The World Wide Web is a promising new media for cartography. It allows the creation of interactive maps that can be accessed by the general public. There is a wide variety both in methods used and in the overall quality of current Web sites. This report reviews the state of...
The visualization of climate patterns is a major theme in cartography. Short-term
dramatic weather events such as hurricanes and tornado outbreaks are mapped and
displayed immediately in order to capitalize on the sensational nature of the events, and
to quickly and accurately convey the information to emergency workers and the...
This study provides some guidelines using and comparing the
RGB (red, green, blue), HSV (hue, saturation, value), and HLS (hue,
lightness, saturation) color specification systems to help designers
of computer produced layer tinted maps to select appropriate and
effective colors from the immense palette provided by modern color
monitors. Map...
In this work software is developed to take an ecosystem management tool used by the US Forest Service, the Ecosystem Management Decision Support (EMDS) system, and enhance its utility by capturing the results of an ecosystem assessment and saving them in a format that facilitates importation into other management tools,...
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...
ArcView 3D Analyst is a powerful geospatial tool, and has proven very useful in
3D visualization and analysis. In most cases, 3D data models are temporally static,
representing only one instance in time. For many applications, the 'missing' time
dimension is of great significance, and there is a need to...
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...
With increased attention being focused on the remaining old-growth
forest resource in the Pacific Northwest a way to ecologically rate forest stands is
needed to assist the U.S. Forest Service in its management decisions. A Geographic
Information System (GIS) model was developed to rate old-growth stands in a 49,500
acre...
A program, Color Choropleth Mapping System (CCMS), has
been developed to provide high quality color choropleth maps at
the Geography Department at Oregon State University. The program
operates interactively and is menu-driven. When developing the
software for mapping programs, programmers need to be aware of
cartographic theory, as well as...
The density at which urban areas are developed has become a contentious issue, with
advocates for compact cities in conflict with advocates for larger lots and suburban
development. This research paper examines the associated impact of population density
(grouped by residential zones) as measured by vegetation (Normalized Difference Vegetation
Index)...
