FOLD, federally owned Landsat data, September 1989 FOLD, federally owned Landsat data, September 1989
The FOLD data base lists all Landsat CCT's held by participating agencies. Duplicate CCT listings are maintained when more than one agency holds identical CCT's; this permits the user to select the most convenient site to obtain a copy. Copies of the listing are distributed by EDC to contributing agencies and other selected offices.

Spectral analysis and filtering techniques in digital spatial data processing Spectral analysis and filtering techniques in digital spatial data processing
A filter toolbox has been developed at the EROS Data Center, US Geological Survey, for retrieving or removing specified frequency information from two-dimensional digital spatial data. This filter toolbox provides capabilities to compute the power spectrum of a given data and to design various filters in the frequency domain. Three types of filters are available in the toolbox: point...

Terrain, vegetation, and landscape evolution of the R4D research site, Brooks Range Foothills, Alaska Terrain, vegetation, and landscape evolution of the R4D research site, Brooks Range Foothills, Alaska
Maps of the vegetation and terrain of a 22 km2 area centered on the Department of Energy (DOE) R4D (Response, Resistance, Resilience to and Recovery from Disturbance in Arctic Ecosystems) study site in the Southern Foothills Physiographic Province of Alaska were made using integrated geobotanical mapping procedures and a geographic-information system. Typical land forms and surface f...

Image processing techniques for digital orthophotoquad production Image processing techniques for digital orthophotoquad production
Orthophotographs have long been recognized for their value as supplements or alternatives to standard maps. Recent trends towards digital cartography have resulted in efforts by the US Geological Survey to develop a digital orthophotoquad production system. Digital image files were created by scanning color infrared photographs on a microdensitometer. Rectification techniques were...

Gravity anomalies of irregularly shaped two-dimensional bodies with constant horizontal density gradient Gravity anomalies of irregularly shaped two-dimensional bodies with constant horizontal density gradient
An equation to compute the gravity anomalies of two-dimensional (2-D) bodies with density contrast varying with depth (z axis) was developed by Murthy and Rao (1979). I develop an equation for computing the gravity anomalies of 2-D bodies with constant horizontal density gradient. By combining this equation with the equation of Murthy and Rao, I estimate the depth of the sedimentary...

Alaska Interim Land Cover Mapping Program; final report Alaska Interim Land Cover Mapping Program; final report
In 1985, the U.S. Geological Survey initiated a research project to develop an interim land cover data base for Alaska as an alternative to the nationwide Land Use and Land Cover Mapping Program. The Alaska Interim Land Cover Mapping Program was subsequently created to develop methods for producing a series of land cover maps that utilized the existing Landsat digital land cover...

An algorithm for locating candidate labeling boxes within a polygon An algorithm for locating candidate labeling boxes within a polygon
Vector-based geographic information systems usually require annotation, such as a polygon number or attribute data, in a suitable location within a polygon. Traditional methods usually compute the polygon centroid, test the centroid for inclusion or exclusion, and select some alternative point when the centroid falls outside the polygon. Two problems are associated with this approach: (1...

Investigations of SPOT cartographic applications in the U.S. Geological Survey Investigations of SPOT cartographic applications in the U.S. Geological Survey
The US Geological Survey has a longstanding commitment to the advancement of the technology and applications of remotely sensed data from civilian satellite systems. In the past, research based on satellite data was primarily directed toward natural resource and land use applications rather than cartographic applications. The availability of high-resolution, steroscopic data from the...
