Multi-source, Multi-scale Military Map Data Integration Research And Practice

The actual needs of about consociation battle and information-based war have made still greater challenge on digital map, traditional mode of taking map sheet as applied unit has not content with People's demand .People put forward the lately higher request for Consociation battle's digital map platform of Army, air force, navy. So the data integration of multi-format and multi-scale data became the initial problem for resolve of digital map platform .This paper discusses the concept of the data integration of multi-format and multi-scale data, building the frame of the data integration of multi-format and multi-scale data, and study some of theories and applications.It Includes something give below:1) Some of theories on spatial data of metadata,and the system framework for the data integration of multi-format and multi-scale data2) Introduced the spatial data model, and compared the merit and shortcoming of a few models. Buliding a fitted spatial data structure.3) Analyzed to the traditional data integration' method of multi-format and multi-scale data, based on the military, business vector data model, putting forward the method of the data integration of multi-format and multi-scale data.4) Combine physically, Carried on the concrete realization according to the above theoriesand method.
