3D Elevation Program 3D data include surface elevations and
natural and constructed features 3DEP increases the quality level
of lidar being acquired to enable more accurate understanding,
modeling, and prediction Goal to acquire national coverage in 8
years 3 3DEP Applies ground- breaking lidar technology to acquire
and distribute 3D data Addresses a broad range of critical
applications of national significance

Forest Habitat and Biomass with Lidar Metrics estimated from
lidar for forestry inventory and habitat assessments include:
Canopy closure, width and height Tree stem density Total tree
volume (m3/ha) Biomass 12 Habitat suitability is closely related to
forest structure

What is the 3D Elevation Program? Apply groundbreaking
technology to address the mission-critical requirements of 34
Federal agencies, 50 states, and a sampling of local governments,
tribes, private and not for profit organizations documented in the
National Enhanced Elevation Assessment Increase the overall
investment in 3D data from about $50 M to $146 M annually to return
more than $690 million annually in new benefits Leverage
collaboration among Federal, states, local and tribal partners to
systematically complete national 3D data coverage in eight years
Leverage the capability of private industry mapping firms, create
jobs Achieve cost efficiencies 16 3DEP is a call for community

U.S. Interagency Elevation Inventory 17 2013 Status Map of
Publicly Available Lidar and Ifsar Only 4% of the lower 49 states
meets the 3DEP quality goal (QL2 or better) lidar coverage More
than half the State of Alaska needs ifsar data to complete the 3DEP
goal for coverage To view the inventory see:
