I spend a considerable amount of time cleaning the 1 GSD orthomosaic. However, I often want lower resolution copies of the cleaned orthomosaic. Changing the resolution in Step 3 loses all the edits made on the 1 GSD ortho.
I have been successful in reducing the resolution in Photoshop, but the .tfw file does not properly place and scale the ortho properly. Is there a way to manually change the .tfw file (or metadata) for the reduced-resolution ortho so that it comes in properly. Below is an example of the info in the .tfw file.
