Junsan Zhao · Geomatics & Spatial Information Technology · 2005
The creation of the spatial database model is the base of the application of GIS. The traditional geographic spatial databases have many problems, such as the management mechanism, time dimension, the presentation of multiple scale data and so forth. To settle these problems, the conceptual models must be researched and developed. This paper discusses how to solve the problems by use of the method of UML and pictographic figures. The processes of the establishment of the models are explained in the paper. And an example is outlined to prove the usability of the method.
