Assessment of impacts of proposed coal-resource and related economic development on water resources, Yampa River basin, Colorado and Wyoming: A summary
Timothy Doak Steele, Donald E. Hillier
1981, Circular 839
Expanded mining and use of coal resources in the Rocky Mountain region of the western United States will have substantial impacts on water resources, environmental amenities, and social and economic conditions. The U.S. Geological Survey has completed a 3-year assessment of the Yampa River basin, Colorado and Wyoming, where increased...
Evaluation of radar imagery for geological and cartographic applications
Gerald K. Moore, Cynthia A. Sheehan
1981, Open-File Report 81-1358
The House/Senate conference report on H.R. 4930 (96th Congress), the Department of the Interior and Related Agencies Appropriations bill, 1980, stated that the U.S. Geological Survey should "begin the use of side-looking airborne radar imagery for topographic and geological mapping, and geological resource surveys in promising areas, particularly Alaska." In...
Landsat 3 return beam vidicon response artifacts
EROS Data Center, B. Clark
1981, Open-File Report 82-803
The return beam vidicon (RBV) sensing systems employed aboard Landsats 1, 2, and 3 have all been similar in that they have utilized vidicon tube cameras. These are not mirror-sweep scanning devices such as the multispectral scanner (MSS) sensors that have also been carried aboard the Landsat satellites. The vidicons...
Image enhancement through film recorder response contouring
John E. Boyd
1981, Conference Paper, Proceedings Volume 0278, Electro-Optical Instrumentation for Resources Evaluation
In contrast to the traditional recording from high-altitude aircraft of Earth images directly onto film in their inherently continuous analog form, a Landsat Earth resources satellite samples the ground image brightness and records it on a digital, electronic medium. Although digitization incurs several extra steps in the reproduction of the...
A comparative study of linear and nonlinear edge finding techniques for Landsat multispectral data
Robert Shaw, Lynda Sowers, Ellen Sanchez
1981, Pecora VII Symposium 529-542
Several numerical methods were computerize in order to evaluate edge finding techniques for accuracy, versatility and computer time and cost. The study was preformed primarily to select edge detection operators which will be used to do spatial correlation between images for image registration of Landsat Multispectral Scanner (MSS) scenes....
The role of remotely sensed and other spatial data for predictive modeling: the Umatilla, Oregon example
Thomas R. Loveland, Gary E. Johnson
1981, Pecora VII Symposium 442-454
The U. S. Geological Survey's Earth Resources Observations Systems Data Center, in cooperation with the U.S. Army Corps of Engineers, Portland District, developed and tested techniques that used remotely sensed and other spatial data in predictive models to evaluate irrigation agriculture in the Umatilla River Basin of north-central Oregon....
Broad area forest fuels and topography mapping using digital Landsat and terrain data
Mark Shasby, Robert E. Burgan, Gregg R. Johnson
1981, Conference Paper, Seventh international symposium: Machine processing of remotely sensed data
A spatially registered digital data base of fuels and terrain information was generated for a test site on the Lolo National Forest in Montana. The data base was developed specifically for providing spatially relevant data to a mathematical fire behavior model developed by the Forest Service which integrates this information...
A Pleistocene sand sea on the Alaskan Arctic Coastal Plain
L. D. Carter
1981, Science (211) 381-383
A ridge and thermokarst-basin landscape that is strikingly portrayed in Landsat winter imagery consists of large Pleistocene dunes that have been modified by younger eolian activity and thermokarst processes. This is the most extensive area of large stabilized dunes yet reported in the North American Arctic; the...
