Impact of North American Datum of 1983
(American Society of Civil Engineers, 1986)The new adjustment of the North American Datum of 1983 (NAD 83) is now in its 10th year. To understand the necessity for the new adjustment, a review of the problems encountered with the existing NAD 27 network must be ... -
Low Cost Mapping for Long Range Planning
(American Society of Civil Engineers, 1986)The PPACG, a regional planning agency, developed an intergovernmental program for joint acquisition of aerial photographs and compilation of a low cost base map. The cooperative effort of local governments provided a greatly ... -
Introduction to Expert Systems for Land Information Systems
(American Society of Civil Engineers, 1986)This paper introduces the surveying engineer to expert systems. Expert systems are computer systems that advise on or help solve real‐world problems requiring an expert's interpretation. They approach real‐world problems ... -
Utilities, Buildings, and Land Management System
(American Society of Civil Engineers, 1986)Rapid, accurate management of information regarding leasable properties and buried utilities maintenance data has been a continuing problem at many large airports. This paper describes a unique computerized solution to ... -
Roundtable Discussion on Role of Government Versus Private Sector in Geodetic Surveying
(American Society of Civil Engineers, 1986)The role of federal, state, and local governments in geodetic surveying was studied by the ASCE Geodetic Surveying Committee in the late 1970s and early 1980s. In 1984, the private sector role was also included in the study ... -
Geometry of Solar Envelopes
(American Society of Civil Engineers, 1986)With the utilization of alternative energy resources in North America have come various mechanisms for protecting access to sunlight. The mathematical aspects of the problem have not been thoroughly treated in the literature. ... -
Role of Counties in Geodetic Control
(American Society of Civil Engineers, 1986)Counties should be involved with geodetic control surveys and should maintain county‐wide information services. Such involvement should include: (1) Maintaining files of horizontal and vertical control information; (2) ... -
An Analytical Solution of the Resection Problem
(American Society of Civil Engineers, 1986)Resection, the three‐point problem, involves fixation of a new point when directions to three known points are observed from an unknown point. This paper presents an analytical solution to the problem which permits direct ... -
Expert Systems and Geographic Information Systems: Review and Prospects
(American Society of Civil Engineers, 1986)Expert system efforts of particular importance to the development of Geographic Information Systems are evaluated. Three general problem domains are identified as automated map design and generalization, terrain/feature ... -
Editor's Note

Land Information Management: A Canadian Perspective
(American Society of Civil Engineers, 1985)Canadian society is entering an era in which a dominant public issue will be the need for more careful stewardship of the land, and the more intensive management of its limited resource stocks. This in turn will require a ... -
Closure to “<i>Lake Level Effects as Measured From Aerial Photos</i>” by John G. Lyon and Ronald D. Drobney (August, 1984)
(American Society of Civil Engineers, 1985) -
Rigorous Densification of Horizontal Network
(American Society of Civil Engineers, 1986)Statistically rigorous densification of horizontal geodetic networks must consist of a simultaneous adjustment of both the densification and the densified networks. Equivalently, the effect of the already adjusted (existing) ... -
Definition of the Term Engineering surveyin
(American Society of Civil Engineers, 1985)A definition of the term “engineering surveying” is proposed in an effort to ease the confusion relatively recent developments have created with respect to the role of civil engineers in the practice of surveying. This ... -

The Surveyor and Written Boundary Agreements
(American Society of Civil Engineers, 1985)A written boundary agreement is one of several methods—parol agreement, acquiescence and acceptance, and practical location—which can be used to clarify the location of an uncertain boundary line. Unlike the other methods ... -
Kermit Protocol for Inter‐Computer Data Transfer
(American Society of Civil Engineers, 1985)To make satisfactory use of their machines, computer users must be able to send and receive files of data to and from other computer systems. Standard rules currently exist governing the hardware aspect of computer ... -
Distributed Databases for Surveying
(American Society of Civil Engineers, 1985)Space related data is gathered in different places and by different services. Considerable duplication of effort to maintain the same data is obvious. The use of a distributed database management system to manage such data ... -
Terrain Profiling Using Seasat Radar Altimeter
(American Society of Civil Engineers, 1985)The ability to remotely establish elevation profiles, especially in inaccessible areas of Alaska and Antarctica, could decrease the cost and time required to produce topographic maps. One possible means is the use of Seasat ... -
Mathematical Models within Geodetic Frame
(American Society of Civil Engineers, 1985)The geodetic frame is defined from the practitioner's point of view, i.e., the deflection of the vertical and the geoid undulation must be available for the reduction of observations. The three‐dimensional, the two‐dimensional ...
