Formatted Message Exchange in a Multinational Environment.

摘要

It is important to exchange meaningful and useful data in a multinational environment. However, several nations have different data dictionary and data models. There are also cases where there are different data models in a nation, e.g. The Army data model and the Navy data model could be different for their information systems. In such cases, it is almost impossible to exchange data and utilize these data to obtain a situation display. Several techniques have been developed to take over this problem. One of them is database replication and other is the Formatted Message approach. Each method has its own advantages and disadvantages. Formatted Message Approach is used to exchange data among the different information systems in our study. We have developed an algorithm, which tries to handle this interoperability issue. In the algorithm, core software is developed which checks all the received formatted messages and corrects the possible specific errors according to ADatP- 3 rules and inserts or updates the database with this received and corrected data. Software can be thought as a gateway between the GIS application and National information systems that send formatted messages. It converts formatted messages to database entries so that GIS application can use the received data and display them.
