Roof measurements.
Delivered in seconds.
Squares, pitch, facets, ridge, hip, valley, eave, rake. Derived from public aerial imagery and 3D photogrammetry — with cross-checks against Google Solar API data.
Three public data sources. One measurement truth.
Fetch high-resolution imagery
Google Solar API aerial RGB + 0.1 m DSM GeoTIFF for the parcel. Fallback to USGS 3DEP when unavailable.
Segment roof planes
Sobel gradients on the DSM produce surface normals; region-growing from Solar API seeds yields per-facet planes. Least-squares fit locks pitch, azimuth, and slant area.
Cross-check and report
Three independent area estimates — DSM, Solar whole-roof, footprint scaled — must agree. Final report ships with confidence score and full edge breakdown.
Calibrated against EagleView ground truth.
Every release runs through a regression harness on three sealed EagleView reports. Pass threshold: squares within 5%, facet count within ±2, predominant pitch match.
