a large
spectoral
character of e;g. the LANDSAT data collecting system could
highly enhance the results = at least as regarding tecto-
nics.
The LANDSAT images available for the author do not cover the
whole area of Hungary.Just about 60 percents are to be seen
on them /Fig.l./.Unfortunately large areas are hidden under
clouds.
A great advantage is on the other hand, that the images
showing the NW-ern, W-ern and SW-ern neighbouring countries
were also available,
Thus: far-reaching connections could also be traced.
SPACE-IMAGE INTERPRETATION
At the first glance it could be seen, that an unexpected
abundance of linear features are to be seen on the image
covering the surroundings of Budapest /Fig.2./. :Soon it
turned out /just by visual interpretation/ that two main
types of linears can be distinguished: straight- and curved
ones, Some of them are tens-, or even hundreds of kms in
length.
The straight ones show a certain arrangement — it seems as
if they should radiate from a common center,/This imaginary
focus is somewhere in the Small Hungarian Plain, near GyóxK
Short parts of some of them were already known partly in
former times,
The curved ones are without exception new findings. Curvi-
linear and circular /or oval/ ones can be distinguished.
One of the most interesting curved ones is that running
parallel to the Danube in the Transdanubian area.
The most striking feature is encircling the Mátra mountains
— /See: 1 in Fig.3./ probably showing still the traces of
the original volcanic caldera.
Well distinguishable is also the buried "graben of Balaton"
/2/ never seen in such a complete mode before.
One part of the Bükk mts /3/ appears also on the picture —
with an oval shape. It resembles somewhat to the Matra,
though there is a certain difference in the geology of the
two mountains; Bükk being partly karstificated. The radial
pattern mentioned before is traceable also on the image
covering the Transdanubian Ranges /Fig.4./. In the Alps
large /Fig.5./ straight linears were discovered. These do
preform the valleys of several rivercourses /e.g. Lajta-
Mürz /1 in Fig.5./, Mura /2/ and Sava /3/.
HYDROGRAPHY IN THE XVIIth CENTURY
Instead of going into details on the overlays of interpret-
ed areas let us sketch the lines read from the map of the
original hydrography of the Carpathian basin /Fig.6./.
The map itself was compiled according to contemporary data.
