Research on basic method of map information mining

HU Sheng-wu(School of Geodesy and Geomatics,Henan Polytechnic University,Henan Jiaozuo 454000,China)  
With the increasingly extensive application of the map as well as more and more map variety and quantity,it is very necessary and meaningful to process map information mining.We know that the expressive information of a map is composed of two parts that are the direct and indirect information.Information is directly expressed by the map graphic symbols,people can easily get it through reading cartography;indirect information is obtained by analyzing and interpreting cartography,which often requires thinking activity,such as analyzing and integrating.The paper preliminarily discusses the basic theory and method of map information mining,including the significance,the definition,and the method.With practical example,the knowledge and the application of map information mining are illuminated.Finally,it sums up the problems concerning with map information mining,and points out that map information mining is at the initial phases and need to be studied further.
