An inventory of existing land use maps developed by Oregon county planning departments has been made through use of questionnaires and interviews. The degree of consistency has been examined with regard to the types of base maps, scales, projections, base information, and classification schemes employed. Recommendations have been made for...
For many years, psychologists have studied
the principles of psychophysics. Recently, cartographers
have been considering psychophysical theory in
color attribute analysis to aid in the design of maps.
An experiment was conducted using the partitioning
method by which the Munsell value scale was determined
to find (R,G,B) coordinates giving equally...
The development of a geographic information system
(GIS) requires the development of large databases of
spatially related information. Scale, resolution and the
classification of thematic data can vary considerably in
terms of the level of detail at which the data are compiled
and converted to machine readable form. The level...
When the Spatial Data Transfer Standard is adopted as a Federal
Information Processing Standard, a Quality Report containing sections on lineage,
accuracy, logical consistency, and completeness will be required of agencies
producing digital cartographic data. This Quality Report diverges significantly from
the "U.S. National Map Accuracy Standards", in place for...
Attempts to map the distribution of acidic
deposition have been inadequate, particularly in areas of
seasonal or limited rainfall. Ambient air concentrations
of acid precursors may be used to monitor and map the
distribution of potential acidic deposition. A network of
stations in California currently monitor these ambient air
concentrations....
High resolution land use/land cover information from
stream riparian areas is useful in understanding instream
biotic assemblages, and is often not available for
geographical research. A classification system was developed
which provides the types of information about the riparian
buffer thought to be important in providing good habitat for,
or...
The main theme of this research is the application of geographic techniques in a study involving environmental monitoring and analysis of the associations between landscape and in-stream characteristics in the Pacific Northwest. The geographic techniques used in this study include (1) geographic information systems (GIS) coupled with statistical analysis and...
This paper explores the use of hypermedia m geographical and environmental analysis, focusing on the use of sound. After providing essential definitions the paper presents a brief history of multimedia and hypertext (the combination of which lead to the term hypermedia) and object oriented programming. The concept of the hypermap...
Cartographic generalization results In locational Inaccuracies of the
generalized feature. The cartographer expresses the amount of generalization
and the locational inaccuracy of the feature through map design and choice of
map scale. This information is often lost when the map is digitized. In the environment
of geographic Information systems, the...
Vegetation along the banks of mountain streams in the western Oregon
Cascades comprises an integral part of the transition zone between land and
water based ecosystems, and as such, is a vitally important and unique natural
resource. Forestry is a major land use in this region, and harvesting riparian
vegetation...
