Spatial Data Transformation: Feature Attribute Conversion Issues and Practical Experience

Abstract

The need exists for continued development of spatial data transformation tools to provide increase capabilities for conversion of both format and content of locational coordinates, feature attributes, and ancillary information. Although individual geographic information systems (GIS) often provide a means of data import from and export to various other systems, such as capabilities typically only permit transformation of the spatial data structure and format from one system to another. Existing feature attribute information is essentially transferred intact, subject to the constraints of the conversion software and other characteristics of each of the conversion software and other characteristics of each particular GIS; thus, reconciliation of differences due to variations in data description are left to the user. The tremendous growth in spatial data holdings constructed using a broad range of evolving systems, techniques and specifications has intensified the demand for enhanced data transformation capabilities to facilitate the integration of numerous existing data bases.
