Ghazi M. Rayan,Joseph Upton III GIS application domains, different approaches have been taken in representing spatial and non-spatial data. As we have already mentioned in Chapter 1, two major types of representation methods for spatial data are called . and . based representations. Field-based representation methods capture the

In field-based representation, the geographic space is partitioned (tessellated) into cells that are disjoint and that collectively cover the entire geog

In order to systematically study the various issues related to spatial query processing, we start with query processing in traditional database applications and then identify the extensions and modifications required to accommodate spatial queries.
