This question already has an answer here:
Are you aware of any way to crop a geotiff while maintaining the co-ordinate information?
I am trying to crop a series of geotiffs of multi-beam data which have a black frame on one or two edges (in arcmap 10) which i can't remove, even setting the background colour to no colour does't work (it is set so that only the multibeam image is showing though).
Im not actually a 100% sure what the marks are, the data was worked in fledermaus to create DTM's and exported as geotiffs then to arc .
I've read the other entries about this problem but i not really confident on how to use gdal or code. I no longer have access to fledermaus so cannot re-edit etc.
