Louisiana coastal GIS network: Graphical user interface for access to spatial data Louisiana coastal GIS network: Graphical user interface for access to spatial data

Louisiana's coastal wetlands support a large percentage of the nation's seafood and fur industries, vast deposits of oil and natural gas, habitat for thousands of species of plants and animals, winter nesting grounds and migratory paths for numerous waterfowl, and many recreational resources enjoyed by residents and tourists. Louisiana's wetlands also have the highest rates of coastal...

Low-flow sediment transport in the Colorado River Low-flow sediment transport in the Colorado River

In support of beach-stability research, bedload and suspended sediment were measured during a steady flow of 5,880 ft3/s and receding flows from 12,100 to 5,660 ft3/s in the Colorado River above National Canyon, near Supai, Arizona, October 7-12, 1989. During steady flows, 75 percent of the mean total-sediment discharge of 128 t/d was in suspension and about half the total-sediement load...

Major results of gravity and magnetic studies at Yucca Mountain, Nevada Major results of gravity and magnetic studies at Yucca Mountain, Nevada

About 4,000 gravity stations have been obtained at Yucca Mountain and vicinity since the beginning of radioactive-waste studies there in 1978. These data have been integrated with data from about 29,000 stations previously obtained in the surrounding region to produce a series of Bouguer and isostatic-residual-gravity maps of the Nevada Test Site and southeastern Nevada. Yucca Mountain...

Marinas, mines, and mudpots. Building a feature-based production system at the U.S. geological survey Marinas, mines, and mudpots. Building a feature-based production system at the U.S. geological survey

By the mid-1990's, the U.S. Geological Survey expects to produce spatial data according to its new data model, Digital Line Graph-Enhanced (DLG-E). This new data model currently defines more than 200 unique feature types that describe the geographic phenomena portrayed on the series of 1:24,000-scale topographic maps. Characteristics of features are encoded as attributes, and linkages...

Measuring the benefits of GIS use Measuring the benefits of GIS use

The key to objectively measuring the benefits of GIS use is to realize that there are two different types of benefits and that different techniques must be used to measure each. Efficiency benefits occur when the same task previously done without the GIS can be done less expensively with the GIS. Effectiveness benefits occur when the GIS allows completion of a task that would not have...
