Hemispherical photography (HP) is a wide-spread method for assessing the canopy characteristics and light regime in a forest. In the following paper that we just published on Ecology and Evolution, we evaluated if such method can be carried out with smartphones equipped with (small and cheap) fish-eye lens. The answer: yes!
Please have a look here:

Thanks to a fellow researcher, I recently discovered this app:
- What does it do?
“HabitApp is designed for aiding habitat assessment in the field, providing a simple way to measure the leaf coverage provided by the surrounding tree canopy.”
- Did I find it reliable?
- Did I find it useful for research purposes?
- Did I find it comparable with professional software/instruments to evaluate canopy characteristics?
- In a sort of way. More of this to come soon!
My advice is to download it and use it in your forest assessments! More feedback to the developers can help to improve it.
