DIGITAL CARTOGRAPHY AND THE GEOSCIENCES

"Cartography is the art and technique of map reproduction. It is in a narrower sense to be characterized as a refining process between the original source material and the reproduction."
(Eduard Imhof,1962)

A map is a scale representation of a geographical environment.

The purpose of a map is to provide a meaningful picture of reality. A map, therefore, can be a particularly useful guide in the orientation of terrain, as well as conveying other multi-faceted information through supplementary annotations.

The map is the basic feature for numerous applicationsin the Geosciences: Geology, Tectonics, Geophysics, Seismology, Geothermics, Geomorphology, Geochemistry, Volcanology, Marine Sciences, etc.

Digital Cartography involves the creation and analyses of maps through the use of computers. As such, Geographical Information Systems (GIS) are an integral tool for Cartography.

Various Thematic and Ortho-photo Maps (using the Arc/Info and ArcView GIS software packages) were created, following the demands of Cartography (e.g. scale, generalization, map projections) in the Space Applications Research Unit during the last few years (see also GIS 0n this site).
