Measurements with a Fraunhofer Line Discriminator (FLD) imaging system over uranium-bearing sandstones in the Galisteo Formation, Sandia Mountains, New Mexico, show that luminescence of these sandstones is detectable and in general agreement with their distribution as mapped on the ground. The FLD imaging system coupled with a color television monitor and recorder, provides an...

The Earth Resources Observation Systems (EROS) Program of the U.S. Department of the Interior, administered by the Geological Survey, was established in 1966 to apply remote-sensing techniques to the inventory, monitoring, and management of natural resources. To meet its primary objective, the EROS Program includes research and training in the interpretation and application of remotely...

A legend is suggested for use with computer-generated thematic maps made from Landsat digital data that designates some of the radiometric characteristics of each thematic map unit as well as the described terrain attributes of each map unit. The relationship between spectral band and radiance for each map unit is shown by a two-dimensional polygon with the four Landsat multispectral...

The bibliography contains 82 citations of selected publications and technical reports. The references deal with the application of remote sensing techniques to the collection and analysis of geographic data. All of the citations were published between January 1968 and July 1977.

The author has identified the following significant results. The Salar of Coposa is located in northern Chile along the frontier with Bolivia. The surface was divided into six general classes of materials. Analysis of LANDSAT image 1243-14001 by use of interactive multispectral computer (Image 100) enabled accurate repetition of these general classes based on reflectance. The Salar of...

The author has identified the following significant results. The discovery of copper mineralization along a lineament mapped in Area 7 (La Paz) has lent credence to the use of LANDSAT 1 data as a basic step in mineral exploration. In Area 9 (Copiapo Region), a number of lineaments were found to be associated with the largest copper deposits of the region. In Area 12 (Magallanes), the

The EROS Data Center is a part of the Earth Resources Observation Systems (EROS) Program of the Department of the Interior, managed by the U.S. Geological Survey. It is the national center for the processing anddissemination of spacecraft and aircraft acquired photographic imagery and electronic data of the Earth's resources. The center also trains and assists users in the application of...

ERTS-1 digital data in the form of computer compatible tapes provide the geoscientist with an unusual opportunity to test the maximum flexibility of the satellite system using interactive computers, such as the General Electric Image 100 System. Approximately 9 hours of computer and operator time were used to analyze the Lake Titicaca image, 1443-14073, acquired 9 October 1973. The total...

Luminescence is the property of some materials to emit light when excited by external stimuli such as ultraviolet or visible light or by chemical or mechanical action. The Fraunhofer line discriminator (FLO) is an airborne electro-optical device which operates as a non-imaging radiometer and permits detection of solar stimulated luminescence several orders of magnitude below the...
