Comparing G-maps with other topological data structures

  • Patrick Erik Bradley
  • Norbert PaulEmail author


This article compares two approaches to storing spatial information: On the one hand there are topological datatypes where primitives and their connectivity are explicitly stored, on the other hand there is the G-maps-approach storing abstract “darts” and groups acting on these darts such that their orbits implicitly give the elements and topology of the stored space. First these concepts are mutually related from a categorial viewpoint and, second, their storage complexity is compared.
