Title

Data integration in a GIS : the question of data quality

Abstract

As Geographical Information System (GIS) databases have become progressively larger and more complex and increasingly unconstrained by traditional geographical boundaries, data management and quality have merged as critical issues in GIS projects. GIS technology can be considered as a table-top on which data are compiled, considered, manipulated and located. Discusses the problems associated with obtaining data of an appropriate standard from within the institutional framework of local government and the data quality problems inherent in the development of an integrated database with reference to the development of a geographic database for a loosely defined subregion of the South East of England, the East Thames Corridor
