We have now finished digitising the Museum’s main parasitic louse slide collection – consisting of ~73,000 slides. We are sharing these openly with the global scientific community on the Museum’s Data Portal. Continue reading

Most specimens within the Museum collection have locality information, showing where the specimen was found, on the accompanying label(s). When we are digitising our specimens, we can use that locality information for georeferencing – the process used to give the locality of a specimen geographical coordinates, so that it can be plotted on a map.
This is important because it allows for mapping and modelling, which underpins research on anything from species distributions and relationships, to environmental changes or targeting conservation practices.
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?
