Explicit Approach to Exterior Orientation
Until recently, exterior orientation methods, which have made their debut in photogrammetric literature, have been developed by treating the problem as a nonlinear one. Therefore, iterative...

Television Display of Topographic Maps
Television is ideally suited as a cockpit display device in air navigation and as a real time communication link in a topographic data bank. Resolution and geometric fidelity are the two...

Photogrammetric Surveying in Highway Program
Solutions to certain complex problems involved in the location and design of modern freeways in urban and rural areas, by use of aerial surveys and photogrammetry are considered. Procedures...

Remote Measurement of Radial Deformations
In the process of performing the triaxial test it is sometimes required to find the amount of lateral strain at various stages of the test or to prevent lateral strain. This note demonstrates...

Modern Day Surveys for Highway Location and Design
Spin-offs of space technology and defense oriented research projects present the highway engineer with adequate means of surveying to demand requirements. Descriptions are presented for...

New Zeiss Electro-Optical Instrumentation
In map production a relatively large part of the total expenses are spent for the field survey. Contrary to photogrammetric procedures field surveys could hardly utilize the modern achievements...

A New Philosophy on Preservation of Survey Evidence
Land surveyors are obligated to the public to advise some means to preserve and perpetuate land survey evidence. Many surveyors consider the placing of durable monuments as the only method...

Analytical Plotter System
The analytical plotter, model AP/C, is a highly precise photogrammetric instrument used as an investigating or engineering tool, or both. Civil engineers utilized the instrument in the...

Instant Relief with New Stereo Image Alternator
The recent development by the U.S. Geological Survey of Stereo Image Alternator (SIA) Illumination Systems for photogrammetric stereoplotters promises to extend the useful life of optical...

Construction Control by Photogrammetric Methods
Modern photogrammetric techniques can be of tremendous assistance to the survey engineer by furnishing a network of control points with positions and elevation values for convenient survey...

Mapping for Changing Environment
Topographic maps provide a vital inventory of man's physical environment. A vast effort is required to acquire this inventory and keep it up to date. To meet the burgeoning...

Computer Programs for Strip Aerotriangulation
A FORTRAN IV computer program was developed for each of the following three methods of strip aerotriangulation: (1) fully-analytical; (2) instrumental; and (3) semianalytical, by independent...

Photogrammetric Mapping of Craters from Small Explosions
The possible future use of nuclear explosives for large-scale excavation projects has led to small-scale investigation of cratering and ejecta mechanisms using chemical explosive charges....

Fifty Years in Surveying - Mapping - and the Future
The tools and techniques of surveying and mapping have undergone revolutionary changes during the last 50 years. Automatic levels and electronic distance-measuring instruments have simplified...

Geodesy and Photogrammetry in the 1960's
The basic geodetic control network in the United States includes about 100,000 monumented first- and second-order horizontal control stations that are accurately related one to another,...

Photogrammetry for Right-of-Way Acquisitions
The reasons for using photogrammetry are presented; its limitations and advantages are discussed. The use of positional uncertainty is recommended as the basis of the accuracy evaluation...

Photogrammetric Measurement of Structural Movements
Photogrammetric measurements of displacements of architectural and engineering structures require relative measurements between pairs of plates photographed at different times with the...

Determination of Perspective Generating Parameters
A photogrammetric method for the determination of the generating parameters of a photograph is presented. The generating parameters are defined as six independent coordinates from which...

Inertial Platforms in Photogrammetric Mapping
The inertial platform has been used in photogrammetric mapping to give the direction of the vertical at the moment of exposure in addition to the horizontal position of the camera. Conclusions,...

Close-Racing Photogrammetric Data Reduction Scheme
The described data reduction scheme evolved in the course of research work on the development of data acquisition systems for strain and deflection measurements of structural models under...
