This web page gives all ressources to participate to the LoD2 building reconstruction from aerial lidar benchmark, with a focus on robust methods able to handle country scale reconstruction

Paper

The benchmark is extensively described in this paper: (link to be given when paper is published)

Benchmark areas

The benchmark consists of 4 areas. On each area, the input data consists in an IGN LidarHD tile, and manually constructed building footprints:

• • Peri-urban 1: Lidar tile   footprints

  • Peri urban 2: Lidar tile   footprints

  • Urban 1: Lidar tile   footprints

  • Urban 2: Lidar tile   footprints

Participate to the benchmark

• • Run your reconstruction method on the 4 areas

  • Send your results as 4 CityJSON files to lod2bench@ign.fr

Results of the benchmark

The results of the methods evaluated in the paper and of new participants are given below:
