The U.S. Geological Survey side-looking airborne radar database: an aid to the interpretation of space images

The U.S. Geological Survey (USGS) has a database of side-looking airborne radar (SLAR) images of a significant part of the continental United States. These images provide a regional view of terrains and should be an aid to better understanding image data of satellite synthetic aperture radar (SAR) and other systems. The USGS has been systematically collecting SLAR since 1980, initially in analog form, then in both analog and digital format since 1984.

U. S. GEOLOGICAL SURVEY'S SIDE-LOOKING AIRBORNE RADAR PROGRAM: THE ALASKAN CONNECTION.

The U. S. Geological Survey (USGS) has become a major source of side-looking airborne radar (SLAR) data as a result of a Congressional mandate in 1980 to 'begin the use of side-looking airborne radar for topographic and geologic mapping, and geological resource surveys in promising areas, particularly Alaska. ' In 1982, SLAR images were acquired, with a northwest look direction of almost 13,000 km**2 of the Aleutian Islands. Although acquisitions in succeeding years concentrated on selected areas of interest in the conterminous United States, Alaskan radar data will again be collect in fiscal year 1986. Mosaics have already been prepared for more than 20 percent of the conterminous United States and 10 percent of Alaska. Although mosaics are a convenient form of compiling radar images to provide a synoptic view, the individual radar strips, especially film transparencies, have considerably more detail and are used for most serious studies.

MAJOR SOURCE OF SIDE-LOOKING AIRBORNE RADAR IMAGERY FOR RESEARCH AND EXPLORATION: THE U. S. GEOLOGICAL SURVEY.

The US Geological Survey (USGS) instituted a program in 1980 to acquire side-looking airbore radar (SLAR) data and make these data readily available to the public in a mosaic format comparable to the USGS 1:250,000-scale topographic map series. The SLAR data are also available as strip images at an acquisition scale of 1:250,000 or 1:400,000 (depending on the acquisition system), as a variety of print products and indexes, and in a limited amount in digital form on computer compatible tapes. Three different commercial X-band (3-cm) systems were used to acquire the imagery for producing the mosaics.

DATA ACQUISITION AND APPLICATIONS OF SIDE-LOOKING AIRBORNE RADAR IN THE U. S. GEOLOGICAL SURVEY.

The Side-Looking Airborne Radar (SLAR) program encompasses a multi-discipline effort involving geologists, hydrologists, engineers, geographers, and cartographers of the U. S. Geological Survey (USGS). Since the program began in 1980, more than 520,000 square miles of aerial coverage of SLAR data in the conterminous United States and Alaska have been acquired or contracted for acquisition. The Geological Survey has supported more than 60 research and applications projects addressing the use of this technology in the earth sciences since 1980. These projects have included preparation of lithographic reproductions of SLAR mosaics, research to improve the cartographic uses of SLAR, research for use of SLAR in assessing earth hazards, and studies using SLAR for energy and mineral exploration through improved geologic mapping.

MAJOR SOURCE OF NEW RADAR DATA FOR EXPLORATION RESEARCH.

In 1980, the U. S. Geological Survey (USGS) initiated a program to acquire high-quality, side-looking, airborne-radar (SLAR) imagery of selected areas of the United States. The program goals were to demonstrate the usefulness of SLAR imagery for geologic exploration and geoscience applications and to make radar data readily available to the public for additional research and economic applications. Considerable SLAR imagery has been acquired already since 1980 under a mandate from the U. S. Congress. The U. S. Geological Survey is actively engaged in demonstrating the usefulness of radar imagery, and since 1980 has started more than 50 studies addressing geologic, cartographic, and hydrologic applications. All of the radar-imagery products acquired by the USGS during 1980 and 1982 have been archived and are available for public sale.

Review of the stratigraphy and structure of the Gubik anticline

At the direction of Ralph L. Miller, a special study was made of part of the Gubik anticline east of the Colville River. The purpose of this study was two fold; first, the examine the field evidence bearing on east plunge, second, to attempt to establish the continuity of the anticlinal axis from the Colville River to the Anaktuvuk River. The results of this study and a summary of results of the study of part of the anticline west of the Colville River by Stefansson and Thurrell 1/ are presented below.
