Abstract
Spatial data is essentially different from transactional data in its nature. The objects in a spatial database are distinguished by a spatial (location) and several non-spatial (aspatial) attributes. For example, an astronomy database that contains galaxy data may contain the x, y and z coordinates (spatial features) of each galaxy, their types and other attributes. Spatial datasets often describe geo-spatial or astro-spatial (astronomy related) data. In this work, we use a large astronomical dataset containing the location of different types of galaxies. Datasets of this nature provide opportunities and challenges for the use of data mining techniques to generate interesting patterns. One such pattern is the co-location pattern. A co-location pattern is a group of objects (such as galaxies) each of which is located in the neighborhood (within a given distance) of another object in the group.
