Field notes
The homepage names its source material, including USGS 3D Elevation Program lidar, OpenStreetMap, and credited tree-height data from Meta and World Resources Institute. Its schedule lists Colorado as a 36-area region, followed by Utah, the Northern Rockies, the Pacific Northwest, California and the Southwest, the Northeast, and the Midwest and Southeast. The comparison dimensions are stated, but the scoring formula is not shown in the extracted page.
