Geodata @ The British Museum Enriched archaeological records Daniel Pett email@example.com / @portableant finds.org.uk
Recording: one chance Our staff generally have one chance to record Dissemination online is swift, cheap, easy There is no other archaeological database of this size It is underused for research at present The data it contains can tell a thousand stories of our shared heritage
Objects referencing place:The Staffordshire Moorlands trullaThis is a list of four forts located at the western end of Hadrians Wall;Bowness (MAIS), Drumburgh (COGGABATA), Stanwix (UXELODUNUM) andCastlesteads (CAMMOGLANNA). it incorporates the name of an individual,AELIUS DRACO and a further place-name, RIGOREVALI. http://www.finds.org.uk/database/artefacts/record/id/49791
Why is the spatial data so important?Without provenance: A museum cannot acquire an object Is it looted? Did the landowner give permission? Context has been lost, we don’t know thesignificance of the location of discovery.

All objects we have recorded• 1997 – 2010• Topography is an issue• Landowners and regulations can prevent discovery• Biases present in data collection eg. Staff illness, lack of car etc etc
Using YQL• Reverse geocode for WOEID for each findspot against flickr.places• Get flickr shapefile if exists for WOEID• Obtain a co-ordinate for findspots where only place is known (lower weight for academic use though).• Obtain elevation via the geonames api (for viewshed analysis – surprisingly good!)• Find objects within bounding boxes• Query for archaeology images on flickr
Display problems• Public users can only see find spots at a resolution of 1km sq or 4 figure NGR• Some find spots have to be hidden from public view completely – we give a place a pseudonym• Maps make our finders and landowners jumpy• Zoom level had to be reduced for public users• WOEID can give away find location
Re-use of OS and EH point dataBoth of these datasets came as CSV, now converted from grid refs to Lat/Lng andWOEID (and also elevation for centre point) if anyone wants them.
What archaeologists would like: A database of places – ancient & modern?• Ancient place names – Dates in use – Co-ordinates at that time – Affiliation (political) – Example database – Pleiades, NYU http://pleiades.stoa.org/• Modern place names
