The Concept and Application of Point Resource System Object Model
点源理论目标的概念和应用

Starting with understanding the origin of the world,this paper points out a conceptual model of concrete and active theory object Point Resource System.Raw and compound Earth Observing Image Information(Remote Sensing GIS) is understood and processed according to the concept of Conformity Congregate Information Field and Discrete Object.Purposeful object information with definite boundary and position information is obtained by the size of the point source.What's more,several application tools point resource vary scale model,point resource retrieval model and point resource earth surface characteristic model have been implemented to fulfill the extraction and process of mass data information until the procedure of info storage and info retrieve is formed.
