Integrated GPS‐INS for High‐Accuracy Road Positioning
(American Society of Civil Engineers, 1992)The use of a differential global positioning system (GPS) for high‐accuracy road positioning has shown some limitations in terms of outages due to satellite masking that cause poor geometry and loss of carrier phase lock. ... -
Robust Testing Procedure for Detection of Multiple Blunders
(American Society of Civil Engineers, 1992)Blunder detection is a topic of great interest to surveyors and mappers because undetected blunders significantly distort the solution. Therefore, a robust testing procedure has been developed for the detection and ... -
Off‐Line Spatial Alignment
(American Society of Civil Engineers, 1991)A technique is developed for the three‐dimensional alignment of a straight line from stations independent of the line itself. If a line is given by two points, no instruments are required to occupy the line. Alignment is ... -
Wisconsin Public Service Corporation Geofacilities Information System
(American Society of Civil Engineers, 1991)There is a great deal of interest in geofacilities information systems (GIS's) among utilities and state and local governments since the early 1980s. GIS's are corporate data bases that maintain virtually all of a company's ... -
Using Expert Systems to Manage Professional Survey Practices
(American Society of Civil Engineers, 1992)The manager of a professional surveying practice is often confronted with the seemingly simple, but actually rather complicated, task of assigning surveying projects to different survey parties at different times. His or ... -
GIS and Transportation: Canadian Perspective
(American Society of Civil Engineers, 1991)There has been a significant interest in the application of geographic information systems (GIS) to address the special needs of the transportation industry during the past several years. Canada has been an aknowledged ... -
Institutional Issues: Local Perspective
(American Society of Civil Engineers, 1991)In direct contrast to the comments made by vendors throughout the automated‐mapping facilities‐management (AM/FM) industry, neither AM/FM nor geographic information systems (GIS) will improve existing practices, provide ... -
Experiment on Accuracy of Optical Theodolites
(American Society of Civil Engineers, 1991)Five optical theodolites of different designs and least counts are compared for accuracy in reading horizontal angles. A subtense bar of an accurately known length and a Wild T3 precision theodolite are used for this ... -
Right‐of‐Way Plats Developed on Computer‐Aided Design Drafting System
(American Society of Civil Engineers, 1991)There have been significant changes in the way right‐of‐way plats are prepared by the Wisconsin Department of Transportation (DOT) in the last 60 years and particularly over the past decade with the advent of computer‐aided ... -
Geographic Land Information Systems: State Perspective
(American Society of Civil Engineers, 1991)Geographic land information systems are being developed and implemented throughout federal, state, and local government agencies and in the private sector. The variation in how these systems are being implemented is large. ... -
Discussion of “<i>History and Method of Indian Allotment Surveys</i>” by Leroy K. Latta Jr. (November, 1989, Vol. 115, No. 4)

Discussion of “<i>Application of Graph Theory to Computer‐Assisted Mapping</i>” by Xiao‐Guang Qi and B. Kent Lall (November, 1989, Vol. 115, No. 4)
(American Society of Civil Engineers, 1991) -
Solving Circular Curve Using Newton‐Raphson's Method
(American Society of Civil Engineers, 1992)In highway, railway, canal, and pipeline locations, the horizontal curves employed at points of change in direction are arcs of circles. A circular curve can be described by seven principal elements: (1) Radius of the ... -
Delineating Theory for GPS Surveying
(American Society of Civil Engineers, 1992)The global positioning system (GPS) will have a major impact in the way we measure. It is argued that GPS will increase the public awareness for spatial referencing and that this, in addition to GPS/s technical revolution ... -
Closure to “<i>History and Method of Indian Allotment Surveys</i>” by Leroy K. Latta Jr. (November, 1989, Vol. 115, No. 4)

Geometrical Deformation Analysis of Large Concrete Roof Structure
(American Society of Civil Engineers, 1991)Deformation measurements on large man‐made structures are important, especially in the first few years after construction is complete. In this paper, after a distinction is made between geometric deformation analysis and ... -

Estimating Pit‐Excavation Volume Using Cubic Spline Volume Formula
(American Society of Civil Engineers, 1991)Current methods used for estimating the volume of pit excavation assumes that the ground profile between the grid points is linear (based on the trapezoidal rule), or nonlinear (based on Simpson's 1/3 and 3/8 formulas). ... -
New Silica Compact Tiltmeter for Deformations Measurement
(American Society of Civil Engineers, 1991)A cheap, sensitive, compact tiltmeter made of melted silica is developed for the measurement of small movements of civil engineering structures. Available surveying instruments are expensive, moderately sensitive, and they ... -
Electronic Theodolites: Comparison Test
(American Society of Civil Engineers, 1991)Six electronic, digital theodolites of different capabilities are compared for accuracy in horizontal‐ and vertical‐angle measurement. Angles of known values are observed several times using each of the test instruments ...
