Study on Problem-Oriented Model for Spatial Analysis Parsing in Grid Environment

This paper is purposed to discuss a problem-oriented model which can simplify the services of spatial analysis in grid environment. Based on the problem-oriented thinking, using the techniques of spatial problems parsing and operators searching, the universal spatial analysis operators are collected to solve the complex spacial analysis application and even have the decision-making responsibility. In grid environment, each technique has its own function in the grid structure of five layers. In order to satisfy the dynamic nodes in grid, use the model of Master-Worker to do the spatial analysis task of distributing and callback. In this case, the constructed model can reduce the request of professional knowledge of grid users and solve complex problems more easily and automatically.
