- The dataset includes buildings over 400 sq ft and 12 ft tall, excluding temporary structures; nearly a quarter of existing buildings were constructed in the 1920s.
- Building measurements are primarily derived from photogrammetry (93%), with 95% accuracy within ±2 feet, and aerial photography has been used for over 100 years.
- A historic dataset captures demolished or altered buildings, allowing analysis of building lifespans, including some over 200 years old.
- Visualizations combine building footprints with elevation data from LiDAR scans, showcasing physical city elements like hills, trees, and infrastructure.
