almost 16.000. The town is divided into 12 parts from which Klášterec nad Ohrí and
Miretice u Klášterce nad Ohrí were selected for reconstruction.
The model settlement was selected on the basis of several criteria. In the mon-
itored locality we have to be able to identify the studied factors (see below) in
the time horizons (1750, 1850, 1964, 2000 and future). Another criterion was
assumption of dynamic and heterogenic settlement development (i.e. spatiotempo-
ral developmental non-linearity), or landscape transformation determined by various
motive forces which in some cases enabled preservation of the historic features of
the settlement while in others they were concealed (cf. Andel, Jerábek, & Oršulák,
2004; Balej & Andel, 2008).
11.2.2 The Decision Triangle
We propose the term decision triangle as a representation of conditioned consensus
among three groups involved in the process of landscape planning. These groups
are representatives of the town (city), its inhabitants and finally specialists in land-
scape planning. Each within the framework of these groups has its own interests
and preferences and, of course, is not homogenous in its opinions (differences are
conditioned by education, religion, social position and many other factors). Town
representatives see their decisions of complex economic and social development of
the town, whereas the inhabitants prefer a viewpoint based on living and working
conditions, and town planners prefer long-term and extensive projects, which are
often considered apart from ecological (physical) features, processes and flows in a
landscape. Planners are often pushed into unsuitable and unsustainable projects by
politicians who - thanks to the relatively short term of office - need to present the
prompt, “visible” and popular results of their decisions.
The decision triangle should, therefore, be complex, acting and deciding together
on the basis of real landscape development scenarios. Moreover, such a mutual com-
munication should include, besides the assessment of a concrete plan, the evaluation
of direct and indirect project costs.
11.2.3 Database Creation
A database for subsequent geostatistical analysis, geovisualisation of the historic
landscape and alternative scenarios of town development was created parallel to the
selection of the model area. As regards gaining of topographical information, the
most important data sources were archive aerial photographs and cadastral maps.
The altitude data were obtained from a digital model of the territory (DMU 25) and
subsequently corrected in some locations by GPS measurements. The thematic data,
e.g. concerning the use of the land plots, buildings, quality and type of vegetation,
were obtained from field surveying and use of secondary sources (historic maps,
land registers, photographs etc.).
