The BioGeomancer Project is a worldwide collaboration of natural history and geospatial data experts that, among other things, is developing the BioGeomancer Workbench - a set of tools to facilitate georeferencing of natural history data. The tools being developed include data quality, validation and cleaning tools that identify outliers and possible errors in georeferenced (latitude and longitude) data and altitude using a range of methods. Methods vary from simple statistical outlier tests through to the use of climate-based environmental modelling. The tools are being integrated into both on-line Web-Services as well as stand-alone tools such as Diva-GIS. This paper will discuss how these tools work, and how they are being integrated into the BioGeomancer Workbench.

We acknowledge support of the Gordon and Betty Moore Foundation, and all collaborating experts and their institutions. Partner institutions will soon be listed on the forthcoming BioGeomancer web site.
