As we have already mentioned in Chapter 1, two major types of representation methods for spatial data are called . and . based representations.

In field-based representation, the geographic space is partitioned (tessellated) into cells that are disjoint and that collectively cover the entire geog作者: 機(jī)警 時(shí)間: 2025-3-22 06:46 作者: 傻 時(shí)間: 2025-3-22 08:52 作者: alleviate 時(shí)間: 2025-3-22 16:25

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.作者: alleviate 時(shí)間: 2025-3-22 18:48

Ghazi M. Rayan,Joseph Upton III models can be further subdivided into fixed and variable spatial resolution models [Laurini and Thompson, 1992]. Fixed spatial resolution models use a geographic data structure called a ., which consists of polygonal units of equal size. These units are used to describe geographical features.
