The problem seems to have been related to the presence of a .prj file with the .shp file.
using the command gdalwarp -cutline .\shp -cl allROIs -cwhere "Item = 1642" .\1642\1642.bmp .\1642.tif seems to fail to compute cutline bounding box when there is a .prj file present for the .shp and the target image has no georeference embeded as with a geotiff. Here in this case I was trying to trim a .bmp so that was that I think was the reason. However remove the .prj from the .\shp directory and it works! Alternatively, I can specify the -s_srs and -t_srs as the same and this also works although it does throw a warning that the input vector layer has an srs while the raster does not. As long as the two are in the same projection. No problem I think. -Dan -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Using-gdalwarp-to-effectively-trim-an-image-tp4621161p4628208.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
