be unfit .Experimental work demonstrated 
that the accuracy of final results increa- 
ses two or three times if.empirical weig- 
hts are used. 
It shoud be pointed out that important 
achievements were. made in the field of 
treatment and adjustment of measurement 
information in geodetic and photogramme- 
tric networks when using the theory of 
probability and mathematical statistics. 
Consequently when we. have HARDWARE and 
SOFTWARE and in this way one can normally 
work. 
CLOSE-RANGE PHOTOGRAMMETRY 
It was necessary to carry out complex 
inventory of the most valuable historical 
architectural monuments,to do research 
work in future as well as to aid the res- 
toration in I969 a research Laboratory of 
Engineering Photogrammetry was established 
at Vilnius University and I976 at The In- 
stitute of Preservation of Monuments the 
Laboratory of Architectural Photogramme- 
try was founded. 
The first laboratory is occupied with 
provision of photographic data and complex 
inventory to the creation of photogramme- 
tric archives of valuable historical archi 
tectural monuments.The latter laboratory 
is mainly concerned with the provision of 
photogrammetric data to the architects - 
restorers,necessary for the preparation of 
restorative designs.In a period of rather 
short time the complex inventary of the 
old castles of Vilnius,Trakai,Birzai,Medi- 
dinkai,Kréva,the ensembles estates,the an- 
cient etnographic villages was carried out. 
The plotting of the ancient towns was made 
by the architectural laboratory and the 
front elevation drawings were plotted to 
a scale I:100 and the line drawings of de- 
tails were-made to an enlarged scale 1:20 
or 1:10. 
Since I980 in both laboratories worked 
out automated photogrammetric systems 
(APMS) for surveying small objects such 
as architectural monuments,landscapes and 
geological formations (architectural en- 
sembles,archeological objects,slashing 
coasts of various waterubodies,travelling 
dunes,etc.).The main base for the systems 
is photocameras,stereacomparators,PC,a 
97 
numerical coordinatograph. 
On the basis of these systems the 
first attempts to organize the establish- 
ment of digital photogrammetric archives 
of cultural monuments were made.But rea- 
lization of this idea is limitted by the 
possibilities of the technical base avai- 
lable. 
Combination of aerial and terrestrial 
photogrammetry opens wide possibilities 
in surveying archeological heritage to 
to the enviroment and enables to evalu- 
ate properly their protection. 
ACTIVITIES OF THE NATIONAL COMMITTEE 
The birthday of the Lithuanian Commit- 
tee for Photogrammetry and Remote Sensing 
is said to be 1983 there was held first 
conference on the problems of close-range 
photogrammetry; they were ihe following: 
I. The application of geodetic and pho- 
togrammetric methods in research of cul- 
tural and natural objects // Allunion / 
republican conference Vilnius .1983 ; 
2. The problems of cartography of cul- 
tural and natural monuments // Allunion/ 
republican conference Vilnius. .1989 ; 
3. The architectural photogrammetry // 
International conference .Vilnius.1I989.
