Asociación de datos espacio-temporales en bases de datos ORACLE

Geographic Information Systems (GIS) covers a set of tools for capturing, storing, retrieving, transforming and displaying spatial data from real world. Time is a dimension to model the evolution of geographic behavior. The spatio-temporal data formats like XML, KML and GML are used to store this type of behavior in geographic vectors data. The structure of GIS data currently is static; it cannot manage the dynamics and object interaction of a 3D dynamic environment which means that the integration of time-based data in GIS for simulation is complex. Some methods of discrete data storage in databases are based on describing time variations in sequences of events and time. However, some troubles were found because they do not have a unified storage structure in database management systems that support some geographic spatio-temporal formats, this could result in problems and inefficiency when distributing and reusing information. Therefore, this paper proposes a model for managing geographic data in Oracle to represent spatio-temporal formats such as XML, GML and KML. The model has tables and relations of the main elements of these formats.
