3D map data visualization on a limited geographical area for the Taxation Authority. Buildings and apartments were visualized and colored based on multiple parameters (data source, building use, building date etc.). Since the main purpose of the project was spotting the differences in data sources, we enabled a few additional filtering tools for this parameter (overlaps, not overlaps, isolate). With this concept, client’s workers are able to quickly detect if any of the apartments aren’t registered in one of the official registers data is coming from, so they can warn either institution that maintains the register or the apartment owner to report its property. The 3D map enabled apartments and floors stacking on top of each other.
