A comparison of false color composites in mapping and discriminating between salt-affected soils in Kings County, California

Creator:: Gutierrez, Carmelita
Abstract:: Spectral profiles, transformed divergence values, and feature space derived from Landsat Thematic Mapper (TM) data were used to analyze the ability of four false color composites to discriminate between different classes of salt-affected soils. To compare the spatial distribution of salt-affected soil classes, maps were generated for each false color...

A comparison of two resource evaluation models used for classifying primary and secondary resource lands in Jackson County Oregon

Creator:: Vial, John Nicholas
Abstract:: Since 1983, the Oregon legislature and the Land Conservation and Development Commission have been attempting to develop a process whereby secondary resource lands can be identified and designated. The most recent attempt at developing a secondary lands model was completed in 1990 and was tested in six Oregon Counties. Planners...

A framework for the determination of the suitability of undeveloped land in the intermountain west for use as cropland

Creator:: Rathburn, Arthur Cristen
Abstract:: The "Framework for Determining the Suitability of Undeveloped Land for Use as Cropland" is a decision-making format to assist private and governmental agency decision makers in categorizing undeveloped lands, which have been identified as having potential for conversion to cropland, as to their suitability for use as cropland. The Framework...

A georeferenced digital image analysis of micro-topographic patterns within the Willamette Floodplain Research Natural Area, W. L. Finley National Wildlife Refuge

Creator:: Anderson, Karen L.
Abstract:: The present day vegetation pattern of the Willamette Valley is a result of a long past of human alteration of the landscape. Beginning with aboriginal burning of the grasslands to present day land uses, the vegetation of the valley has been affected by anthropogenic activity. Wet prairie is a vanishing...

A geospatial data catalog and metadata management tools for the U.S. Environmental Protection Agency’s Western Ecology Division

Creator:: Bradford, David L.
Abstract:: The EPA’s Western Ecology Division (WED) had been accumulating geographic information system (GIS) data files for up to 20 years. There was no index or catalog for these files; locating data became more difficult over time. More that 4 Tb of data existed on numerous disk volumes in hundreds of...
