Thematic mapping from satellite imagery Thematic mapping from satellite imagery
This report, produced between 1984 and 1987 in a bilingual edition (English and French), provides a wealth of information on a wide variety of cartographic applications which are being developed to make effective use of new data that is now being collected by Earth observation satellites. At a time when natural resource development and environmental problems have to be taken into account...

Land cover mapping of the upper Kuskokwim Resource Managment Area using LANDSAT and a digital data base approach Land cover mapping of the upper Kuskokwim Resource Managment Area using LANDSAT and a digital data base approach
Digital land cover and terrain data for the Upper Kuskokwim Resource Hanagement Area (UKRMA) were produced by the U.S. Geological Survey, Earth Resources Observation Systems Field Office, Anchorage, Alaska for the Bureau of Land Management. These and other environmental data, were incorporated into a digital data base to assist in the management and planning of the UKRMA. The digital...

Toward a Federal Land Information System: Experiences and issues Toward a Federal Land Information System: Experiences and issues
From 1983 to 1987, the U.S. Geological Survey conducted research to develop a national resource data base of Federal lands under the auspices of the Federal Land Information System (FLIS) program. The program's goal was to develop the capability to provide information to national mineral-use policymakers. Prototype spatial data bases containing mineral, land status, and base cartographic...

Nowitna National Wildlife Refuge land cover mapping project user's guide Nowitna National Wildlife Refuge land cover mapping project user's guide
Title III of the Alaska National Interest Lands Conservation Act of 1980 (ANILCA 1980) established the Nowitna National Wildlife Refuge (NNWR). Section 304 of the Act requires the Secretary of Interior to "prepare, and from time to time revise, a comprehensive conservation plan" for the refuge.

Conversion of Cartesian coordinates from and to Generalized Balanced Ternary addresses Conversion of Cartesian coordinates from and to Generalized Balanced Ternary addresses
Hexagonal grids have several advantages over square grids, such as a greater angular resolution and unambiguous connectivity. The Generalized Balanced Ternary (GBT) system is a spatial addressing method for hexagonal grids in which the hexagons are arranged in hierarchical aggregates, and which accommodates vector operations in GBT space. Efficient algorithms for converting Cartesian...

An integrated approach for automated cover-type mapping of large inaccessible areas in Alaska An integrated approach for automated cover-type mapping of large inaccessible areas in Alaska
The lack of any detailed cover type maps in the state necessitated that a rapid and accurate approach to be employed to develop maps for 329 million acres of Alaska within a seven-year period. This goal has been addressed by using an integrated approach to computer-aided analysis which combines efficient use of field data with the only consistent statewide spatial data sets available...

Selected annotated bibliographies for adaptive filtering of digital image data Selected annotated bibliographies for adaptive filtering of digital image data
Digital spatial filtering is an important tool both for enhancing the information content of satellite image data and for implementing cosmetic effects which make the imagery more interpretable and appealing to the eye. Spatial filtering is a context-dependent operation that alters the gray level of a pixel by computing a weighted average formed from the gray level values of other pixels...

FOLD, federally owned Landsat data, April 1988 FOLD, federally owned Landsat data, April 1988
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.
