A Qualitative Representation Of Spatial Scenes In R2 With Regions And Lines, Joshua Lewis
A Qualitative Representation Of Spatial Scenes In R2 With Regions And Lines, Joshua Lewis
Electronic Theses and Dissertations
Regions and lines are common geographic abstractions for geographic objects. Collections of regions, lines, and other representations of spatial objects form a spatial scene, along with their relations. For instance, the states of Maine and New Hampshire can be represented by a pair of regions and related based on their topological properties. These two states are adjacent (i.e., they meet along their shared boundary), whereas Maine and Florida are not adjacent (i.e., they are disjoint).
A detailed model for qualitatively describing spatial scenes should capture the essential properties of a configuration such that a description of the represented objects …
