NGP User Engagement Office

Hazards & Geologic Mapping Community of Use

The Hazards & Geologic Mapping COU is focused primarily on science applications for National Geospatial Program (NGP) products and services that support geologic hazards research and mitigation activities.

Scientists and managers from the U.S. Geological Survey (USGS) and the broader geologic hazards community are engaged in:

  • Soliciting requirements for NGP products and services through interactive dialog, site visits, conference attendance, and training opportunities
  • Promoting the applicability of NGP products and services to address critical geologic hazards science needs
  • Identifying opportunities to enhance, improve, and expand the product and service offerings from NGP in support of geologic hazards science

Users include USGS scientists and managers concerned with research and mitigation activities in the following focus areas:


  • Defining the location and relative activity of active fault zones using high-resolution elevation data derived from lidar
  • Defining the location and relative activity of landslide processes using high-resolution elevation data derived from lidar
  • Volcano hazards maps and flow models using topography as model input
  • Measurement of sea-level rise and land subsidence in the coastal zone, using lidar
  • Preparing maps of scientific findings, such as hazard delineation, using The National Map as a base (US Topo, scanned topographic maps, shaded relief maps from the National Elevation Dataset are examples)

Initial Community of Use Areas of Interest

  • Establishing a technical committee to formulate, review and prioritize requirements for National Geospatial Program (NGP) products and services that support geologic hazards activities
  • Committee membership by USGS scientists and managers from geologic hazards focus areas
  • Education and outreach regarding the applicability of NGP products, services and capabilities followed by solicitation of user needs and determinination of intersections between NGP offerings and user needs. Additionally, identification of opportunities for improvement and enhancement of NGP products and services.
  • NGP visits to the Geologic Hazards Science Center in Golden, Colorado, and Volcano Hazards Program locations to establish ongoing communication and coordination.
  • Identification of and participation in training opportunities for Community of Use Coordinator and USGS Geospatial Liaisons to promote better understanding and awareness of overall geologic hazards needs

Technical Committee

The Hazards & Geologic Mapping COU Technical Committee was formally established on February 15, 2013. The Technical committee assists the COU coordinator in understanding and prioritizing enhancement requests submitted by users. Initially USGS mission areas are heavily represented within the COU technical committee, however as the process matures more external users will be included representing other Federal agencies, state and local users, academia, and private sector users as appropriate.

Future Plans

  • Working through the Technical Committee and the USGS Geospatial Liaisons, identify user engagement points of contact outside of the USGS
  • Identify conferences, meetings, and other activities where liaisons and the Community of Use Coordinator can engage a broad user base with an interest in geologic hazards, for the purpose of soliciting user needs, developing networks, and promoting the applicability of NGP products and services to geologic hazards activities
