Archaeology Underwater: The NAS Guide to Principles and Practice

POST-FIELDWORKANALYSIS AND ARCHIVING 183

As a general rule, such drawings should be organized
according to scale – from large-scale, site-location map to
close-up plans of specific parts of the site or sections of
a deposit. They should be presented and captioned in such
a way that cross-referencing between the site master-plan
and details is easy. Off-site information, such as the
results of survey work around the main site, may also be
included.
It is advisable to keep all drawings free from unneces-
sary information. Location maps are more effective when
uncluttered with roads, buildings or anything else not

directly relevant to the subject (figure 19.2). If drawings

become cluttered or confused, it might be appropriate to

create overlays (drawings showing the same main features

but providing different details). This can be particularly

useful in terms of presenting results (e.g. of magnetome-

ter or probing survey, or the location and extent of any

trenches excavated). Changes in the nature of sediment

across a site can also conveniently be shown in this way.

The important point to remember about such overlays

is that common control points (chapter 14) linking them

to the master-plan or section must be clearly marked.
