Analysis of Discrete Entities in Space 29 April 2002 SP02 –CE608 1 Analysis of Discrete Entities in Space Data retrieval & analysis ? User has a problem or query ? Database contains information that can be used to answer the problem ? Maps, tables or figures ? Data base ? Presentation ? Recall the data ? Compute new information ? Display the results – visualize the information Basic data models ? Entities in space ? Attributes, location & connectivity of the entities ? Measures way they are distributed in space ? Continuous variation of an attribute over space ? Spatial properties of the fields ? Complicated as use triangles or grids to discretize the continuous data

• buffer zones around an entity
• attributes of multiple entities
• basic classes of data analysis for entities
• numerical model of a physical process
• entities with respect
• discrete entities
• spatial entities
• geographic location
• attributes
• operations
