Visualisatie Profielen voor Geografische Gegevens - Unigis

a number of graphic parameters. When the graphic parameters are changed the
information transition will be affected.
In this research the TOP10NL product is used in a case as task-neutral
topographically oriented geographic data on which besides the traditional
1:25.000 map two other visualizations are developed. The data are intended as
a source for a cross-section of the geo-information users in the Netherlands.
The real world is viewed through topographical glasses and translated into a
more or less neutral master without thematic information added.
Below two of the three TOP10NL visualizations that are developed are shown.
A traditional TOP25 visualization and a visualization that has been based on
schoolchildren perception by using smiley symbols.

To evaluate the acceptance of a map a Visualization Evaluation Function
(VEF) has been developed. The VEF is based on the assumption that the
acceptation of the map is influenced by the used colors, symbols, information
hierarchy in relation with the relevance of the information for the user. The
VEF gives a good picture of the users. With the results of the VEF, in an
iterative approach it is possible to develop an optimal visualization that can rely
on a broad acceptance within the domain. In advance, it is necessary to get a
clear picture of the users and their wishes with regard to visualization.
The traditional Topographic visualization is for the students not acceptable.
Although the map is widely used in many professional domains it does not
speak to the imagination of the students. Further research has shown that
especially the symbols that are used for the function of the buildings are not
being recognized.
