DB2 Spatial Extender
You use DB2 Spatial Extender to generate and analyze spatial information about geographic features, including objects that comprise the earth's surface (for example: rivers, forests, hills, deserts) and objects that occupy it (for example: cities, residences, office buildings, farms).
Spatial information includes facts such as:
- The location of geographic features with respect to one another (for example, points within a city where hospitals and clinics are located, or the proximity of the city's residences to local earthquake zones).
- Ways in which geographic features are related to each other (for example, information that a certain river system is enclosed within a specific region, or that certain bridges in that region cross over the river system's tributaries).
- Measurements that apply to one or more geographic features (for example, the distance between an office building and its lot line, or the length of a bird preserve's perimeter).
