“Collocation is a derivation of several typematic features of spatial objects”. A general mathematical definition can be given to the collocation as just a variable therefore possessing more than one quality that belongs to a spatial object. However, the spatial object is a finite set of features, except that the features change when there is a major/great change in the spatial domain that is engulfed in the spatial object. The change of features does not affect much the collocation, only except there is a great phenomenal change. The collocation will provide all the necessary feature set required for the expression of the spatial rule. The spatial rule defines the core of knowledge patterns in the spatial domain. The knowledge patterns can be applied to mine the quality of a spatial domain. The spatial rule carves up into spatial association rule and collocation rule. A seamless definition of a collocation rule is a set of features that belongs to a set of spatial objects prevailing in the spatial domain that describe the knowledge pattern.
