Differential GPS: Efficient Tool in Photogrammetry
(American Society of Civil Engineers, 1989)In the photogrammetric mapping process, a reduction of the amount of ground control can be realized when the position of the aerial camera, or to be more precise the position of its projection center, is determined during ... -
Developments of Geographic Information Systems Technology
(American Society of Civil Engineers, 1989)The development of geographic information systems, or computer systems for managing a spatial database, has been closely linked to advances in computer technology. This paper examines the hardware and software components ... -
GPS Antenna Set‐Up Procedures and Error Sources
(American Society of Civil Engineers, 1989)The significance of accurate antenna position determinations is presented. Various error sources that affect the precision of the position of the antenna phase center relative to the station mark are also presented. Field ... -
Engineering Applications of GPS Differential Surveying
(American Society of Civil Engineers, 1989)In Germany, differential GPS surveying has been used as a common measuring tool since 1983. Although there were some test measurements during the first year, GPS applications are now in a normal production phase. Some of ... -
Establishment of the Kansas City GPS Control Network
(American Society of Civil Engineers, 1989)Out of an increasing need for a reliable survey control system throughout metropolitan Kansas City, Missouri, grew the concept of regional cooperation among the area's municipalities and counties. With such regional ... -
Fundamentals of GPS Baseline and Height Determinations
(American Society of Civil Engineers, 1989)Differential GPS phase‐measuring surveys yield accuracies of a few parts per million in all three coordinates. To achieve the best results for the least cost requires careful planning of the measurement scheme. Determination ... -
GPS‐Guided Vision Systems for Real‐Time Surveying
(American Society of Civil Engineers, 1989)GPS‐guided stereo, solid‐state camera systems can perform real‐time surveying and mapping functions that are vital to the automation of many engineering processes. While GPS provides point positioning of the cameras in ... -
GPS Determination of Groundwater Withdrawal Subsidence
(American Society of Civil Engineers, 1989)Global Positioning System (GPS) surveys were undertaken in 1984 and repeated in 1985 along level lines in southeastern Arizona where subsidence induced by groundwater withdrawal was occurring. The objective of these surveys ... -
Practical Applications of Global Positioning System
(American Society of Civil Engineers, 1989)Surveying with global positioning (GPS) satellite receivers affords many opportunities to solve previously difficult surveying problems with greater speed and accuracy than may have been possible with conventional survey ... -
GPS Processing Methods: Comparison with Precise Trilateration
(American Society of Civil Engineers, 1989)Since 1982, the Geodetic Survey of Canada has been carrying out precise trilateration by electro‐optical distance measurements (EDM) incorporating atmospheric data recorded along the EDM ray path. These networks have been ... -

Surveying with Motorola Eagle GPS Receiver
(American Society of Civil Engineers, 1989)Surveying results with the Global Positioning System (GPS) have impressed those in the surveying industry because of the potential for a drastic reduction in the time and effort required for many projects. The Motorola ... -
GPS Satellite Surveys and Vertical Control
(American Society of Civil Engineers, 1989)Analysis of Global Positioning System (GPS) survey data has shown that GPS can be used to establish precise relative positioning in a three‐dimensional system. The results of many tests and operational projects have clearly ... -
Recent Advances in Kinematic GPS Photogrammetry
(American Society of Civil Engineers, 1989)The National Ocean Service (NOS) has been pursuing the application of kinematic Global Positioning System (GPS) positioning to airborne instrumentation packages and photogrammetry in particular. Two partially successful ... -

Continuous Deformation Monitoring With GPS
(American Society of Civil Engineers, 1989)The U.S. Army Corps of Engineers makes extensive use of modern instrumentation for measuring the behavior of large structures. One of these programs is high‐precision geodetic surveying. This is accomplished through the ... -
Pipeline Deformation Monitoring Using GPS Survey Techniques
(American Society of Civil Engineers, 1989)Monitoring and detecting deformations within an engineered structure can be determined using a number of precise methods. Traditional techniques for deformation detection have included: on‐site visual inspection, photogrammetric ... -
Kinematic Survey of Clinton Lake Dam
(American Society of Civil Engineers, 1989)Kinematic survey phase data are reduced using a standard double difference formulation when the initial integer values of the biases are known or determined. Two experimental results are presented. A byproduct of the ... -
GPS Geodesy and Kinematic Topography Measurements and Results
(American Society of Civil Engineers, 1989)For over 30 years Sercel has been studying and manufacturing high accuracy commercial electronic equipment used for maritime radiolocation and land surveys. To answer the present and future needs in these fields, Sercel ...
