- County and state public records: Situs addresses, parcel numbers, land use, year built and floor counts from county appraisal districts and state open data.
- USA Structures: Building footprints, heights and occupancy from FEMA's USA Structures.
- SkyPSI estimator: SkyPSI's own price model, calibrated rates and building-class rules.
- USGS 3D Elevation Program: Lidar elevation data that gives building heights where other sources have none.
