The U.S. Geological Survey: A Rich Scientific Tradition in the Department

• f Interior

+ The U.S. Geological Survey: Organizational Chart

+ The U.S. Geological Survey: Regions

+ The National Geospatial Program

• Provides leadership for USGS

geospatial coordination, production, and service activities

• This includes The National Map:

–Base Data –Map Products –Geospatial Web Services

• Center of Excellence for

Geospatial Information Science (CEGIS)

+ NGTOC Mission

As the primary operational organization of the National Geospatial Program:

The NGTOC provides essential support for the acquisition and management of trusted geospatial data, products, and services through world-class geospatial technical expertise and customer service for the U.S. Geological Survey and the Nation.

+ NGTOC Major Functions

• Acquire geospatial data (partners and contracts)
• Perform quality assurance and data integration
• Manage and maintain national level databases for:
• Geographic Names,
• Hydrography,
• Elevation data,
• Boundaries, Man-made structures, Transportation data
• Perform technical support and training
• Provide stewardship services
• Develop and maintain standards
• Develop and deliver products and services
• Perform applied geospatial research and systems development
• Provide staff and support Center of Excellence for Geospatial Information

Science (CEGIS) research

+ FY 2015 NGTOC Profile

• Two locations (Denver Federal Center, USGS Rolla Building)
• Number of Government Employees by appointment type:

– 162 (full-time and part-time permanent) – 15 Career Interns/Recent Graduates/Term

• 39 - On-site Technical Support Contractor
• 20 - Student Contractors
• FY15 Annual Budget Information:

– $28,454,216 (all sources, NGTOC operational expenses) – $33,975,406 (all sources, off-site contracts)

+ NGTOC/CSS Employees by Occupational Series

+ Skill Mix Change Trends

• Decreasing need for these skills:

– Routine production tasks that do not require subject matter expertise – Skills needed for large volume, repetitive tasks – Secretarial and traditional administrative staff

• Increasing need for these skills:

– Higher level SMEs in photogrammetry; geodesy; statistics; computer science; digital cartography/GIS with programming and subject matter and software knowledge and experience; lidar expertise; data management; higher level IT architecture design and implementation skills; project management, including development project management in an Agile environment

• f Work 2015: Key

Projects

+

• Key data layers continually updated:

– High resolution digital elevation data (including 3DEP) – High-resolution digital orthorectified imagery – Vector data including hydrography, transportation, structures, boundaries – Geographic Names (GNIS) – Landcover data

• Public Domain Data to support:

– USGS topographic maps at 1:24,000 scale – Products and services at multiple scales and resolutions – Analysis, modeling and other applications at multiple scales and resolutions

• Derived Products:

The National Map (TNM)

+ Creating the Next Generation USGS Topographic Maps

US Topo - The Next Generation of USGS Topographic Map

• Built from The National Map data layers
• Digital, GeoPDF Format
• Available free for download
• Aerial Image base
• Core feature layers
• Regular update (every 3 Years for

CONUS)

• Averaging well over 100K downloads per

month

+ Creating the Next Generation USGS Topographic Maps

+ Creating the Next Generation USGS Topographic Maps

Alaska Mapping Effort

• Acquiring state-wide IfSAR data for elevation products
• New SPOT satellite imagery at 2.5 meter resolution
• Feature updates including hydrography, contours,

transportation, federal boundaries, names & woodlands

• First 1000+ US Topos are now available! (1:25k)

+ Historic Topographic Map Collection (HTMC)

• 200,000 scanned historical maps

available

• All scales
• Multiple publication dates per cell
• Available for free download
• Geopdf and Geotiff formats
• Custom Viewer for review and

downloading

+ Improving the Nation’s Elevation Data

• The NGTOC provides operational support for the

acquisition, quality control, product generation and distribution of 3D Elevation Program (3DEP) products

• In 2015 new elevation products became available

through The National Map, including: – lidar point cloud – Ifsar generated digital surface model and

• rthorectified radar intensity image

– 1-meter standard DEM

+

Lidar Point Cloud Digital Surface Model Orthorectified Radar Image

+ Standard DEMs

Nationally seamless DEMs continue to be updated with new 3DEP data

+ The National Map - Hydrography

+ The National Map - Hydrography

NHD

• Advanced relational/feature-

based data model

• Continuous updates through a

network of other Federal and State Data Stewards

• Analytical capabilities inherent in

flow network/linear referencing

• Integrated with Watershed

Boundary Dataset

+ National Hydrography Dataset (NHD)

• Surface water component of The National Map
• General mapping and analysis of surface-water systems
• Seamless digital vector dataset for GIS use
• Features: lakes, ponds, streams, rivers, canals, dams and

streamgages.

• Flow network - tracing water downstream or upstream.
• Addressing system: Reach codes and linear referencing

– link - water discharge rates, water quality, fish population, etc.

• Scale: Medium (1:100,000-Scale) High (1:24,000-Scale)
• Maintenance: Partnership - Stewardship Model

– EPA, FS, State & Local partners
