When I do "gdal_merge -o result.tif bottom.tif top.tif" I get the following error:
ERROR 3: result.tif: Free disk space available is 1011663560704 bytes, whereas 61588097799713184 are at least necessary. You can disable this check by defining the CHECK_DISK_FREE_SPACE configuration option to FALSE. Creation failed, terminating gdal_merge. I don't understand. The two TIFs I'm trying to merge are 1.27GB and 64MB and it's saying 61588097799713184 bytes are needed? That's 61.58 PB. Why would gdal_merge think it'd need 61.58 PB?
