esolved. If resolution can not be
achieved, the question should be addressed
in the introduction with appropriate
methods for determining each
• discussed.
Obviously a tremendous amount of research
and discussion is needed to fully
incorporate high-production GPS surveying
techniques and GPS-derived
orthometric heights into a comprehensive
set of standards and specifications. Addressing
these techniques and their
viability within a revision to the existing
standards will allow individuals and agencies
to take advantage of their known
benefits, and will encourage much needed
efforts to better define their capability and
limitations. We feel that the incorporation
of these suggested revisions will help to
support the integrity of the document as a
valid guideline for modern geodetic surveying
methods.

This committee is charged with pursuing
avenues to inform our membership
regarding advances in surveying and mapping
methods, and to explore areas where
our knowledge and expertise can aid in the
implementation of new technologies. To
this goal, one of our efforts will be to collect
information from our colleagues
regarding the GPS standards and specifi-
cations and to forward this to the FGCS
for consideration. Our initial discussions
I have revealed interest and opinions from
individuals and agencies within as well as
outside of CLSA. We hope that our input
icill be found as helpful rather than complicating
an already difficult issue.
It is our sincere desire to encourage the
development and use of appropriate standards
and specifications for geodetic control
networks. In no way do we wish to criticize
the efforts of the FGCS. We fully recognize
the limited resources of the subcommittee
and the formidable task which is at hand.
This discussion is presented to express our
perception of a critical condition and to offer
these suggestions together with our interest
and support.
Thank you for your attention to this
subject.

CALIFORNIA GPS PROJECT
INDEX CONTEMPLATED
Have you ever done a control project
and afterwards found another control
project had just been completed in your
own backyard? Or have you ever examined
local control and tried to work
out an observation schedule that
would allow you rationalize the packin
to that 2nd order monument on the
mountain top? Wouldn't it be great if
you could find out who just surveyed
those two dozen B net control points in
your corner of the county?
If so, perhaps you would be interested
in the proposal set forth at the
October 17,1992, meeting of the CLSA
Advanced Technologies Committee
(ATC). The idea is to create a voluntary
registry for GPS control projects
within or adjacent to the State of California.
At present several scenarios
have been proffered for the form and
content of just such an index. Some of
the suggestions have been 1) an extensive
and very complete database
containing data such as locations, descriptions,
coordinate values, control
classifications and SPC zones of the
points in a network, 2) a list of brief
descriptions which contain the approximate
latitude and longitude of the
networks' centers, the number of
points measured and the agency, firm
or individual acting as contact for project
information and 3) graphic
tabulation of project envelopes on a
map of the State which could be available
in hardcopy or .dxf format.
If you are interested in contributing to
this central clearing house for GPS projects
and /or have surveys that you feel
would be of use in network densification,
your ideas and comments would
be greatly appreciated. Further, the
ATC would be interested in your
thoughts on presentation formats, data
you would like to see be available (and
data you would like to see NOT be
available) along with any other pertinent
information or helpful hints.
Communiques need not be fancy: a
post card will do.

President, NSPS

Dear Mr. Lomax:
I am pleased to advise you that the
delegates to the NCEES 1992 Annual
Meeting voted to ratify the
membership of the National Society
of Professional Surveyors in
the Participating Organizations Liaison
Council (POLC). The membership
is effective as of August
13,1992.
You indicated in your letter of
March 1, 1992, that Ralph Harris
has been designated as NSPS' representative
to the POLC. Unless I
hear otherwise, I will assume that
Ralph will continue as the representative.
The next meeting of the
POLC is scheduled for March 13-
14, 1993, at Salt Lake City, Utah.
The site for the meeting has not
been selected yet. The travel expenses
for your representative to
attend the meeting are the responsibility
of NSPS.
The annual membership fees
for 1993 will be $200.00. NSPS will
be billed for the fees in January
1993.
The NCEES Constitution and
Bylaws, Policy Manual, and Model
law were revised by the actions of
the delegates at the 1992 Annual
Meeting and the revised editions
will be provided to NSPS headquarters
and your representative
as soon as they are available.
NCEES looks forward to a long
and mutually beneficial relationship
with NSPS.
Respectfully,
Roger B. Stricklin, Jr.
