Measuring Heights

[Mymgb]

I live in an area with very tall Southern Pine trees and when trying to calculate a mission of Waypoints in Litchi, I have been “gestimating”
and holding my breath that I have cleared these trees. Most times I over-estimate just to be sure which often makes me re-work my mission. However, I have found a free app in the iOS USA App Store called Object Height. (See attached) I have checked objects close to my reach and it has proven to be very accurate but not exact. If anyone has found a better solution I hope you will share it. Example: on an 8 ft object it calculated 7ft 8.5inches. Works with ft,inches or cm.i don’t know if it is available worldwide

Similar is available on Android. I'll see how it works.

One more thing to buy and carry ... Where I am *most* of the trees are in to 70-100 ft range. There are a few outliers that the loggers missed but a 40m RTH altitude will pretty much clear everything.

You can set RTH alt in flight: go higher than highmost trees, set RTH alt, done.

Thats what I do. fly up to the highest tree or object and add 50 '
