U.S. National Grid conversion software added to the Geodetic Toolkit (Feb 2002)
- The national grid will improve public safety, commerce, and aid the casual
GPS user with an easy to use geoaddress system for identifying and determining
location with the help of a USNG gridded map and/or a USNG enabled GPS system.
[PDF format] published by the US National Grid Standards Working Group.
- NGS at the 2002 Olympics (April 2002)
In recognition of the 2002 Winter Olympic Games in Salt Lake City, the National

position aircraft during airborne mapping operations.
SWaPS -- Monitoring Underwater Environments with GPS
(Sept 20, 2001)
Members of NOAA's National Geodetic Survey (NGS) rigged a Global Positioning System (GPS) receiver to a digital camcorder connected to a flotation device.

Geodetic Programs Needs of Louisiana and Wisconsin
NGS sets a geodetic marker at the
USA's Population Center (May 9, 2001)
NGS is encouraging a marker be set at each State Population Center.
OnLine Positioning User Service
(OPUS) (February 26, 2001)
OPUS is added to the Geodetic
Tool Kit. OPUS allows users to submit their GPS data files in RINEX
format to NGS, where the data will be processed to determine a position
using NGS computers and software. Each RINEX file that is submitted will
be processed with respect to the 3 nearest National CORS sites.
