<P>3.  Uses of Data: What are the end uses of this data?  How does it benefit customers, support lead
and other agency missions, etc.?</P>

<P><FONT FACE="Times New Roman">- Geodetic control provides a common reference system for establishing coordinates for all
geographic data.  All NSDI framework data and users' applications data require geodetic control
to accurately register spatial data.  The National Spatial Reference System is the fundamental
geodetic control for the United States.</FONT></P>

<BR WP="BR1"><BR WP="BR2">
<P><FONT FACE="Times New Roman"></FONT>- Geodetic control provides spatial consistency, accuracy, timeliness, and ease of access to spatial
reference in support of public safety, economic prosperity, and environmental well being.  </P>

<BR WP="BR1"><BR WP="BR2">
<BR WP="BR1"><BR WP="BR2">
<P>4.  Charter/Plan:  Do you have a current charter or plan for collection?  Should it be updated?</P>

<P>- Yes, there is a charter, from 1995. </P>

<P>- Yes, there are updates needed.  One work group (<FONT FACE="Times New Roman">Geodetic Control and Surveying
Requirements Work Group</FONT>) in the initial charter has been disbanded and needs to be dropped
from the charter.  Another (Spectrum Issues Work Group) has been instigated and needs to be
added to the charter.</P>

<P>8. 	Leadership:  Describe your active leadership role with others (private, local, State, Federal)
who collect and use this data.</P>

<P>	- NGS chairs the FGCS as well as three of the work groups (Instrumentation, Methodology,
and Vertical Reference).</P>

<P>	</P>

<P>	- FGCS ensure that the Global Positioning System (GPS) will continue to meet the
positioning and timing needs of the Federal civilian community and work to strengthen the
ties between the GPS positioning and timing communities and their relationships with the
navigation communities.  This responsibility is being implemented by FGCS through its role
as the GPS Interagency Advisory Council (GIAC) to the Department of Transportation
Pos/Nav Executive Committee and subsequent reports to the FGDC Steering Committee.  In
the GIAC role, the membership has been instrumental in influencing GPS modernization,
especially in its recommendations regarding selection of the new civil GPS satellite signal

<BR WP="BR1"><BR WP="BR2">
<P><FONT FACE="Times New Roman" SIZE="-1"></FONT>9. 	Collaborative Partnerships:  How many major partnerships with others do you have on this
theme?  (list if desired)</P>

<P>	- California Spatial Reference Center (CSRC)</P>

<P>	This partnership was established to provide the geodetic services necessary  to ensure the
availability of consistent, accurate, and timely spatial referencing data for California.  The
CSRC consists of representatives from the public government agencies (Federal, state, and
local), universities, utilities, and the private sector.   </P>

<BR WP="BR1"><BR WP="BR2">
<P>	- Louisiana Spatial Reference Center - In development, similar to CSRC.</P>

<BR WP="BR1"><BR WP="BR2">
<P>	- National CORS</P>

<P>	National CORS is a network of Global Positioning System (GPS) continuously operating
reference stations (CORS), that provides support for accurate 3-dimensional GPS positioning
activities throughout the United States and its territories.  The National CORS network
benefits from a multi-purpose cooperative endeavor involving many government, academic,
commercial, and private organizations.  New sites are evaluated for inclusion according to
established NOAA criteria.  The National CORS is currently growing at a rate of three or
four sites per month.  Surveyors, GIS/LIS professionals, engineers, scientists, and others can
apply CORS data to position points where GPS data have been collected. </P>

<BR WP="BR1"><BR WP="BR2">
<P>	- Cooperative CORS</P>

<P>	Cooperative CORS, a complementary network to National CORS, was developed and
brought into operation.  Cooperative CORS provides greater access to more CORS data and
to encourage the use of positional coordinates consistent with NSRS.  Standards and
specifications were developed to provide standardization and consistency among providers of
GPS base station data.  Similar to National CORS, these stations are provided through
partnership with a variety of providers.  Cooperative CORS differs from National CORS in
that the provider archives their data and has more flexibility in operation time.  Both have
there data made available through the Internet by NGS.</P>

