This Open-File Report consists of twenty-one 35-mm slides showing material that was presented at the Fourth Thematic Conference on Remote Sensing of the Environment held in San Francisco, California on April 1-4, 1985 (Purdy and others, 1985). The work was carried out in conjunction with the U.S. Geological Survey's Conterminous U.S. Mineral Appraisal Program for the Tonopah, Nevada 1° by 2° quadr

The 500 km long Gulf of Alaska coastline between Cape Suckling and Cape Spencer can be characterized by constant rapid change in an environment of glaciers, stormy climate, high relief, and extreme oceanographic parameters. During a more than 200-year history of observation, bays have completely filled with sediment, new bays have appeared, glaciers have advanced and retreated as much as 40 km, st

As a part of the National Aeronautics and Space Administration Landsat D Image Data Quality Analysis Program, the Earth Resources Observation Systems Data Center (EDC) developed procedures to optimize the visual information content of Thematic Mapper data and evaluate the resulting photographic products by visual interpretation. A digital-to-analog transfer function was developed which would prope

The mission of the U. S. Geological Survey's Earth Resources Observation Systems (EROS) Data Center is to produce high-quality photographs of the earth taken from aircraft and Landsat satellite. In order to meet the criteria of producing research-quality photographs, while at the same time meeting strict environmental restrictions, a total photographic chemical management system was installed. Thi

EROS Data Center is evaluating the geodetic accuracy of Landsat-4 data from both the Multispectral Scanner (MSS) and Thematic Mapper (TM) processing systems. Geodetic accuracy is a measure of the precision of Landsat data registration to the Earth's figure. This paper describes a geodetic accuracy assessment of several MSS and TM scenes, based on the geodetic referencing information supplied on a

Many articles have been published in the image processing areas associated with image mapping, but no document has combined these references in a single publication. Image mapping is a new and dynamic field and a baseline document reviewing past research in the image processing areas associated with it needs to be provided. A collection of annotated bibliographies provides a source for that backgr

A technique which utilizes a binary comparison matrix has been developed to implement a neighborhood function for a raster format data base. The technique assigns an index value to the center pixel of 3- by 3-pixel neighborhoods. The binary comparison matrix provides additional information not found in two other neighborhood variability statistics; the function is sensitive to both the number of c
