Methods for symbolic spatial reasoning requires quite often a representation of the objects in multiple resolutions. The traditional methods are in such cases less useful since the objects are either represented in a resolution of an order that is too low or they are based on a structure that does not easily allow the representation of the object in a symbolic or a qualitative way. The approach taken here has been to develop an approach that shares some of the characteristics found in resolution pyramids and quad-trees resulting in a structure represented in terms of symbolic tiles. This symbolic structure can be used for spatial reasoning in applications where, among other things, the purpose is to reason about object shape and relationships where the objects need to be represented in multiple resolutions.
