Height Modernization Western States Regional Webinar

 

Height Modernization Western States Regional Webinar

Tuesday, November 19, 2013

10:00am PT - 2:00pm PT (1:00 – 5:00 pm ET)

 

This webinar covered the following topics:
  • basic information about the National Geodetic Survey’s National Height Modernization Program, and supporting services such as OPUS
  • future plans for a new national vertical datum,
  • the type of data we need today and how you can collect it,
  • how federal and state organizations are implementing Height Modernization, and
  • elevation related challenges you might face if you work in the western United States.
Background:
  • Height Modernization is an initiative focused on establishing accurate, reliable heights using Global Navigation Satellite System (GNSS) technology in conjunction with traditional leveling, gravity, and modern remote sensing information.  
  • Elevation (orthometric height) information contributes to informed decision making and impacts a wide range of important activities including mapping and charting, flood risk determination, transportation infrastructure, land use and ecosystem management.
