I am trying to create an orthomosaic of a large area photographed with a MicaSense 5 band Rededge camera. The process crashed with the above error. I have tried with not merging the orthomosaic tiles and they are created. I do not have a problem with merging tiles of the DTM or DSM. They work fine. I have tried processing a much smaller area (16 5 band images)and (8 5 band images). These do not work either. They end with the same create tile reader error.
I am using Drone2Map for ArcGIS.
I have tried with Pix4d Mapper Pro with the same result.
Since the orthomosaic tiles are created, I am puzzled as to why a final merged product can not be created.
