About the Tree Density Calculator

The Tree Density Calculator is a QGIS plugin and command line interface package designed to calculate tree densities based on brightness images, using the local maximum of a sliding window.

The original Tree Density Calculator was written in C++ and ported to PyQGIS in 2018/2019. It has been developed in an open source environment to encourage further development of the tool.

The instruction pages can be found at <https://treedensitycalculator.readthedocs.io>.

The code repository can be found at https://bitbucket.org/kul-reseco/localmaxfilter.
