2.5.2 Process Step--

2.5.2.1 Process Description-- The National Geodetic Survey
produces geodetic data. Geodetic data comprise
the results of geodetic surveys to determine,
among other things, latitude, longitude, height,
scale, and orientation control. The National
Geodetic Survey original field survey project
observations and final reports are accessioned
into records system of the National Archives and
Records Administration of the U.S.A. These
surveys provide information valuable for a variety
of uses in the mapping, charting and surveying
community.

The NGS' final product is the geodetic data sheet.
Geodetic data sheets are comprehensive summaries
of all published information for a given
geodetic reference point, including: the
geographic position and/or height based on the
current reference datum, condition of the survey
mark when it was last visited, a description of
where the point is located and how to reach it,
and an explanation of the terms used in the data
sheet. In support of these geodetic data, the NGS
provides software, publications, and various user
services, including geodetic advisor program,
instrument calibration, surveying standards, and
technical workshops.
