2000). Signatures used in the sheets are very comprehensive, especially from the 2nd
Military Survey. Hungarian signatures have been translated into German to make
interpretation easier.
9.3.5 Analysis
To make a comparison of old data with current land cover data possible several
utilisation classes were combined to utilisation blocks (see Fig. 9.2). Areas with
other usage contain (1) mineral extraction sites, (2) beaches, dunes and sandplains,
(3) other sparely vegetated areas, (4) bosks and groves, (5) forests and (6) different
kinds of gardens.

9.4.1 Interpretation
When looking into details of change of areas and their alteration a lot of char-
acteristic landscape changes can be seen. The built up area was similar in both
historical sheets but has increased three times (since the 1840s) and four times
(since the 1780s) respectively up to the Twentieth century for instance (see Fig. 9.2).
The traffic area enlarged five times (since the 1840s) and six times (since the
1780s) respectively of the original area, considering, that historical traffic areas were
buffered 6 m wide but today's traffic areas are often much wider.
