Abstract
Contemporary cartographic production requires working with databases, of various
topographic and thematic structures, which must be standardized and with the possibility
of converting values from one data type to another. In order to better map out the reality,
in the modeling process, the geodata are systematized within the databases, graphically
integrated in regard to thematic significance (primary and secondary). Cartographic
methods of geo-visualization offer numerous solutions for interactive visual
representation of thematic content. Adjusting the graphic representation and ways of
interaction while using the cartographic models allow the visualization of the "hidden"
content provided by geodata. By integrating standardized data, in the framework of a
database (classification, standardization ...), besides the basic cartographic representation,
the interconnected and conditioned additional and supplementary, synchronized graphical
representations of the cartographic issues can be realized. Synchronized representations
can originate from the same database as the basic map or they can be made by combining
data from multiple different databases (with the ability to manipulate within the same
formats, classifications, standardizations ...). In doing so, the interactive capabilities in
manipulating the maps must be well thought out and evaluated. The approach, ways and
limits of database manipulation, as well as the offered cartographic visualization
solutions, should provide users with highlighting of the most important aspects of the
representation. The coordination of different, but synchronized representations is enabled
by visual integration of geodata, in order to create a geo-visual environment in the context
of understanding large amounts of data (content, space and time). A complex structure of
geodata can be cartographically integrated and presented if it is adapted and based on the
principles of cartographic generalization and cartographic design. The content
generalization on a model can be the following: taxonomical, spatial, attributive and
graphical. The content generalization and symbolization of the thematic maps are key
procedures for geo-visualization. The degree of generalization (geometric and semantic)
influences the degree of data integration that are graphically represented.
