beams. Another representative elements are the carvings on the
centre roof bars.
Fig.5: Fale afolau
A different shape shows the so-called “Fale Tele”, the “Big
House”. It is an approximation to the type of the “Round
House”. But its unique construction progress from top to bottom
shows, that it is not really a round house, but a further
development of the Fale afolau that rectangular centre is
minimized to three centre poles. As that construction is that
special it is explained here.
Fig.6: Construction of a Fale Tele
At the beginning a temporarily scaffold supports the positioning
of (mostly) three centre poles. Really eye catching are the
bindings of coconut fibre, which are used for the assembling of
all parts of the construction. The characteristic shape of the roof
forms out of the bending of the wooden rafters with the help of
a second scaffold. The positioning of the border stacks
completes the construction of the centre part. Next the apses are
erected. Auxiliary scaffolds stabilize the hanging construction
during the building progress.
A very important element of the Fale is the platform of stone. It
functions as a protection against bugs and humidity. Apart from
that the height of the platform serves as an architectural element
of representation.
The procedure of the construction of a self-sufficient hanging
roof is unique for a wooden skeleton construction. It is an
example for the highly developed
2.3 Expedition photogrammetry
Using the “3x3 Rules for Photogrammetric recording of
architecture” different buildings where documented in a
photogrammetric usable way. The task was to hand out the 3x3
rules to students of architecture and find out if the explanations
are clear to receive sufficient results without too much support
from photogrammetric experts. At first the first point for the
geometric rules had to be enlarged for the description of the
planning of the pictures for the interior of a building. The figure
below shows a recommendation for the Fale afolau.
Traditional welcome rules and customs did not allow taking the
pictures at best light conditions. So - funny to watch for the
villagers - the students walked around in groups of three: one
with the camera, one drawing the sketches and one protecting
the camera against back light with an umbrella.
Other aggravating circumstances were the heat, tropical rain
showers and the narcotising effect of the welcome drink
“Cava”. Some missing pictures and large picture scale now and
than resulted of the unusual conditions. But within the progress
of the journey and with some routine the recording results
improved.
Fig.8: Taking pictures
Students of Photogrammetry and Remote Sensing produced the
photogrammetric computation at the University of Technology
Vienna. The program “ORPHEUS” was used for measurement
and orientation.
Following procedure was used and can be recommended for
further computations on similar objects:
To start with the definition of a local coordinate system by
using shapes (x-y - plane, z - axis) with many points. After that
a sub block should be adjusted sharing points of the definition
of the coordinate system. To adjust the entire block a
consecutive adjustment is advised always adding one or two
further neighbouring pictures into the adjustment.
Fig.9: Photomodel of the Fale
Students of architecture finally measured the points and plotted
the wire model of the object. The co-operation between students
of different subjects offered them the possibility to learn the
needs and work of the other disciplines. In that way better way
for interdisciplinary communication shall be opened for future
tasks.
The measurement and the computation of the example above
showed again the complexity of the work with amateur
photogrammetric recordings. With the growing market of digital
cameras and rising interest of people in cultural heritage there is
a growing demand for the engagement with the
photogrammetric restitution of amateur recordings.
