The ‘spatial wealth’ of the Museum’s collections is often ignored or at best under-appreciated. Most specimens if not all have a spatial locality associated with them, either written on to a label, written in a notebook, or on the specimen.

These localities can vary between very precise (e.g. a GPS-based latitude/longitude), very imprecise (e.g. ‘South America’) or, most likely, somewhere in-between. Most specimens within the Museum do not have a latitude and longitude, but do have detailed locality information on the accompanying label, which can be used to define co-ordinates for that specimen. So what is georeferencing, why do we need it, and how do we use it?
