Geospatial Data Lifecycle

Office of Management and Budget, Circular A-16 Guidance

For more than 15 years, the

USGS has managed the

National Elevation Dataset

(NED) and coordinated

acquisition through the

National Digital Elevation

Program (NDEP) on a

project-by-project basis

Landslide Mapping and Analysis

+ National Enhanced Elevation Assessment

Sponsored by the National Digital Elevation Program (NDEP) and

funded by USGS, NGA,FEMA, NRCS and NOAA to:

Document national requirements for improved elevation data from technologies

such as LiDAR and IfSAR

Estimate the benefits and costs of meeting these requirements

Evaluate multiple national enhanced program scenarios for government

consideration

602 mission-critical activities that require enhanced elevation data

were identified by:

34 Federal agencies and 50 states

A sampling of local governments, tribes, private and not‐for profit organizations

A national program has the potential to generate $1.2 billion to

$13 billion in new benefits each year

+ What is the 3D Elevation Program?

Accelerate data acquisition and collaboration among Federal, state, local and

tribal partners to systematically complete national 3D elevation data

coverage in eight years (lidar in conterminous U.S., Hawaii, and the

Territories; and ifsar data in Alaska)

Refresh the National Elevation Dataset (NED) with new lidar and ifsar elevation

data products and services

Meet the 3D elevation needs of USGS science, DOI, States and the broader

community

Achieve 25 percent cost reductions through larger acquisition projects

Increase the overall national investment in 3D elevation to $146 million

annually to return more than $690 million annually in new benefits

+ Broad Agency Announcement On July 18, 2014, the USGS issued a Broad Agency

Announcement that provides detailed information on how to partner with the USGS and other Federal agencies to acquire high-quality 3D data.

Information and contacts are now available at FedBizOps website. www.fbo.gov

Offerors may contribute funds toward a USGS lidar data acquisition activity via the Geospatial Products and Services Contracts or they may request 3DEP funds toward a lidar data acquisition activity where the requesting partner is the acquiring authority.

Federal agencies, state and local governments, tribes, academic institutions and the private sector are eligible to submit pre-proposals.

Status and Plans

Current BAA in progress – timing has been challenging

First year is an opportunity to “learn by doing” and to gain new insights into what is needed to make it more robust

Future year development Coordination – current thinking is

to hold open 3DEP coordination meetings 1-2 times each year in each state or region

Annual and multi-year plans – make Federal, state and other plans and areas of interest available online, as the “planned” companion to the “available” status of the inventory. North Carolina and Alaska – Two examples that are working now.

+ U.S. Interagency Elevation Inventory

The USGS Geospatial Liaisons are the State Conduit to

updating the elevation inventory.

Major Update - January to April - “Update Drive” to incorporate

the fiscal year’s acquisitions and support the 3DEP Data

Acquisition Process

Minor Update - August to September - “Update Drive” to update

any changes prior to Annual Inventory Analysis Activities

Inventory results available – November
