Cloud-optimized data transformation of Ministry of Justice maps XML and a simple WebGIS (What's this address now?)
summary
This presentation explains converting Japan’s Ministry of Justice cadastral XML (public maps) into cloud-optimized binary vector tiles (PMTiles) and hosting them for distribution. It covers the tooling and workflow used to mirror and transform raw XML into PMTiles (including creating PMTiles for drone GeoTIFFs), and building a simple, publicly available WebGIS using MapLibre GL JS to let users query “what lot number is here?”.
