Henry Chapman is the Time Team Surveyor. Henry, who took over from Bernard Thomason for the 2002 series, is principally responsible for all the surveying of the excavated trenches, artefacts and the geophysics grids. This is why you tend to see him with a variety of yellow technical equipment.
The data he collects with this GIS equipment is used to create the maps which bring all the different information together in order to understand the sites investigated by Time Team. Henry also creates the three-dimensional computer models of the sites and their landscapes, working closely with Stewart Ainsworth to get a fuller picture of the landscape archaeology and the environmental development.
