Tetlin National Wildlife Refuge land cover mapping project users guide
Title III of the Alaska National Interest Lands Conservation Act of 1980 (ANILCA, 1980) established the Tetlin National Wildlife Refuge (TNWR). 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. Before developing a plan for the refuge, the Secretary shall identify and describe--a) the populations a

Processing and analysis of commercial satellite image data of the nuclear accident near Chernobyl, U.S.S.R.
Advanced digital processing techniques were applied to Landsat-5 Thematic Mapper (TM) data and SPOT highresolution visible (HRV) panchromatic data to maximize the utility of images of a nuclear powerplant emergency at Chernobyl in the Soviet Ukraine. The images demonstrate the unique interpretive capabilities provided by the numerous spectral bands of the Thematic Mapper and the high spatial resol

Satellites sense rangeland wildfire hazard (summary)
Each day, one or more National Oceanic and Atmospheric Administration (NOAA) satellites, passing over Nebraska, beam back to receiving stations on earth an enormous amount of information about what they sense below. The Nebraska Forest Service has been investigating the possible use of some of this information to evaluate the fire danger on range and grasslands in the State. Dryness of grasses and

Use of slope, aspect, and elevation maps derived from digital elevation model data in making soil surveys
Maps showing different classes of slope, aspect, and elevation were developed from U.S. Geological Survey digital elevation model data. The classes were displayed on clear Mylar at 1:24 000-scale and registered with topographic maps and orthophotos. The maps were used with aerial photographs, topographic maps, and other resource data to determine their value in making order-three soil surveys. The

Using a spatial and tabular database to generate statistics from terrain and spectral data for soil surveys
A methodology has been developed to create a spatial database by referencing digital elevation, Landsat multispectral scanner data, and digitized soil premap delineations of a number of adjacent 7.5-min quadrangle areas to a 30-m Universal Transverse Mercator projection. Slope and aspect transformations are calculated from elevation data and grouped according to field office specifications. An uns

Evaluation of the improvement in sensitivity of nested frequency plots to vegetational change by summation
At four sites in Idaho, frequency was measured separately with three different-sized plots (10 x 25, 15 x 33.5, and 20 x 50 cm) arranged in a nested configuration. These individual frequency values were added together to create a summed “frequency.” This summed value was compared to the original frequency values generated by each individual plot size in respect to its ability to detect range trend

Raster and vector processing for scanned linework
An investigation of raster editing techniques, including thinning, filling, and node detecting, was performed by using specialized software. The techniques were based on encoding the state of the 3-by-3 neighborhood surrounding each pixel into a single byte. A prototypical method for converting the edited raster linkwork into vectors was also developed. Once vector representations of the lines wer

Design of a spatial data structure using the relational normal forms
In previous work, a relational data structure aimed at the exchange of spatial data between systems was developed. As this data structure was relational it was of first normal form, but compliance with the higher normal forms was not investigated. Recently, a new procedural method for composing fully normalized data structures from the basic data fields has been developed by H. C. Smith, as an alt

Testing the consistency for mapping urban vegetation with high-altitude aerial photographs and landsat MSS data
Two methods of analysis were evaluated for mapping urban vegetation on high-altitude, color-infrared aerial photographs and Landsat MSS data of Syracuse, NY. The first method consisted of defining the spatial patterns (strata) of urban vegetation occurrence. The second method discriminated woody and herbaceous vegetation classes within defined strata. Emphasis was placed on evaluating the consiste

Denali image map
The Denali National Park and Preserve 1:250,000-scale image map has been prepared and published as part of the US Geological Survey's (USGS) continuing research to improve image mapping techniques. Nine multispectral scanner (MSS) images were geometrically corrected, digitally mosaicked, and enhanced at the National Mapping Division's (NMD) EROS Data Center (EDC). This process involves ground cont

Innoko National Wildlife Refuge land cover mapping project users guide
Conservation Act of 1980 (ANILCA, 1980) requires the Secretary of Interior to conduct a continuing study of fish, wildlife, and habitats on the Innoko National Wildlife Refuge (INWR). Included in this study is a determination of the extent, location, and carrying capacity of fish and wildlife habitats.
