PDEF: A Standard File Format for Data Interchange

Abstract

The Protean Data Exchange Format (PDEF) is a set of computer programs which can be used to transform data between different systems which do not understand each other's formats. The problem of data transformation is not restricted to any particular discipline, but those of us concerned with digital terrain data have felt this problem acutely as we have found that different Geographic Information Systems (GIS) cannot use each other's data. Although PDEF was written to alleviate this particular problem. its uses are more general than the specific problem for which it was originally written. PDEF was designed primarily to be easy to use since reformatting decisions must be made by people. This report will examine both the format and the uses of PDEF.
