The design of GIS math-model base system based on meta-algorithm

Mathematic Algorithms were used in every part of GIS.However, with the development of GIS, existing organizing and managing methods of Mathematic Algorithms can't satisfy the developing need, especially in the sharing, expendability and flexibility of models.Through researching the methods of describing model, this article put forward a new concept called which can instead of model granularity to increase the flexibility of models.Based on Meta-Arithmetic and the hierarchy between models organizing by Object Oriented approach, we research the classification of Meta-Arithmetic in GIS, then build a Math-Model Base System Based on Meta-Algorithm, and introduce the processing of making a new Arithmetic Model integrally.Through studying, the conclusion is that, using Math-Model Base System to manage Math-Model is a effective method to manage arithmetic models,which is useful to realize the modularization and practicality of data- processing which GIS is dealing with.
