The URL for the Tribal Directory Assessment Tool (TDAT) has been changed. Please update your bookmarks and documents to https://egis.hud.gov/tdat. Click here to go to TDAT now.

The new TDAT 3.0 has all the same functions as earlier versions, but the look is different, to match other HUD eGIS applications. It also now functions on mobile devices.

Please continue to send corrections and updates for TDAT to EnvReview@hud.gov.
