Web map is distorted in areas

Just want to make sure I am getting the best results I can for my web map. I have been flying a mission that covers about 150 acres of a city. Because of proximity to an airport I can only fly at 250 feet. I am limited also to the amount of time I can spend in the air so my overlap is 60/50 and speed is 22 -26 mph. The client doesn't need anything 3D, just a basic horizontal 2D look down. I have tried the 2D option with no success. My best maps are the regular DJI workflow, but I still get some warping of vertical structures and some of the parking space markings on ground as shown. Is this my best possible solution given the hard parameters above for the mission ? -JO

We are sorry to hear you are not happy with your results. Based on your Overlap Report and recent flight logs it looks like you are using roughly 50% overlap which is nowhere near enough to get reliable results.

50/60 overlap isn't going to do it either. 75/75 should be considered the bare minimum. 

You want that whole thing to be dark blue to get solid results. 

You are on the Elite plan so you can upload way more imagery than this without the need for additional points. 

The processing on the DJI and the Classic workflow is exactly the same. 

You don't really have any other option other than to use more overlap. Since you are using the Zoom you could use a wider field of view since that would give you more coverage with the same number of images.

Hey Zane,

Thanks for the guidance. Yep... I am limited by the time I can spend in the air and the height I can fly at so I think this is probably as good as it gets. I may try modifying the Zoom settings as you suggested. I have looked at some other examples here and the warping just looks to be a nornal factor of trying to look at vertical structures on a 2D map. If you think of anything else please feel free to let me know. -JO
