Job Post: GIS Developer + Full-Stack Engineer for Land Records + Maps MVP (Ahmedabad District) Project Overview I am building a pilot application that allows users to stand on a piece of land in Ahmedabad District (Gujarat, India) and instantly view its land parcel details (survey number / 7/12 extract reference) on a map. I already have village cadastral maps in PDF format. The goal is to convert these into map overlays, integrate them with Google Maps (or open-source alternatives like Mapbox/MapLibre), and build a simple app (mobile/web) that shows the land parcel when the user shares their GPS location. Phase 1 (Pilot Scope – 5 Villages) 1. GIS Data Processing Convert village cadastral maps (PDF) into usable geospatial format. If raster → georeference with known landmarks (roads, rivers, boundaries). Export as GeoJSON / Shapefile / PostGIS-compatible polygons. 2. Backend Development Set up PostgreSQL + PostGIS database. API endpoint: input GPS (lat/lon) → return parcel polygon + survey number. Spatial queries: ST_Contains, ST_Distance for nearest parcel lookup. Host via Node.js/Python backend (REST/GraphQL). 3. Frontend (Basic App / Demo) Web or Mobile (React / React Native / Flutter). Map integration (Google Maps SDK OR MapLibre/Mapbox). Show GPS blue dot, highlight parcel boundary, display survey number. Required Skills Strong GIS experience: QGIS, GDAL/OGR, map georeferencing. Knowledge of PostGIS and spatial queries. Experience with GeoServer / TileServer GL / vector tiles. Backend development: Node.js / Python (FastAPI / Express). Frontend: React / React Native / Flutter with Google Maps / MapLibre integration. Ability to integrate AI/ML features in later phases (e.g., AI-powered land parcel recognition, OCR on land records, predictive insights).
