Property intelligence and change detection
Compare any two image dates. Find new roofs, extensions, driveways, patios and removed vegetation, with areas in square metres.
See properties differentlyUnderstand every change
Historical aerial imagery and GeoAI that show what changed on a property, when, and by how much. We also manage properties with the same technology.
Detected change: driveway (+21 m²) and patio (+32 m²)Potential increase: 53 m²
DATA CAPTURE
Aerial imagery today and, from 2027, ground-level data from a mobile mapping vehicle and drone.
AI ANALYSIS
GeoAI extracts buildings, roofs, surfaces and changes automatically across whole portfolios.
MEASUREMENT
Areas and changes are measured and delivered as reports, GIS layers and exports.
Driveway+21 m²
Patio+32 m²
Total hard surface+53 m²
Property intelligence from the record of what was there
Compare historical and current aerial imagery to identify additions such as driveway extensions and patios. In municipalities where stormwater charges reflect measured impervious area, these changes can affect a property’s assessment.
- Driveway Expansion
- Patio Construction
- Impervious Surface Increase
- Detailed Area Measurements
