Currently, geodetic control data are generally available
only at the federal level. The National Geodetic Survey
(NGS) publishes only the results of those surveys that their

The advantages of a state office which would disseminate
NGS control data as well as all other survey data within the
state are discussed. Since NGS now distributes its data on
floppy diskettes, the design of a microcomputer database to
access this information is investigated.
This thesis focuses on such a database system operated mainly by the end—user of control data. An integrated software system, in which. related computational programs are linked to the database, is also considered. The dBase III
package, as one software alternative, is examined. Applicability to geographic information systems is also explored.
Data formats, file sizes, and administrative concerns are
dealt with, and future research and development in these and
related areas are proposed.
