A building file carries the source of each field, and SkyPSI shows that source beside the fact. - [County and state public records](https://comptroller.texas.gov/taxes/property-tax/): Situs addresses, parcel numbers, land use, year built and floor counts from county appraisal districts and state open data. - [USA Structures](https://disasters.geoplatform.gov/USA_Structures/): Building footprints, heights and occupancy from FEMA's USA Structures. - [Overture Maps addresses](https://docs.overturemaps.org/attribution/): Street addresses from the Overture Maps addresses theme. - [Overture Maps places](https://docs.overturemaps.org/attribution/): Business and place names from the Overture Maps places theme. - [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.
