About National Geospatial Partnerships
The National Map partnership network cultivates and maintains long-term relationships with partners and develops agreements for The National Map and other initiatives that support USGS science. Partnerships are the foundation of The National Map because they leverage funding across organizations to provide significant cost savings, reduce redundancy in geospatial data acquisition and stewardship, and ensure availability of common base data to a broad range of users and applications.

Liaison Activities

Fiscal Year 2012 Highlights

Agreements

      Elevation

  • USGS Coastal Marine Geology Program, USGS Eastern Geographic Science Center, USGS National Wetlands Research Center, U.S. Army Corps of Engineers - Partnership to acquire over 1,640 square miles of lidar over Atchafalaya Basin to support multiple studies including flood analysis and response, vegetation mapping, structures mapping, land use planning, and habitat modeling by providing data for analysis.

      Hydrography

  • Louisiana Department of Transportation and Development - Partnership to assess discrepancies between the National Hydrography Dataset (NHD), Geographic Names Information System (GNIS), and local sources for geographic names.

      Imagery

  • National Geospatial-Intelligence Agency - Partnership to acquire over 630 square miles of high-resolution imagery over Shreveport to support community planning, emergency response, and science, environmental, and mapping user communities.
  • National Geospatial-Intelligence Agency - Partnership to acquire over 602 square miles of high-resolution imagery over New Orleans to support community planning, emergency response, and science, environmental, and mapping user communities.
  • U.S. Army Corps of Engineers - Partnership to acquire over 20,158 square miles of high-resolution imagery over portions of the Louisiana Coast to support community planning, emergency response, and science, environmental, and mapping user communities.
  • Coastwide Reference Monitoring System - Partnership to acquire approximately 20,000 square miles of aerial imagery in coastal Louisiana to help determine the rate and structure of wetland change and recovery throughout Louisiana’s coastal zone and to ensure that Louisiana’s strategic coastal plan is effective in re-creating a sustainable coastal ecosystem.

FGDC CAP Grant Support

  • Louisiana State University and A&M College - (Category 3: Expanding the State GIS Inventory) - This project will collaborate with Louisiana GIS Council members to collect, maintain, and distribute Louisiana geospatial datasets through the GIS Inventory System. The Louisiana Geographic Information Center (LAGIC) currently acts as a node on the National Spatial Data Infrastructure for the distribution of Louisiana geospatial data and associated metadata records.

Other Activities

  • Science Support - Assisted USGS biology, geology, and water scientists in obtaining imagery, elevation, and other geospatial data.
  • 3D Elevation Program Inventory - Validated information on known datasets and documented new datasets to update the national inventory of high-resolution elevation data - http://www.csc.noaa.gov/inventory/.
  • Outreach - Conducted and coordinated National Geospatial Program outreach activities by attending a range of meetings, participating in conferences, and coordinating trainings and workshops to support the geospatial community in the State.
  • Emergency Response - Liaisons provide general geospatial data discovery and acquisition assistance during emergencies as those events occur throughout the fiscal year.
