BACKGROUND There are many systems currently marketed that handle geographic data. They have existed long enough to generate databases of significant sizes. It follows that the usefulness of being able to accept data from existing database and distribute data to other systems is well recognized. With the practice of data exchange has come frustration. Most of those who have tried to accept data from an outside source have found that the process usually takes much longer than planned. Also, the converted data requires a significant amount of additional processing before it can be integrated into the target system. This paper argues that the problem of information transfer is being addressed at the wrong level and, that this is the primary reason for limited success with the process. What is required is the ability to convert application models; what is provided is data translation. To support this argument, the modelling process is examined from the application level through to the data format level. Data translation and data standards are discussed in light of the modelling process and a set of specifications for information exchange is presented. APPLICATION MODELLING An application starts with a real world process. To use the computer in the analysis of that process, a model must be created. From the application, application entities must be extracted and appropriate GIS constructs assigned. Each GIS construct has data models and each data model has many different formats that can be used to represent it.
