Evaluation of the improvement in sensitivity of nested frequency plots to vegetational change by summation 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...

Use of slope, aspect, and elevation maps derived from digital elevation model data in making soil surveys 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...

Testing the consistency for mapping urban vegetation with high-altitude aerial photographs and landsat MSS data 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...

Using a spatial and tabular database to generate statistics from terrain and spectral data for soil surveys 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...

Tetlin National Wildlife Refuge land cover mapping project users guide 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...

Design of a spatial data structure using the relational normal forms 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...

Higher resolution satellite remote sensing and the impact on image mapping Higher resolution satellite remote sensing and the impact on image mapping
Recent advances in spatial, spectral, and temporal resolution of civil land remote sensing satellite data are presenting new opportunities for image mapping applications. The U.S. Geological Survey's experimental satellite image mapping program is evolving toward larger scale image map products with increased information content as a result of improved image processing techniques and...
