Good Day List!
We are working on a project that involves cross-referencing gcp chips between two satalite images. The chip is a small image extracted in such a way that the GCP is located at the center, usually a few pixels in size. We have two images as input, a raw (unprocessed) image, and an orthorectified image of the same area. What I need to do now, is to project the chip found on the orthorectified image, so that it resembles the area on the raw image in order to do cross referencing. Originally, I considered using the Ossim library for this purpose, but recently had to change to using GDAL for the projections. I am not familiar with the GDAL library at all, and I'm finding it difficult to identify exactly what classes I need to be looking at. It is important to note that we do not have the projection information when running the program, we need to determine the required information from the metadata of the image. Could someone please guide me in the right direction, or perhaps explain to me how I would go about this process? I am fairly new with this line of work, so I apologize for any inconvenience caused. Thank you for your time and efforts! Francois Francois Maass B.IT University of Pretoria Cell: 072 397 0294 Email: [email protected]
