Measuring Preferences for Natural Landscapes
In land-use planning decisions must often be made about the preservation or development of natural landscapes. The research described in this paper sought a way to measure these preferences....

Remote Sensing Sensors for Environmental Studies
The application of multispectral photography and thermal line scanner imagery to the data collection procedure for highway environmental impact studies is evaluated. The photography and...

Gravel Size Analysis from Photographs
Gravel sizes measured from photographs of river beds are biased estimates of size when compared to standard sieve analysis. Mean apparent short axis size (for gravel coarser than 8 mm)...

Wetland Surveying and Mapping
Wetland definitions are reviewed and procedures explained for surveying and mapping wetlands. Satellite multi-spectral scanners, aerial photography, and land survey methods are mentioned....

Mapping Little Blue Run Impoundment Project
Project mapping may require substantial time when planning and scheduling the design and construction activities for a large project. The multifaceted Little Blue Run Stackwaste Impoundment...

Mapping America is Never-Ending Task for USGS
For its first topographic surveys, begun in 1879, USGS measured distances by counting revolutions of a wheel, ran traverses by chain and compass, and used a barometer to determine elevations....

Visualization in Turbulent Flows

IE Applications to Precast Erection Project
Industrial engineering techniques are applied to a precast concrete erection project in an attempt to increase the erection efficiency. Preplanning, work improvement methods, time-lapse...

Channel Erosion in Southwestern Louisiana Canal
Geomorphic processes active in the man-made Southwestern Louisiana Canal are studied with the aid of color infrared and multiband imagery aerial photography and various field analysis...

Mini-Format Remote Sensing for Civil Engineering
Information (data) acquisition is an important part of civil engineering practice, especially in the preparation of environmental impact assessments. The mini-format remote sensing system...

Seasonal Aerial Photographic Mapping of Galveston Island

Coastal Zone Information from Aerial Photography

What is the Future for Commercial Mapping Firms—
Historically, the traditional demarcation between government mapping and commercial mapping has been at the 1:24,000 scale topographic map. Larger scale mapping for commercial, city, county,...

Rapid Monitoring of Coal Refuse Embankments

Aerial Photography — From Balloon to Rocket
Aerial photography began long before the Wright brothers first flew an airplane in 1903. Lifted aloft by balloons and/or kites, cameras snapped aerial photos of Paris and Boston as early...

Hydrographic Surveying Turns to Electronics
Traditional technique for measuring water depth is to use a lead-weighted line. The tag line, stretched along the water surface so soundings are made in orderly fashion, can be dangerous....

Measuring Watershed Land-Use Changes with Airphotos
Aerial photographs were used to determine land-use changes over a 25-yr period in two watersheds in western South Carolina. The North Tyger River watershed near Spartanburg, S.C., experienced...

Classification and Analysis of River Processes
Aerial photographs and brief field visits are frequently the only data sources for the preliminary design of river engineering works in romote or undeveloped areas. Even if short-term...

Remote Sensing of Turbidity Plumes in Lake Ontario
Space imagery and high-altitude photography provide an effective method of monitoring the dynamics of turbidity plumes in Lake Ontario. The Niagara River plume, as much as 200 sq miles...

Cavitation from Surface Irregularities in High Velocity
Irregularities in flow surfaces of hydraulic structures operating at high velocities have been the source of serious damage by cavitation. The types of surfaces often encountered in construction...
