1 3D Elevation Program (3DEP)
Sheri Schneider, USGS Geospatial Liaison February 18, 2014

2 3D Elevation Program (3DEP)
A national USGS initiative to improve the elevation data and to support other mission critical needs for lidar data in the conterminous US, Hawaii and territories and for ifsar data in Alaska Courtesy of NRCS 2 points per sq. meter. Complete one cycle of data collection in 8 years Classified point cloud data and 1 meter DEMs Partnership model funded primarily by Federal agencies and states. Operational in January 2015 with full data coverage by 2022

3 Comment Period Extended
Products Criteria Data Acquisition Contracts Specifications State Roles and Responsibilities DRAFT Comment Period Extended to Friday 2/12/2014

4 Draft 3DEP Standard Products
Product Name Source(s) Planned Product Lidar Full Point Cloud - Unclassified Lidar – QL1, QL2, QL3 Project areas by special request Lidar Full Point Cloud - Classified Lidar - QL1, QL2, QL3 Project tiles by download Ifsar Digital Surface Model Ifsar – QL5 Orthorectified Ifsar Intensity Image Source resolution DEM Lidar, Ifsar 1 meter DEM Tiles (TBD) by download 5 meter DEM Ifsar 1/9 arc-second DEM - legacy Lidar, Ifsar, Photogrammety 15 min block by download 1/3 arc-second DEM 1x1 degree block by download 1 arc-second DEM 2 arc-second DEM Lidar and Ifsar, Photogrammetry Elevation Point Query 1/3 arc-second, 1 arc-second in AK Application service Hillshade Viewing service 5 to 120 foot Contours 1 degree block by download and viewing service Standard Oregon Products not included - highest hits, intensity image, ground only points. Bare Earth DEM is hydroflattened.

5 Draft Criteria Highest net benefits identified in the NEEA requirements study Figure 6, 3DEP Plan 1.0

6 Draft Criteria Highest net benefits identified in the NEEA requirements study Federal, state or regional partner elevation data acquisition plan No existing lidar Existing lidar does not meet 3DEP requirements Existing lidar older than 8 years old Significant topographic change Serious and significant hazards (earthquakes, landslides, etc.) 1500 – 5000 sq. mi in size, increasing emphasis on larger projects

7 Draft Data Acquisition Contracts
USGS will manage the process to accept partnership proposals Partners will propose an acquisition approach that best meets their needs, either: USGS Geospatial Products and Services Contract (GPSC) Seven prime contractors with multiple subcontractors Will re-compete in 2014 State’s own authorities and contracts to acquire data that meet the 3DEP specification.

8 Draft Deliverables/Specifications
Raw Point Cloud Classified Point Cloud Hydro-flattened Bare Earth DEMs, 1 meter grid cell Breaklines – when used for hydro-flattening Metadata RMSEz from ≤ 9.25 centimeters 2 pts/sq. meter, optional buy up to 8 pts/sq. meter Nominal pulse spacing (NPS) 0.7 meters

9 Draft State Roles and Responsibilities
Coordinate and facilitate local and regional partnerships Advocate and support the goal of achieving nationwide coverage.  Participate in partnership data acquisition projects Adopt national specifications and standards Make resulting data available to the national program May collect data to a higher quality specification Develop a statewide program strategy and seek funding to participate in partnership activities

10 Estimated Cost Rough estimate - $32 million for Oregon statewide
$20 million to buy up to 8 pts/sq. mtr Table F-1, NEEA Report Estimated Cost based on acquisition by 1 Degree Cells, NEEA Report 1 Degree Cell size ranges from 3000 – 4000 sq. mi. Estimated Cost/ 1 degree cell - $1 million – $1.3 million
