Spatial Data Mining and its application in Marine Geographical Information System

The Spatial Data Mining as an important step of knowledge discovery process means to extract the unknown, valuable and operable relationships, patterns or trends for decision support system from large spatial databases and data warehouse. With the rapid development of marine surveying and mapping technology and computer storage devices, massive amounts spatial data appears in the Marine Geographical Information System. Traditional data processing could not discover the potential knowledge. How to make full use of the Spatial Data Mining technology to obtain the implicit rules, trends and relevance in marine spatial data becomes the most important issue on hydrographic and cartographic field. This paper introduced the basic principle of Spatial Data Mining technique, analyzed the potential knowledge which could be obtained by Spatial Data Mining, and studied the application which spatial Data Mining in marine geographic information system. It provides a new opportunity to resolve the “knowledge hunger”, and becomes a new research and development directions for current hydrographic surveying and charting field.
