How accurate are the locations / co-ordinates of the archaeological / historic sites listed in the ARCHI UK datbase?

More than 85% of the sites listed in the ARCHI UK database are accurate to 6 or more figures in the UK National Grid Referencing System (eg TL 065 0227). This is the accepted accuracy for archaeological reporting with respect to the publications (eg journals, books and archaeological reports) the data has been sourced from. A 6 figure co-ordinate means that the site/find will be within the 100 metre square referenced by the co-ordinate.

As an example, consider the Priory site at TL 065 0227. On the map the marker is right on the site. However, be aware that if for example a coin is geo-referenced to 6 figures, then the coin would have been found in the 100 metre square indicated by the co-ordinate of the find.

On the Maps of Archaeological Sites, is the resolution of the marker positions based on the grid locations (typ +/-50m) or the lat/long (more decimal places)?

All the locations in the ARCHI UK database are held in the British National Grid Format. At least 85% are to 3 figures or more (many to 4 or 5 figures). Regarding the decimal lat/longs, these are all extrapolations from the NGRs with the heart of the code referencing methods associated with the Herlmert transformations ie they are of the same accuracy as the National Grid References they were extrapolated from.

Also, there is the problem of extrapolation from NGR to decimal lat/long and the inherent inadequacies associated with the translation. All the data in ARCHI is held as NGRs but plotting on the the maps requires translation to decimal lat / long.

Regarding the place-name associated with a find / site's co-ordinate, this is actually an extrapolation from the co-ordinate which is cross-referenced with my database of place-names. Hence, in some cases a site may actually be in a particular parish but because the centre of a neighbouring parish is closer, the site is 'tagged' with this place-name. Again this is because many of the sites and findspots were just recorded as co-ordinates in the original publication and the place-name has had to be calculated in order to give some measure of locational context.

If I make a donation, can I access the ARCHI archaeological site GPS locations databases

The donation buttons are generally used by people who would like to make a contribution towards the costs of providing the free services on the ARCHI website. These free services are access to the British Ordnance Survey old maps, Antique Old Maps, ARCHI UK Place-Name Finder, ARCHI Wordwide Archaeological and Historical data and maps and other free archaeological and historical research services on the ARCHI website. You do not have to make a donation to access these services but it is very much appreciated if you do as there are significant costs to cover for us to provide these free services.

Access to the UK archaeological sites GPS locations and maps does require the purchase of a subscription to the ARCHI UK database, which is current £39.95 per year.
