We have a trial version of Drone2map.  We are testing it for our 911 folks and they are asking what is the optimum overlap.  I found some info that says 70%  all around.  Is this standard?   We are new to the world of drones  and not much experience with drone software.  Thanks,  Steve

I would advise 70% or more, and note if you have tall features (trees, buildings) you should consider overlapping imagery at the top of those features, not just on the ground.

In general my advice is very often to fly higher.  I find most people testing drones are excited by the prospect of 1 cm imagery, but flying too close to the ground generates a lot of problems with oblique views of trees/buildings, ground blur, excessive data volumes,  etc.  

For any project, even if you decide you want to fly at 200' altitude, I'd recommend an additional flight up at 400'  You might find 6 or 8 cm imagery works very well and it will process much faster
