With the development of 3S and information technology,more and more programming languages and platforms have rushed,which mainly leads to the incompatible and redundant between software.Model driven architecture(MDA) has tried to give a way to share the programmers' diligent work,and unified modeling language(UML) is used to standardize the process of software development.With the base of unified data criterion architecture and information code architecture,the geologic hazards are analyzed and geologic information models are preliminarily designed in this paper.By efficiently and visually analyzing and processing of geologic information with spatial distribution characteristics,the system are validated with good prediction and preparedness of geologic hazards.
