Relative Error Analysis of Geodetic Networks
(American Society of Civil Engineers, 1985)Positional accuracy estimators for all the points in a primary control network are derived from the covariance matrix. Relative error ellipses in scale and in orientation are proposed as objective descriptors of the ... -
Detection and Localization of Geometrical Movements
(American Society of Civil Engineers, 1985)For the geometric analysis of deformations in survey control networks, a program system has been developed and favorably applied to detect deformations, i.e., of dams, hang slides, buildings, or earthquake faults. The ... -
BITNET: Inter‐University Computer Network
(American Society of Civil Engineers, 1985)BITNET is an inter‐university network that can facilitate the communication‐among researchers at colleges and universities throughout the United States, Canada, and some sites in Europe. This network gives users the ... -
Local Area Networks
(American Society of Civil Engineers, 1985)Local area networks will have a profound effect on the manner in which business is conducted. They will enable businesses, government agencies, and educational institutions to provide a wide variety of services by establishing ... -
Erratum: “Practical Traverse Analysis” by Wayne Valentine (March, 1984)
(American Society of Civil Engineers, 1985) -
USGS Telecommunications Responding to Change
(American Society of Civil Engineers, 1985)The telecommunications industry is undergoing tremendous change due to the court ordered breakup of the monopoly once enjoyed by American Telephone & Telegraph (AT&T). This action has resulted in a plethora of new services ... -
Foreword
(American Society of Civil Engineers, 1985) -
Accuracy and Reliability in Geodetic Networks—Program System Optun
(American Society of Civil Engineers, 1984)A program system is developed allowing the adjustment of one, two and three dimensional geodetic networks while taking into account accuracy and reliability aspects. The aims of the system are to enable the operator to ... -
Use of Computerized databases in Legal Research
(American Society of Civil Engineers, 1985)The use by lawyers of specialized national computer databases in legal research, a task basic to the practice of law, is described. First, traditional legal research tools and methods are described; then the computer‐assisted ... -
Computers and Group Communications: The Law: Forum Experiment
(American Society of Civil Engineers, 1985)Communications applications for computers include information retrieval, electronic mail, and computer conferencing. Computer conferencing is the use of the computer as a tool to facilitate communication among groups of ... -
Macrometer Satellite Surveying
(American Society of Civil Engineers, 1984)The Global Positioning System provides relative positions to 1–2 ppm with anrobservation time of 2–3 hr. The quality does not depend on weather; there is no intervisibility between stations required. The inner and minimal ... -
Telecommunications Access to National Geodetic Survey Integrated Data Base
(American Society of Civil Engineers, 1985)The National Geodetic Survey plans to implement a nationwide telecommunications network to allow on‐line access to an integrated geodetic data base currently under development. The network will use one of the commercially ... -
Computer Assisted Cartography: Graphics or Geometry?
(American Society of Civil Engineers, 1984)A classification of interactive graphic systems, currently used to prepare plans and maps in surveying practice, is presented. The first generation of systems are graphics editors storing drawings that can be graphically ... -
Role of Telecommunications in Timekeeping
(American Society of Civil Engineers, 1985)In all aspects of precise timekeeeping the efficient and timely acquisition of an increasing amount of data is becoming of vital importance. To effectively handle these data, the U.S. Naval Observatory Time Service Division ... -
Information Systems in Surveying
(American Society of Civil Engineers, 1985)The information systems of the Bureau of Land Management, Alaska State Office, are highly sophisticated and support many disciplines. One of I these disciplines deals with the management of volumes of land‐related data ... -
Field Adjustment of Tapered Shims Using a Least Squares Algorithm
(American Society of Civil Engineers, 1984)Buildings that are used in oil field operations at Prudhoe Bay, Alaska are built in warm water ports thousands of miles away. These buildings (modules) are fabricated on top of columns (stub columns) that have square flat ... -
Three‐Dimensional Adjustment Computations Model
(American Society of Civil Engineers, 1984)A three‐dimensional (3‐D) model based on the connectivity of astronomic and geodetic coordinate systems is developed from basic principles. It provides for simultaneous adjustment of most conventional types of terrestrial ... -

Inertial Surveying Systems and their Use in Geodetic Positioning
(American Society of Civil Engineers, 1984)Inertial Surveying Systems are a very recent advance in surveying technology; they are the single most comprehensive geodetic positioning tool available today. Their historical development is briefly discussed and comments ... -
Practical Traverse Analysis
(American Society of Civil Engineers, 1984)A simple approximate method of analyzing the accumulation (propagation) of random error in closed survey traverses is presented. With emphasis on the practical and approximate, a means of assessing survey quality is proposed ...
