| Description: | In this paper an application framework is presented, which extends the object model of an Object-Oriented CAD or GIS system by incorporating user-defined dynamic graphic symbols in its class hierarchy tree. In the proposed framework, the dynamic graphic symbols are database persistent objects of point type, defined as collections of standard graphics entities including annotation text. The symbols are associated with other graphic entities, or a data source, and incorporate intelligence on synchronizing their own contents with the current status of the source data. Standard graphics entities are used as graphics containers, while the initial contents of text entities are used as keywords to retrieve actual information from data sources or other entities. Thus, each instance of a dynamic symbol class, transforms and renders at a given position each one of the entities, for every time the map or the graphics display needs to be updated. |
