Post processing of tree height through reference measuring mechanism

[sebastiangaertner]

For the upcoming specifications on urban tree inventory tracking each tree should be able to be individually processed for its tree height. The online tool https://eleif.net/photo_measure.html can be taken as example. Images ready for the post processing will have to display a reference height stick already used in many tree monitoring activities.
