Partial While the front-end and mortgage calculators are straightforward, aggregating Dutch cadastral datasets (BAG, WOZ, climate risk, 3D building models) requires integrating numerous specialized national APIs and GIS layers.
What it would actually take: Architecture requires a backend proxying Dutch public APIs (Kadaster, PDOK, CBS, WOZ-waardeloket) combined with GIS processing libraries (GDAL, PostGIS, Mapbox GL/Cesium for 3D CityJSON). The hard part is managing rate limits, authenticating with government open-data portals, handling complex geospatial bounding boxes, and parsing divergent proprietary XML/OGC data standards.
