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...

Evaluating the effectiveness of illuminated and shadowed contour lines

Creator:: Eynard, James D.
Abstract:: Illuminated contour lines, where line width and color are varied based on an angle of illumination, date back to the mid-nineteenth century, but their effectiveness compared to conventional contour lines has not been fully examined. Currently, illuminated contour lines are not widely used in computer-based cartography because they are not...

Geographic information systems : some considerations for use in geographic research and analysis

Creator:: Herstrom, Andrew A.
Abstract:: The major considerations for acquiring and using a geographic information system (G..I.S.) for regional or national geographical research and analysis are examined in this paper. After defining what a G.I.S. is, some of the more practical and useful functions of a G.I.S. in day-to--day geographical work are outlined. Finally, the...

Expert systems in computer cartography

Creator:: Ulshoefer, Veit Stefan
Abstract:: The purpose of this paper is to describe the application of expert system concepts to cartographic problems. Expert systems, a subfield of artificial intelligence, are computer programs based on knowledge and symbolic reasoning. The basic principles of expert systems will be explained. Areas of cartography that are most suitable for...

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...

Automated Layout of Origin-destination Flow Maps : U.S. County-to-county Migration 2009-2013

Creator:: Stephen, Daniel M.
Abstract:: Visualizing large movement datasets with flow maps is difficult because overlapping flows create significant graphical conflicts that make accurate interpretation difficult or impossible. Interactive flow mapping applications allow users to explore large movement datasets by automatically generating flow maps from subsets of the data in response to queries by the...
