OK, I know this can be done but of course. When originally did the step I thought, that was easy. However this aging prof didnt note the steps.
Here is the scenario .. i have 2000 image tiles (output from pix4d). The objective is to have an output vector layer "image tile key", the input would be the many image tiles. This would then enable a CAD to identify what image tiles to bring into CAD rather than choke on a 30 Gig orthomosaic.
