Main objectives

To model trees in 3D urban environments, we have identified on the following main objectives:

  • Extracting tree meta-data from OpenStreetMap using cpr.

    • Position (latitude, longitude). In a park, boarding a road, etc.

    • Height, genus, species, crown diameter, circumference, etc.

  • Generating 3D tree models using CGAL and Gmsh.

    • LOD (Level Of Details) 0, 1, 2, 3.

    • Different leaf density.

  • Integrating tree models into the terrain mesh we already have.

    • Avoiding collision between trees and buildings.

    • Taking into account terrain elevation.

  • Optimizing and parallelizing the algorithms to efficiently handle large datasets.
