National 3DEP Program• The primary goal is to systematically
collect enhanced elevation data in the form of high-quality Lidar data over the entire US (IFSAR for Alaska).
• The 3DEP initiative is based on the results of the National Enhanced Elevation Assessment, which indicated an optimal benefit to cost ratio for Quality Level 2 (QL2) data collected over 8-years to complete national coverage.
• The implementation model for 3DEP is based on multi-agency partnership funding for acquisition

Other ReportsGovernor’s Commission on Climate Change (2008)Recommendation 14N. The General Assembly should provide funding
for the Virginia Geographic Information Network to acquire and process LiDAR data for the entire state. LiDAR data should be first acquired for the coastal zone, which will cost approximately $6 million, and then for the rest of the state.
VIMS Recurrent Flooding Study Finding 3. Data is often lacking for comprehensive and/or fine
resolution analysis of flood risks in the region.Recommendation 2. The State should initiate identification, collection
and analysis of data needed to support effective planning for response to recurrent flooding issues in Virginia.
