On the second level of legend groups of landform were
characterised according to their morphometrical expression:
lowlands to high mountains, and according to genetical
differentiation: glacial forms, fluvial lacustrine, etc.
Scale of map determines that only the laraest groups of landforms
have been presented.
Interpretability of Landsat Mosaics for Mapping.
Landsat images and mosaics were used primary for the
regional, geomorphological analysis. The main obiective of
the analysis was the identification, on the base of detectable
indicators, of structural, pertoaraphical and floristic varian-
ces, which together with climatic factor determine the indi-
viduality of morphological units. Procedure of image interpre-
tation led to the delineation of morphological boundaries and
to qualitative characteristic of individual units.
Morphological interpretability of Landsat mosaics varies
according to the dissection of terain and amount of direct,
structural and lithological informations, detectable by
manual techniques. More reliable, structural informations,
related to pattern of fractures and lineaments, were used as
primary indicators.
Lithological differentiation is more obscure by the masking
effect of vegetation and by the locally thick layer of weathered
rocks, particularly well developed in the frost rubble zone.
The correlations between lineaments, detected on the mosaics
and the structural elements,identyfied by geologic field work,
and presented on geological maps, were used for interpretation
of those lineaments or fractures which were not recognised by
conventional geologic survey. Newly detected lineaments and
their spatial distribution, were used as important factor
in delineation of morphostructural units.
In the analysis of acumulative and accumulative-denudatio-
nal relief, indirect line of deduction and criteria of
associations between physiographical elements and pattern
of Landsat image, were most useful methodological clews.
Interpretation procedure has been carried out on the mosaics
and individual images. The advantage of mosaics result from
their comprehensiveness and synopsis , which allow to perform
regional analysis faster, and to see better spatial relations
between categories of relief and morphostructural regions.
In the interpretation procedure complex of indicators; ton,
texture, pattern, associations, have been applied, and the
basic procedure was to some extend similar to the one used
in interpretation of conventional aerial photographs. Important
difference in interpretation resulted from the small scale
of images and variations of physiographical elements in vertical
