Conclusions
In this article, new methods for processing, modelling, reconstruction, anal-
ysis and visualization of the vanished landscape are implemented. These
methods for processing old maps and aerial photographs were tested in a
wide range of areas (see Site 1 to Site 6). Each of the processed data sources
required very special handling to obtain sufficient results like the right choice
of georeferencing method, identical point selection or defined work-flow for
processing old aerial imagery.
Modelling, reconstruction and analysis are dependent on the quality of the
input data. Digital terrain modelling or digital surface model derivation from
the processed aerial imagery is very sensitive to input errors. The resulting
georelief reconstructions will be an important part of the information system
when printed on a 3D printer, as well a part of an exhibition. A detailed study
of the resulting DTMs and DSMs precision is currently under development.
Other types of reconstruction (hydrology network, or land-use for example)
will be a part of the information system as well.
New methods of vanished landscape visualization were tested within this
project—aerial imagery taken from a KAP (Kite Aerial Photography) or a
UAV (Unmanned Aerial Vehicle) are bringing a very new point of view on all
localities. These methods allow us to obtain orthophotos or oblique
