CPAT has extensive experience in undertaking detailed topographical surveys of archaeological sites and wider landscapes. Over the last 15 years our staff have undertaken a wider range of surveys, including prehistoric stone circles, Iron Age hillforts, Roman forts, deserted medieval settlements and 19th-century mining landscapes.
Surveys are undertaken using a digital laser theodolite in conjunction with the latest survey software. The resulting data can be used to produce traditional contour information, as well as digital terrain models.

Interpretation of earthwork remains is a key element of all topographical surveys, and this can often be aided by evidence from desk-based research, such as early maps and aerial photographs. In other instances the results may be combined with those from geophysical survey to provide a more detailed analysis of a particular site.
Recent surveys have included Penycloddiau Hillfort in the Clwydian Range, which identified numerous eathwork platforms for round huts, and Shrawardine Castle, near Shrewsbury, where a combination of topographical and geophysical surveys revealed several phases of development.
