Enhancing population localization through assignement of buildings to census grids

Dynamic spatial microsimulations project individuals over time and space. The German model Mikrosim currently represents populations at the regional level but would benefit from assigning households to individual buildings. As no complete building database exists, data from multiple sources must be combined to build a coherent dataset of building locations, areas, and capacities. We model the geo-referencing of buildings to census grids under constraints as an optimization problem and present mathematical formulations and solution approaches.
