Gridded: Most frequently this type of data is output from a meteorological or oceanographic model. However, it could be any spatial point data where the points are arranged in a horizontal grid. 2. Irregular: The points have no predictable ordering. Typically, this might be observations from multiple weather stations at a given time or samplings from a survey. Temporal BLOBs were developed to address a different sort of data, specifically observations at a single point over a span of time. One could be used, for example, for storing a series of readings from a weather station or buoy.

Performance experiments show that choosing the right bounding rectangles and corresponding algorithms for grouping entries is not trivial and is dependent on the characteristics of the workloads. The long-term effect that different types of bounding shapes have on the grouping of finite line segments deserves a more detailed study. The studies of bounding shapes may be also useful in connection with the indexing of the histories of moving points, represented as polylines. REFERENCES Agarwal P. , Erickson J.

The ability to retrieve data in a semantically meaningful form: This means that the data retrieved must be structured in a meaningful way easily usable by the Spatio-Temporal Information System (STIS). Efficiency: Since the STIS must access large quantities of data the transactions must occur quickly. These criteria guarantee that the system will be able to effectively use the data it stores. The Spatial and Temporal BLOBs described here were developed for the storage of meteorological, oceanographic, and observational data and were designed with these criteria in mind.
