NEEA 2012 SummaryThe National Map

+National Digital Elevation Program (NDEP)Status of Elevation Data

1996 - 2011 28% coverage - 49 states 15% coverage – Alaska 30+ year replacement cycle Program is efficient – less

than 10% overlap of coverage Cooperative data projects

work Data quality variable

Why is this a problem? Remaining 72% coverage is

30 or more years old. Alaska – very poor quality Meets 10% of need. Current

and emerging needs require much higher quality data.

+Recommended Elevation Data Program

Advantages: Achieves the majority of benefits High benefit-cost ratio and net benefits Benefits realized in 8 years instead of 30+ years for status quo Meets all lower QL requirements and partially satisfies QL1 Cost efficiencies achieved through large area acquisition

strategy

QL2 LiDAR* - 8 year acquisition (3)

10

* Note: All scenarios include QL5 (IfSAR) for Alaska

+Why QL2?

Upgrade path (buy up options) to QL1 more affordable to partners

QL 3 data cannot be upgraded later, would need to be re-flown to meet needs for higher quality data

Ecosystem services benefits were not quantified but usually require QL2 and better

Emerging high value needs (ex. Land navigation) depend on QL2

Addresses growing trend toward higher resolution (GPSC)

11

Additional Considerations

12+Summary of Findings and Conclusions

Status quo program relatively efficient but meets less than 10% of measured needs.

All program scenarios provide favorable benefit cost ratios.

All program scenarios combine multiple requirements and collect data in large regular blocks to achieve improved cost efficiency.

IT infrastructure needed to manage data for all scenarios.

No technical barriers to moving ahead

Major dollar benefits are realized from high quality data.

+Introducing 3DEP

3DEP is the name developed for the recommended program

Purpose is to communicate that the program is more than bare earth elevation – the point cloud and other basic derivatives will be distributed and archived

Tagline under development: 3DEP gives you the perspective to see more than just what’s on the surface

+A Proposed 3DEP Funding Strategy

Coalition of Federal agencies to commit funding annually to a national program.

Top ten Federal agencies in rank order of benefits: NRCS, USACE, DISDI, USGS, NOAA, FEMA, EPA, USFS, FAA, and NGA

States and other partner agencies will be invited to participate to provide balance of program cost

Collection priorities will be based on coalition partner agency needs

Partners may buy up to higher quality level (Quality Level 1)

Acquisition cycle scales with funding

Cooperatively Funded Program Executed by USGS

15

+3DEP Development – Next Steps Communications ongoing with potential

partners and other stakeholders

Developing 3DEP branding materials

NGAC endorsement of program recommendation and strategic advice on funding strategy

Develop governance model for community review (June/July) Flexible process to meet annual requirements of

partner agencies Use existing mechanism as the forum for

negotiations: National Digital Elevation Program Use lessons learned and model after successful

partnerships, e.g., National Agriculture Imagery Program

16

+Outreach Efforts

Associate Director, Federal Agency Outreach USACE, DISDI, FEMA, FAA completed, five more planned Positive tone, agencies understand need for better elevation Agencies welcome opportunity to stretch limited dollars Agencies interested in model initiative language Annual planning cycle and project specific needs present a

coordination challenge

Active follow-up needed to advance funding opportunities

Broader outreach strategy to States, select industries and associations under development.

17

+NGAC, NSGIC Endorsements

NGAC Recommendation: The NGAC endorses a national elevation program (i.e., 3D Elevation Program, or 3DEP) as described in the National Enhanced Elevation Assessment conducted by the U.S. Geological Survey (USGS). The NGAC encourages the USGS, the Department of the Interior, and Federal partner agencies to refine, adopt, and implement this program in partnership with other levels of government, academia, and the private sector.

NSGIC: Letter of endorsement was sent to the USGS Director in April. Member states are supporting the recommended program and are asking that there be advanced planning and buy up opportunities.
