Hi, the GCPs are located in each image at known locations, you can create necessary files in a batch script:
- you have to create the group for each image (i.group) - you have to set the target and ref files for the group (i.target) - you have to create the POINTS file - manually try to rectify one image by hand and then see grassdata/LOCATION/MAPSET/group/GROUP/* however, if the position of GCPs is unknown to you, I'm affraid, you have to do it by hand jachym On Wed, Mar 25, 2009 at 03:04:43AM -0700, Petrone Orlando Mauro wrote: > > Hi to all, > I'm trying to use GRASS 6.4 (installed on UBUNTU) to realize a system to > automate the orthorectification process. > I have a group of little images (chip of 256x256 pixel) that I want to use to > orthorectify an image. > Can grass use the little chip to create the RPC polynomial without any > external action?
