A desk-based assessment, or desk-top usually forms the first stage of an archaeological assessment, although this type of research may, on occasion, be undertaken in isolation.
A variety of sources will normally be consulted in a number of different repositories. The principal sources of information are usually historic maps, most commonly the Ordnance Survey 1st and 2nd editions of the later 19th century, the Tithe Surveys, enclsoure maps and estate maps, the latter often providing the earliest cartographic depictions of an area. Photographs can also provide useful information, and for rural areas in particular the succession of vertical aerial photographs by the RAF and Ordnance Survey can often prove invaluable.
Visits will usually be made to consult the regional Historic Environment record and the National Monuments Record, as well as the National Library of Wales and regional record offices.
