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....

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...

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...

Right-of-Way Surveys
Cooperation in Reconnaissance Surveys; Utilization of Aerial Photography and Photogrammetric Maps in Preserving the Location of Survey Monuments; Preservation of Monumentation; and Right-of-Way...

The purpose of this investigation is to describe and demonstrate the reliability of using aerial photographic interpretation as one of the fastest and most economical methods of locating...

Intertidal Communities as Monitors of Pollution
Ecological surveys of the intertidal zone are proposed as being the most economical way in which the biologic impact of many wastes discharged into the estuarine and coastal marine environments...

Infrared Aerial Surveys in Environmental Engineering
To obtain full advantage of the techniques involved in remote IR sensing, the basic principles related to the nature of IR radiation and the problems associated with its atmospheric attenuation...

Profiles of the Round Turbulent Jet in A Cross Flow
The shape of a jet issuing normal to a uniform cross wind has been studied experimentally for a large range of jet-to-wind velocity ratios, R,...

Mapping Standards for Urban Planning
Accurate and up-to-date surveys and maps are essential for community planning, but available mapping is not meeting the requirements of planners. Better coordination and integration are...

Apollo Lunar Landing Site Selection Process
The selection of potential lunar landing sites for the Apollo Program poses some unusual problems. Among the factors to be considered are geographic location on the moon, surface topography,...

Mapping for the Pennsylvania Highways
The methods and procedures currently used by the Pennsylvania Department of Highways to obtain mapping by photogrammetric methods are presented. Map scales for various engineering functions...

Flow of High Expansion Form in Pipes
The results of tests of the flow of high expansion foam in smooth and rough pipes are presented. It is concluded that foam is non-Newtonian with pressure loss a function of average velocity...

Nomenclature for Bed Forms in Alluvial Channel, Report of the Task Force on Bed Forms in Alluvial Channels of the Committee on Sedimentation
This paper is the report of the Task Force on Bed Forms in Alluvial Channels, Sedimentation Committee, Hydraulics Division. A collection of definitions developed by the Task Force is presented...

Remote Sensing for Estimating Soil Salinity
Cotton was used as an indicator plant to relate the salinity in the 0 to 5 ft profile at some reference locations to that at a number of prediction sites where the salinity was unknown....

High Density Vehicular Flow-Density Relationship
Experimental research was conducted on vehicular flow-density-speed relationships for conditions ranging from maximum flow to jam density. Investigation was made of the applicability of...

Report on Pipeline Location
This Report on Pipeline Location is devoted primarily to suggested procedures related to cross-country pipelines: reconnaissance, location,...

Pipeline Location: Specifications For Aerial Photography: Progress Report of Task Committee on Pipeline Location
A specification is presented that outlines, in detail, the most common photogrammetric services used in pipeline location. Aerial vertical photography, negatives and prints, and indexes...

Photogrammetric Measurement of Tidal Currents
