Elevation Data not accurate?
I am new to DD and want to know how I can get accurate elevation numbers. I did a flight for a piece of property that we are building a new building on. Right now it is only site work and one other existing building on the property. The map turned out great, although I flew at 80’ and now everything I am reading says fly higher. When I check elevation of the existing building it calculates about 11" lower than it is and the new building pad is calculated lower as well. Any suggestions on how to get this closer?
Also, is there anything out there that will give me elevations in relation to sea level not just AGL?

This is a very interesting app and I can see several possibilities for using this in my business.

Thanks! https://mydractgaming.com/forums/showthread.php?tid=412360
