Update Policy
As we approve data from the contractor they are posted here. Areas within many of the bare-earth DEMs can be improved by further processing of the all-return point data to better isolate bare-earth points. As we make these improvements we will upgrade the bare-earth DEMs and derivative images posted here.

Technical Assistance
