FGCS 1999 Work Plan

FEDERAL GEOGRAPHIC DATA COMMITTEE
GEODETIC CONTROL SUBCOMMITTEE
1999 WORK PLAN

Geodetic Control Subcommittee

The Federal Geodetic Control Subcommittee (FGCS) of the Federal Geographic Data Committee exercises government-wide leadership in coordinating the planning and execution of geodetic surveys, in developing standards and specifications for these surveys, and in the exchange of geodetic survey data and technical information. FGCS coordinates Federal agencies' aspects of surveying that are governmental responsibilities. These responsibilities include standards setting, testing new geodetic instrumentation and operational systems, coordination of user agency requirements, and dissemination of government data to user agencies.

The FGCS acts to ensure that the Global Positioning System (GPS) will continue to meet the positioning needs of the Federal civilian community and works to strengthen the ties between the GPS positioning and navigation communities. This responsibility will be implemented through its role as GPS Interagency Advisory Council (GIAC) to the Department of Transportation PosNav Executive Committee.

Objective: Evaluate surveying systems, including the instrumentation, hardware, software, and procedures that comprise that system.
Action: Complete testing of the Zeiss digital bar code level DINI10.
Expected outcomes: To make the data available to the public. The data will also get some analysis work done by FGCS personnel and a report published and made available on the web.
Date: Spring, 1999
Responsible Party: FGCS/Instrument Working group, DOT, USGS, and NOAA
Action: Test of Topcon digital bar code level.
Expected outcomes: To make the data available to the public. The data will also get some analysis work done by FGCS personnel and a report published and made available on the web.
Date: 1999
Responsible Party: FGCS/Instrument Working group, DOT, USGS, and NOAA
Action: Test of two GPS receivers.
Expected outcomes: FGCS personnel will participate in the test and observe the systems as data is gathered. During the test week, the data will be processed and FGCS observers will participate and make comments on how the system adheres or does not adhere to accepted standards. This type of interaction during the tests has led to some good improvements that the manufacturers have made to their products.
Date: 1999
Responsible Party: FGCS/Instrument Working group, DOT, USGS, and NOAA
Action: Complete updating of FGCS standard operational procedures, forms, etc.
Expected outcomes: Improvements will continue to be made to the testing process. After each test, the manufacturers are asked how the test can be improved. Improvements have been from the updating of forms, to test descriptions, posting information to the web, etc. Focus will be on completing the common documents between testing and posting this and other pertinent data to the web site.
Date: 1999
Responsible Party: FGCS/Instrument Working group, DOT, USGS, and NOAA
Action: Outreach and education.
Expected outcomes: Continued outreach to involve more parties within the federal government, as well as state and local governments. Last year the charter was amended to allow this. Intention is to write articles, present talks and continue general outreach through various web sites, as well as conference activities.
Date: 1999
Responsible Party: FGCS/Instrument Working group, DOT, USGS, and NOAA

Objective: Outreach and Education - "Interpolation Test / Documentation / Guidance to Users"
Action: Develop 'front page' web resources to educate potential Differential Global Positioning Systems (DGPS) users to Continuously Operation Reference Station (CORS) and Nationwide DGPS (NDGPS) data solutions. 'INTERPO' software methods and accuracies should highlight the usability of CORS data versus setting up new stations.
