Appropriate Methods of Recording in Archaeology and for Conservation ...
525
Documentation in archaeology means in the ideal sense three-dimensional recording and thereafter simulation of excavated (and
mostly removed) setting. Technically speaking we are far away from any such recording. At least with 3D recording by total-station
and its software an approximation can be obtained.
Documentation in archaeology also means recording of structure surface textures like material patterns of walls (brick, stone etc.).
Here the texture as a pattern is of primary importance, not its precision in measurement. Instead of time consuming traditional hand
measurements, simple approximate photographic recordings with their electronic interpretation may under specific conditions lead to
better, faster and more economic documentaries.
Documentation in archaeology also means administration and management of huge information data banks. Here an newly developed
databank administration system has been developed jointly with the private sector and may help in supporting a quick access to
complex data banks.
As a consequence of modern time and finance constraints new ways of rationalization also in archaeology have to be looked for.
While hardly any improvement can be envisaged in excavation techniques, definitely rationalization can be obtained in the sector of
documentation. This presentation may offer one way of doing so.
2. DOCUMENTATION METHODS AT AL-BALEED
The documentation of al-Baleed is associated with the collection of a vast amount of information from different sources. These
sources are related to the implementation of different activities for gathering information and thereby developing the park. These
activities are classified in:
Excavation
Conservation
Landscaping
Didactics
2.1 Documenting Excavation works
Excavation deals, structurally speaking, with the documentation of surfaces prior, during excavations and after excavation works; as
well with the documentation of wall structures stone by stone, horizontally as well as vertically.
The loci of objects can be easily identified by the 3-D co-ordinates of total station reading thus allowing future 3-D identification. Of
course this recording does not substitute the traditional planum- profile recording.
While methods for 3-D surface recording by total-station (Topcon, Leica etc.) have been proved to be extremely effective and
precise, plan parallel recordings with simple photography transferred into electronic recording programs has been proved sufficient in
relation to approximate preciseness for the identification and study of surface structures such as stone by stone documentations. The
same method can be applied for the recording of planum and profile with the critical re-working in the photo/ record itself.
The information gathered is recorded and produced simultaneously to the works through the use of using sustainable off-shelf
application and instruments widely available in the market, such as a Total Station, CAAD, analogue cameras, scanner, raster image
processing applications used roughly rectified photography.
2.2 Conservation Forms
The completed structure documentation of the site, prior, during and after the excavation works has permitted the preparation of a
“Conservation Manual”, which is used for monitoring the state of conservation of the different sectors or identified structures in the
site and provides strategies for adequate immediate conservation work and historic recording (See Figure 2).
