When the site was initially excavated by the local SCA Inspectors, they used a rolling excavation grid, placing one 10 m excavation unit besides the next. To give greater horizontal and vertical control of the site a datum and formal site grid were established in Spring 1996. A base-station for the site grid was cemented in at 5000E/3000N; a site datum was established at point and given the arbitrary elevation of 100 metres.

The area of cultural activity (ca. 600 x 600 m) was recorded using a total station, taking more than 1400 points; the area was also gridded using wooden stakes with metal tags. The co-ordinate points were downloaded from the total station into a computer and gridded on a 5 m net using the kriging option of SUFFER. The results of this were a detailed topographic map of the site (see fig. 6) and a digital terrain model.

The excavation units within the trenches are 10 m2, and each area has a local datum set in it to aid vertical control of the excavation. The excavation trenches of the Western Cemetery are tied into the site grid, the south-east peg of Square 96 was established at 3016E/5010N, and the north-west peg of Square 136 was set at 3166E/5000N. In figures 5 & 8 are shown the numbered excavation units, the season in which these units were excavated can be seen in figure 4.
