Hi, Thank you for the reply. Calls to GDALRasterIO() are OK. Which I assume in a line interleaved format look like this: GDALRasterIO(hBand, GF_Read, 0,0, i, j, pafScanline, nBlockXSize, nBlockYSize, GDT_Int16, 0, 0); Is t

Hi, I've shortened my questions to exactly this part of the code: // read datasets, compare data and write if ( (pafScanline2[j] > 6 || pafScanline3[j] > 950) && pafScanline[j] == 2) { GDALRasterIO( hDes
