Project description:
"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)." (client-provided description)
