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.
