Midyear meeting
February 28, 2012
To define, maintain & provide access to the National Spatial Reference System (NSRS) to meet our Nation’s economic, social & environmental needs.
National Geodetic Survey Mission
• Latitude• Longitude• Height• Scale• Gravity• Orientation• Time Variations Horizontal / Vertical Control
(NSRS)
The NSRS continues to evolve
Passive Control
(Monuments)
Active Control(CORS)
Positioning America in a dynamically changing world.
Continuously Operating Reference Stations (CORS)
1800+ Stations on Four Continents$1 Billion in Direct Benefits FY2011
Online Positioning User Service (OPUS)
1.5 Million Solutions since 1992
$207 Million in Estimated Benefits FY2011
