In *2024* this project has received funding from Kadaster, the Netherlands' Cadastre, Land Registry and Mapping Agency.

Prior to 2024 the building reconstruction algorithms were developed as part of *Geoflow* and the *gfp-building-reconstruction plugin*. During the summer of 2024 the code was refactored and the *roofer* project was born.

:alt: The roofer reconsruction algorithm

The roofer building reconstruction algorithm is largely data-driven, so the quality of the result depends on the quality of the input data. The following parameters can be tuned to optimise the performance for a given point cloud.
