k_0= 0.9996 +towgs84=0,0,0,0,0,0,0 +uni ts=m +no_defs" -t_srs "EPSG:4747" -of GTiff -co "BIGTIFF=IF_NEEDED" -ts 110000 3 00000 -wm 3072 C:\Ortofoto\GR_samlet_ny.ecw T:\TEMP\simlk\out.tiff Creating output file that is 110000P x 300000L. Processing input file C:\Ortofoto\GR_samlet_ny.ecw. 0...10...20...30...40...50...60...70...ERROR 1: Integer overflow : nDstXSize=275 00, nDstYSize=37500 I was trying to mimic a utm zone 24 projection in my source srs - and yes I did forget the false easting +x_0=500000, but I doubt the problem is related to that. Is there some other creation option that I missed for huge output? Cheers, Simon Kokkendorff, National Geodata Agency of Denmark
