Abstract (eng)
As a spherical display, the tactile hyperglobe is used for the reproduction of realistic information of spatial data. Through projection methods inside the spherical display, various global topics and phenomena are implemented and visualized. The implementation of a global story, however, is based on labor-intensive processes of data acquisition, processing and visualization. Formats used therefore are raster and vector.
This thesis investigates suitable vector formats for a planned, direct visualization on the hyperglobe. To the current state of research, global vector datasets are processed in a geoinformation system, rectified in an image processing program and imported as a flat map in raster format into the globe software OmniSuite. This process includes a lot of work. In
addition, the memory required by the rendered image data is enormous.
The direct implementation of global vector data for point datasets has already been developed and realized in OmniSuite. The aim of this work is to evaluate common vector formats, especially for line and polygon data, and to select formats for a practical analysis. There, the vector formats will be examined regarding their advantages and disadvantages in terms of their geometry, spatial reference, cartographic styling, animation, interaction, format libraries in C++ and the memory requirements.
Based on this analysis, a recommendation for a (one) vector format(s) is given. In the future, the format(s) can be used to develop a direct implementation for line and polygon datasets
on the spherical display.
