1 3D Elevation Program (3DEP) Sheri Schneider, USGSGeospatial LiaisonFebruary 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 AlaskaCourtesy of NRCS2 points per sq. meter. Complete one cycle of data collection in 8 yearsClassified point cloud data and 1 meter DEMsPartnership model funded primarily by Federal agencies and states.Operational in January 2015 with full data coverage by 2022

5 Draft CriteriaHighest net benefits identified in the NEEA requirements studyFigure 6, 3DEP Plan 1.0
6 Draft CriteriaHighest net benefits identified in the NEEA requirements studyFederal, state or regional partner elevation data acquisition planNo existing lidarExisting lidar does not meet 3DEP requirementsExisting lidar older than 8 years oldSignificant topographic changeSerious 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 proposalsPartners will propose an acquisition approach that best meets their needs, either:USGS Geospatial Products and Services Contract (GPSC)Seven prime contractors with multiple subcontractorsWill re-compete in 2014State’s own authorities and contracts to acquire data that meet the 3DEP specification.
8 Draft Deliverables/Specifications Raw Point CloudClassified Point CloudHydro-flattened Bare Earth DEMs, 1 meter grid cellBreaklines – when used for hydro-flatteningMetadataRMSEz from ≤ 9.25 centimeters2 pts/sq. meter, optional buy up to 8 pts/sq. meterNominal pulse spacing (NPS) 0.7 meters
9 Draft State Roles and Responsibilities Coordinate and facilitate local and regional partnershipsAdvocate and support the goal of achieving nationwide coverage. Participate in partnership data acquisition projectsAdopt national specifications and standardsMake resulting data available to the national programMay collect data to a higher quality specificationDevelop 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. mtrTable F-1, NEEA ReportEstimated Cost based on acquisition by 1 Degree Cells, NEEA Report1 Degree Cell size ranges from 3000 – 4000 sq. mi.Estimated Cost/ 1 degree cell - $1 million – $1.3 million
