@mshirley, I have updated my answer with a script which uses the QgsMapToolEmitPoint subclass to give you a somewhat visual approach to aligning rasters. I hope it helps you. Let me know how it goes.

I ended up writing almost the same code with the only difference being a call to shutil.copyfile() first followed by changing the geotransform on the new file in place. Your method is better, and I'll change my code. To use this solution, I repeatedly loaded and unloaded my rasters, guessing at the offsets and re-running the python code. I'm still hoping for a solution within QGIS that involves dragging the raster in some way that gives immediate feedback as the user matches features visually. That would be much quicker. | |
