AI-powered geospatial intelligence platform that analyzes real-time data to detect investment hotspots using satellite imagery, building permits, foot traffic patterns, and utility usage signals.
This website now uses actual real-time data from multiple public APIs and open data portals:
- Primary Source: OpenStreetMap Overpass API for construction detection
- Data Provided:
- Active construction sites
- New building detection
- Land use changes
- NDVI (vegetation) change analysis
- Coverage: Real-time queries for all 4 cities
