Once a feature has been excavated, not only do the samples and finds need to be correctly labelled, but the feature itself needs to be recorded. This is done by firstly taking photographs and then by creating a record in the way of a scale drawing and making detailed notes on an A4 context sheet. Sections across a feature are usually drawn at a scale of 1:10, plans at 1:20. Recording was at times a little tricky on site at #InnovationParkMedway, particularly in the bad weather last winter. Wind, rain and paperwork do not go together very well!

Luckily, we didn’t need to draw many plans at Rochester as they were surveyed in by Senior Archaeologist Matt, who had access to our new top of the range surveying system, the Leica GS18 Rover.
Matt really enjoyed using this for the first time and describes how it works…
"This is a GNSS (Global Navigation Satellite System) device which uses a network of orbiting satellites to ascertain its position to under 1cm accuracy. This allows us to map quickly and accurately where archaeology is on the ground and to plan excavated features in fine detail. Using technology such as this, we are able to provide both accurate, up to the minute, mapping information to site managers and to begin the process of post-excavation while still on site. This allows us to be more efficient and to make decisions based on real-time data."
