ABSTRACT
For three recent years the Ukrainian photogrammetrists from the Lviv Polytechnic National University have been doing wide-ranging
complex photogrammetric research at the Antarctic Station "Academician Vernadskyy". The station is located on one of the islands in
Argentine Archipelago. The main aim of our experts is to fulfill the following tasks: to get a digital map with the scale of 1:1 000 which
is to serve as a basis for GIS of the archipelago with the following indication of biologic, radiometric, magnetometric, geophysic and other
data: to monitor the coastline and to find out the dependence of the changes on the natural factors; to research the DTM structure of the
coastal glaciers, to determine the cinematic parameters (displacement) and glaciologic data.To accomplish these tasks we have elaborated
and put into practice the mathematic model of photogrammetry of cinematic processes and complex technology of conducting digital
terrestrial survey from a firm point and from a moving boat. In the course ofthe expedition period 2002 - 2004 the researchers made about
1000 digital photographs that were stereoscopically processed on the digital photogrammetric station DELTA-2. The analysis of the
digital maps and DTM proves effectiveness of technology, and accurate presentation of the changes of spatial objects. The paper includes
the photos of Galindez Island and some cartographic material got in the course of research.
THE MONITORING OF THE COASTLINE
A wide range of researches and experiments has been done at the
Ukrainian Antarctic Station "Academician Vernadskyy". Exten-
sive information collected on this region needs systematizing. This
natural requirement pushed forward the idea of making GIS ofthe
Argentine Islands and adjacent coast of Antarctic peninsula.
The topographic map with the scale of 1:1000 were chosen a basis
for making GIS because such map is very convenient to indicate in
details all the information like biologic areas, colonies of birds,
location of various sensors (radiometric, magnetometric, meteoro-
logical and the like).
To make the topographic maps we used the methods of terrestrial
phototheodolite digital survey [1].
The survey included field and cameral work. The field work aims
to obtain photographic (digital) information (a stereogram) about
the locality and data defining the elements of the absolute orienta-
tion.
The field work provided the geodetic base on the territory under
survey. The work started with surveying Marina Point from the
boat equipped with the tripod to fix camera.
However the complicated glacier situation in the year 2002 kept
us from completing the whole amount of work planned according
to the technology. So the decision was to survey the island from
the adjacent territories: Winter Island, Grotto Island, Corner Is-
land, Skua Island. To provide a complete mapping, the survey
was done in two ways: normal and with equal deviation of the
optical axis of the camera depending on basis. After the field and
cameral photogrammetry work was completed on Winter Island,
the expedition proceeded with survey on Grotto Island, interme-
diate islands and Corner Islands.
The expedition of the year 2003 finished the survey of Galindez
and Winter Island.
Some "dead" areas were found in the process of digital
phototheodolite survey of the island coastline. This necessitated
topographic photographing which was done with the use of GPS
Owing to peculiarities of the relief it was necessary to use GPS in
topographic survey of the western part of Galindez Island. Still
the planned work was not accomplished, as it appeared impos-
sible to get directly to the object under research. Then digital
phototheodolite survey was done on Penguin and Penjuin Points.
To mark and to determine the control points, the researches landed
from the boat. The digital phototheodolite survey (normal and
with equal deviation of the optical axis of the camera) was done
from two bases fixed on the main altitudes.
The technology of mapping the coastline from the boat was used
to survey the western part ofthe island with the preliminary deter-
mination over all area under survey.
Thus digital phototheodolite survey done from the boat or from
the basic points, or with the use of GPS was applied to collect
data on the whole territory of the island. The collected data were
used in subsequent cameral photogrammetry work aiming at cre-
ating topographic map with the scale 1:1000 which will make a
basis for GIS.
The cameral work consisted in processing of the terrestrial pho-
tographs on photogrammetric station "Delta" [3].
