4. CONCLUSION 
4.1 Monument protection 
Photogrammetry, remote sensing and 
cartography provide decisive aids for the 
detection and/or inventory of irretrievable 
monuments of historic importance, as a basis 
for further monument protection. 
Therefore historic maps, photos and 
measurements for this purpose in particular, 
are very valuable, but handed down texts only 
with low priority. 
The reliability for the interpretation of the 
situation of so far undiscovered monuments 
only may be judged by excavations or by 
substitutes for excavations. 
4.2 Monument Information System ( MIS) 
For a serious investigation of the reasons for 
the increasing monument dilapidation it is 
absolutely necessary, to start with an inventory 
to document the recent conditions of the monu- 
ments. 
To judge on the success of (e.g., chemical) 
measures for monument protection, a 
continuously repeating of the 
(photogrammetric) documentation of the 
condition of the monuments shall be carried 
out in future.

For a permanent availability of these results 
and also in view of the consideration of the 
monuments within environmental planning 
processes, the establishment of an up to date 
digital Monument Information System 
("MIS"), based on available GIS-Systems, like 
the ARC/Info, as already established in dif- 
ferent countries, is highly recommended.
