A Methodology to directly input data from an uncontrolled aerial photograph into a vector based geographic information system

Creator:: Sneed, Jacquelin M.
Abstract:: Historically the U.S. Forest Service has used uncorrected aerial photographs to delineate proposed and past management activities on the land base it manages. Transferring a boundary from an image not planimetrically correct to a planimetrically corrected image introduces errors. Positional accuracy of boundaries affects the number of acres the Forest...

Equal contrast tint progressions for computer cartography

Creator:: Bernert, Joseph A.
Abstract:: A psychophysical bisectioning experiment was performed to evaluate equal steps within tint progressions on a high resolution graphics terminal. In the bisectioning experiment each respondent partitioned a tint progression by interactively defining colors that were perceptually equidistant between two previously defined colors. Twenty test subjects performed the test on the...

Geographic information systems : suitability to a land use planning problem

Creator:: Harmon, Robert C.
Abstract:: Geographic Information Systems (GIS) is a burgeoning field with its roots in geography. It is increasingly being used by a large variety of disciplines, including land use planning, as a decision support tool to help solve complex spatial problems. At Oregon State University, researchers have developed an analog model which...

A translator program converting a digitized map into the format of the American proposed standard for digital cartographic data

Creator:: Langen, Gido
Abstract:: The American Proposed Standard for Digital Cartographic Data presents the new national exchange format which allows the transfer of spatial data among parties that may use different computer hardware and different operating system software. A translator program for the conversion of the AutoCAD DXf data structure to the Standard's output...

Airborne videography as a classification and validation technique for Landsat TM-based vegetation mapping

Creator:: Barrett, Charley, 1965-
Abstract:: The Oregon Department of Fish and Wildlife's (ODFW) Ecological Analysis Center (EAC) is in the process of creating, from Landsat Thematic Mapper (TM) imagery, a vegetation map of Oregon that will meet the latest standards set by the National Gap Analysis Program. Since field verification is often expensive and by...

Cartographic and projective techniques for a Corvallis area electrical load forecast

Creator:: Troseth, Steven
Abstract:: The Corvallis area study is made to help evaluate the local need for additional system capacity ten years in the future. The product of the study is an areally detailed projection of electrical demand. The demand is derived in two steps: the location, nature, and intensity of specific land uses...

The influence of map complexity on interpolation accuracy.pdf

Creator:: Young, Brian K.
Abstract:: In this paper "map complexity" refers to the inherent intricacy of a mapped geographic pattern. Map complexity and sample size are two variables shown to influence the accuracy of interpolated dasymetric maps. An automated experiment was designed to investigate the precise relationship among map complexity, sample size, and the accuracy...

Small circle subdivision method for development of global sampling grid

Creator:: Song, Lian
Abstract:: Modern environmental monitoring and modeling requires a good global grid system for survey sampling and accurate, spatially complete data collection of relevant environmental phenomena. A prime requirement for the global grid system is that the global sampling grids be regular and equal in area and have minimal shape distortion. None...

Computerized delineation of watersheds using digital elevation model data

Creator:: Flewelling, Douglas Mark
Abstract:: A method for delineating watersheds by computer using digital elevation model (OEM) data is presented. The five steps in this process are detailed and examples are shown. The algorithm was tested using a manually created OEM for a small area in Northern California. Three basins were delineated using the delineation...

The use of remote sensing in an integrated approach for stress detection on the cultivated cranberry

Creator:: Thoma, Michael N.
Abstract:: Remote sensing is an attractive method for the detection and monitoring of crop stress. The feasibility of using remote sensing for the detection and monitoring of fungal diseases, insects, weeds, and non-infectious diseases affecting the cultivated cranberry (Vaccinium macrocarpon Ait.) is evaluated. A study on the fungal disease twig blight...
