WINTER SCHOOL: BIODIVERSITY DATA QUALITY, DATA CLEANING AND DATA VALIDATION TECHNIQUES

14 and 15 June
Presenter:  Arthur D. Chapman (an International Expert on Scientific Coordinator of Biodiversity Information from Queensland Australia)

The ability to electronically exchange biodiversity data is leading to improved opportunities for better environmental decision making, conservation, policy and management.  However, much of the data being integrated is of varying quality and is thus of questionable value to many end users.  With biodiversity data, the quality is often dependent on two key sources of error – the taxonomic names and the locality information, including the georeferencing. This course examines the problems that are most commonly encountered and discusses ways of identifying them and correcting them in collections databases, as well as ways of digitizing information in order to reduce resultant error.  

Many tools have been developed in recent years to aid in the identification of errors in species names and these are now being incorporated as on-line data validation tools that can be used in batch format to identify errors and to provide feedback to data custodians of possible errors in their data.

This was a highly successful workshop organised by the South African National Biodiversity Institute and hosted here at the Biodiversity and Conservation Biology Department. I will be implementing some of the web-based tools in my upcoming course in Resource Mapping.
