The
workshop will start with a lecture showing the advantages,
the disadvantages and the many pitfalls of available algorithms
in creating a DTM/DEM. The main focus will be on the processing
of common data in archaeology: measurements coming from a
regular grid; coming from contour lines of a map; coming from
random points in the area.
After
the lecture, computers with the application Surfer 8.0 will
be available for the participants. A few datasets, from real
archaeological sites as Muro Tenente and San Pancrazio (The
Salento region in Southern Italy) and Sakkara (The environment
of the Step Pyramid in Egypt), are ready for processing, but
participants are invited to bring their own data along.
People
with own data should provide this in an Excel- or LOTUS-sheet
or an ASCII-file. The data should be organised in columns
with XYZ co-ordinates.
Please
inform the CAA2003 organisation if you intend to participate,
as the number of PC's will be limited. For questions on the
subject contact Willem Beex, willem_beex@wxs.nl.
