Importance
Published, unpublished and 'grey' literature - including archaeological, historical and geological data - are all reviewed during the production of a DBA. Studies are not only undertaken to provide a preliminary view of the cultural history of a site, but also to predict the likely nature and extent of archaeological remains that survive on it. A thoroughly researched and well written DBA can save considerable resources later in an archaeological project by prioritising areas of archaeological importance or ruling out areas where archaeological remains are unlikely to survive.

Expertise
To ensure that all appropriate information concerning a site is gathered for a DBA, we can call upon the experience of archaeologists, historians, geologists and geomorphologists. ARCA staff have considerable experience in providing advice to local planning authorities, planning and environmental consultancies and archaeologists. We have particular expertise in undertaking DBAs in urban settings, where our team is used to dealing with complex written and cartographic sources from all historical periods. DBAs produced by ARCA combine thorough analysis of documentary, plan, cartographic and photographic data with detailed examination of archaeological archives. Data are integrated using geographic information systems (GIS) software, enabling us to digitally map the character and extent of archaeological remains for any given area. Following a DBA, ARCA can help to formulate strategies for the management, preservation and/or further investigation of a target site.

Compliance
All DBAs produced by ARCA are undertaken in accordance with the Institute for Archaeologists' Standard and Guidance for archaeological desk-based assessment (2008) (pdf).
