ABSTRACT

The topic of the conference paper is aimed to the detection and quantification of the
landscape changes identified from the aerial photos, reconstruction maps and actual
land-use. It includes also the description of the quality and structure based on landscape
indexes in a given stage and appoints at the main causes of the changes in the landscape
development.
The reconstruction maps of land use for the study area from several time horizons were
produced in order to the acquired information about the evolution of floodplain forests
in the alluvium of the Morava River. The photocopies of map sheets from the second
military (Frank’s) mapping from the time period 1836 – 1840, the photocopies of map
sheets from the third military mapping from period 1876 – 1880 or revised maps to
period 1920 – 1931, then the photocopies of the State maps of the Czech Republic
1:5,000 derived (SMO 5) from the period around 1953 were used to compile the map
sources.
The content of the above mentioned maps was transferred into the coordinate system of
the Basic maps of the Czech Republic 1: 25,000. The transfer of the map content is a
complicated, time-consuming procedure influenced by the abilities and accuracy of the
cartographers. The maps were digitalized into the thematic layers and then analyzed in
GIS environment. The visual interpretation of the ortho-photomaps gained through IMS
service of the CENIA portal helped the detection (mapping) of the selected forest
complexes in the surrounding of Olomouc. The eventual discrepancies with reality were
verified by the field survey. The results were processed in the software ArcGIS.
The aerial photos were visual interpreted and manual digitized. The created categories
of land use then entered into the landscape analyses. The interpretation of the results
from the landscape analyses is also the part of the paper.
