Indoor Mapping & Wayfinding Automation
Production-focused engineering reference for floor plan parsing, indoor topology, wayfinding graphs, beacon/Wi-Fi positioning, accessibility routing, and Python automation pipelines.
About this site
Indoor mapping is not a flavor of outdoor GIS. Sub-meter precision, vertical topology, semantic enrichment, and deterministic routing pipelines all change the engineering surface area. This site is a production-focused reference for the engineers building those systems day to day.
Inside you will find runbooks for parsing native CAD (DWG/DXF), BIM (IFC), and SVG floor plans into validated, routable GeoJSON; coordinate-system patterns for multi-building campuses; Z-axis handling for elevators, escalators, and mezzanines; POI taxonomy design that survives contact with facilities reality; and the CI gating, schema validation, and rollback machinery that keeps deployed indoor maps trustworthy.
Every guide ships with annotated Python pulled from real pipelines — geopandas, shapely, networkx, ezdxf, rtree, pyproj — plus the validation, async batching, and SDK integration patterns that turn a one-off script into a service. The material targets facilities tech teams, GIS developers, indoor navigation teams, and Python automation builders.
Use the three colourful entry points above to jump into a section, or browse the topic cards below. Every page is offline-cached as a PWA, so you can keep the references with you on a site walk.
