PRINCIPLES OF DATA QUALITY
Arthur D. Chapman1

Although most data gathering disciples treat error as an embarrassing issue to be expunged, the error inherent in [spatial] data deserves closer attention and public understanding …because error provides a critical component in judging fitness for use. (Chrisman 1991).

This paper was commissioned from Arthur Chapman in 2004 by the GBIF DIGIT programme to highlight the importance of data quality as it relates to primary species occurrence data. Our understanding of these issues and the tools available for facilitating error checking and cleaning is rapidly evolving. As a result we see this paper as an interim discussion of the topics as they stood in 2004. Therefore, we expect there will be future versions of this document and would appreciate the data provider and user communities’ input.