<BR WP="BR1"><BR WP="BR2">
<P>	- GPS Crustal Motion Monitoring</P>

<P>	FGCS members collaborated the University NAVSTAR Consortium (UNAVCO) in a plate
tectonics study in the Northwest and Alaska, investigating the use of GPS in monitoring
crustal motion.</P>

<BR WP="BR1"><BR WP="BR2">
<P>	- Federal Base and Cooperative Base Geodetic Control Networks </P>

<P>	State and local surveying organizations co-observe with federal field parties and assist in
accelerating completion of the improved height component of the Federal Base Network
(FBN).  Those organizations that follow NGS specification and procedures can expect to
achieve the same height accuracy for their Cooperative Base Network (CBN) stations as
obtained for the FBN stations.  When NGS specifications and procedures are followed, NGS
processes, adjust, archives, and disseminates the results for those CBN stations, without
charge. </P>

<BR WP="BR1"><BR WP="BR2">
<P>	- Electronic Distance Measuring Instrument Calibration Base Lines</P>

<P>	This cooperative program provides surveyors with a means to detect and correct errors in
Electronic Distances Measuring Instruments (EDMI).  More than 300 EDMI Calibration Base
Lines (CBL) have been established throughout the United States in cooperation with various
government agencies, universities, professional societies, and the private sector.  These
highly accurate base lines provide a locally accessible standard for length measurement. For
each state, users are provided with location descriptions and the adjusted results of calibration
base line measurements.</P>

<BR WP="BR1"><BR WP="BR2">
<P><FONT FACE="Times New Roman">	- Geodetic Instrument Tests</FONT></P>

<P><FONT FACE="Times New Roman">	FGCS coordinates and conducts inter-agency tests of new geodetic surveying systems,
including the instrumentation, hardware, software, and procedures that comprise that system. 
This testing process is recognized by surveying equipment manufacturers and users as the
Federal assessment of how well tested equipment will meet performance requirements
specified in surveying contracts.</FONT>  The equipment used in the tests is provided by private
industry as well as personnel who take part in evaluation process.</P>

<BR WP="BR1"><BR WP="BR2">
<P>	- Remote Sensing Calibration and Evaluation Networks</P>

<P>	FGCS is developing and will manage a set of remote sensing calibration networks to be used
by companies acquiring remotely sensed data to calibrate their LIDAR, Hyperspectral, SAR,
and aerial Photography systems. Remote sensing evaluation networks will also be established
to appraise the processes in which those systems are used.  Private industry will provide the
equipment and the personnel to carry out the systems calibration and evaluation.</P>

<P>		</P>

<BR WP="BR1"><BR WP="BR2">
  <LI> Scope:  Are you engaged in broad participation and international/global coordination?</LI>

<P>		Through its membership, FGCS is engaged with the following international

<P>		International Association of Geodesy</P>

<P>		International Earth Rotation Service</P>

<P>		International Federation of Surveyors (FIG)</P>

<P>		International GPS Service for Geodynamics</P>

<BR WP="BR1"><BR WP="BR2">
<BR WP="BR1"><BR WP="BR2">
<P>11.  Policy:  Do you have a policy in place for full and open access or data sharing?</P>

<P>	The FGCS charter states: "<FONT FACE="Times New Roman">Develop, adopt, publish, and promote common standards of
content, format, and accuracy for geodetic data for use by all Federal agencies and to
encourage use by non Federal organizations, to increase its interchangeability and enhance its
potential for multiple use.", constitutes policy encouraging open access and data sharing.</FONT></P>

<BR WP="BR1"><BR WP="BR2">
<P><FONT FACE="Times New Roman">	The National Geodetic Survey has a policy regarding publication of data sheets for National
Spatial Reference System (NSRS) geodetic control points.  Distribution is restricted to
unclassified, nonproprietary, data within the United States, its territories and protectorates. 
Exceptions for publishing foreign data held in NSRS are made on a country by country
consent basis.</FONT></P>

<BR WP="BR1"><BR WP="BR2">
<BR WP="BR1"><BR WP="BR2">
  <LI> Are there areas or issues regarding lead responsibilities for spatial data themes that require
