Sea coast, Places like Prerow, Born and Wiek, but also the
network of roads and lanes and details of the coastal and
bodden landscape are well identifiable even in a composite
colour presentation,
2, Standard composite colour presentation is particularly
Suited for interpreting such terrain where there is little
or no knowledge of ground truths.
For example, Fig, 4 shows multiband photos of the Pamirs
and Alai Mts., taken from Soyuz 22 at a height of 265 km
and covering an area of 120 km x 170 km = 20,400 qkm.
Channels > (540 nm), 3 (600 nm) and 6 (840 nm) were se-
lected for additive colour presentation on the screen of
the MSP-4 and coded with blue, green and red colour fil-
ters, respectively. In this standard method, the resulting
colours resemble those recorded by conventional false
colour film, with vegetation appearing reddish, while
rock and sand are pictured in various blue and green hues.
The vegetation was studied mainly to detect alpine range-
land suitable for pasturage; but the primary purpose for
photographing the region was the exploration and monitoring
of glaciers, Before, about 30 glaciers had been known in
the region; 80 more were located from the MKF-6 photos.
This allowed to draw conclusions on the hydrology of the
region.
3. For specifio interpretation tasks, special colour presen-
tations can be composed to enhance colour contrast between
objects little differenciated on standard colour composites.
By combination of negatives and positives in composing
colour presentations on the MSP-4 screen, colours can be
changed to the effect of enhancing contrast, especially
for individual objects such as in settlement areas
(Fig. 5). For comparison, fig. 6 shows the standard com-
posite image of the same area, Another example proves that
contrast-enhancing changes can also be obtained by varying
the colour codes in parts of the picture. Fig. 7 shows the
Selenga river (Siberia) where it flows into Lake Daikal.
In the right-hand section, the zone of water-born sedi-
ments has been clearly emphasized as compared to the
standard composite image (centre). The farmland in the
left-hand section shows grain crops of different kinds
and maturity stages up to harvesting.
The above two examples are images composed of three or
four spectral ranges, respectively. The technique called
sandwiching employs all six ranges. From channels 2, 3
and 5 (positives) and 1, 4 and 6 (negatives), three
congruent negative/positive sandwiches are formed in order
to achieve a specific colour differentiation. In Fig. 8,
the technique is used to assess the soil humidity of farm-
lands, which is an indicator to the growth and vigour of
vegetation, Special colour presentations are of interest
also for geological, hydrological and environmental studies,
