Construction Site Detection - Satellite + Vision LLMs

2025•Case Study

Satellite-driven construction detection with POI mapping for faster rural verification.

The Challenge

  • Manual satellite analysis is too slow for scale
  • Need detection at Gram Panchayat to district levels

The Solution

  • Integrated Bhoonidhi API for imagery retrieval

  • GeoTIFF tiling pipeline for processing

  • Vision LLM analysis and POI mapping for nearby infrastructure

Impact

  • Faster detection of new construction activity

  • Coordinates and visibility into supporting infra like material shops
