The National Map’s Structures Tint dataset represents manmade structures using broad-area tints rather than defining the exact shape of individual buildings.
The data was provided by Oak Ridge National Labs and the Federal Emergency Management Agency.
This dataset was introduced in 2021 and is designed for use at the 1:24,000 scale (the standard scale for USGS topographic maps) or smaller. While improvements to spatial accuracy are ongoing, use at larger scales is not advised.
You can currently access the Structures Tint Dataset through the TNM Basemap. In the future, you will be able to access the data through The National Map Download Client, The National Map Services, and The National Map Viewer.
