Hi. I've used both for mapping. The DataPilot planning screen will tell you the GSD for each camera for an area to be mapped. The E50 will take many more photos at the same altitude, of fly higher for a less images but also less GSD.Has anyone used the E90 and E50 in mapping large flat roofs? I want accurate measurement ability. My question is could I lower the GSD by using the E50.
Thanks
Leland
