Our heritage and archaeological experience includes mapping finds, digitising historical information and analysing historical change. We are currently working (with GeoData) helping English Heritage understand and improve heritage data management across the organisation. In 2003-4 we also undertook a similar review for National Trust for Scotland, developing their GIS strategy. Most notably we have been supporting the University of Winchester to map and analyse historical trade from Southampton between 1430 and 1540, and provided the maps for a subsequent book .
