- [USA Structures](https://disasters.geoplatform.gov/USA_Structures/): Building footprints, heights and occupancy from FEMA's USA Structures.
- [SkyPSI estimator](https://skypsi.com/estimates/methodology/sources-and-licensing/): SkyPSI's own price model, calibrated rates and building-class rules.
- [USGS 3D Elevation Program](https://www.usgs.gov/3d-elevation-program): Lidar elevation data that gives building heights where other sources have none.
