Lineage in GIS: The Problem and a Solution (90-6)
- Author(s): Lanter, David P.
- et al.
This paper focuses attention on a fundamental geographic structure: the GIS application. Lineage documentation specifies an application’s source data, transformations, and input/output specifications. Such information is inherently causal, communicating the theory embodied in a GIS application and the meaning of its product. A number of techniques for automating lineage information are examined. None are found to be capable of documenting data lineage.
