Abstract
3D and temporal objects must be included in GIS to handle real world phenomena. Many have studied extension of spatial operations
to these multi-dimensional spaces and suggested technical solutions to extend a spatial operation to a new multi-dimensional
space. These technical approaches have led to developments which can not be generalized. One technique used to extend a spatial
operation from 2D to a multi-dimensional space is not likely usable for another spatial operation, nor to extend the same
spatial operation to another multi-dimensional space. This paper suggested studying spatial operations via their dimension-independent
properties. It intends to construct a mathematical framework to integrate spatial operations of different multi-dimensional
spaces (3D and time) a GIS should support. The framework will be independent of the space in which the operations are applied
using algebraic structures - and more specifically category theory - that ignore those properties of operations which depend
on the objects they are applied to. Implementations for some case studies for spatial operations of moving points are presented.
