摘要: This paper focuses on the nature of error in spatial databases and implications this for data transformations GIS applications. It describes an propagation research paradigm as information flow linking successively more formal components a context. These include development conceptual models error, creation indices to measure databases, implementation mathematical functions transform model it is processed, evaluation gain insight into utility used measurement propagation.
