Permanent renewal of measurements of phenomena occuring on Earth sufrace — the main task of geodesy and cartography — is the important element of geodynamic studies of the Arctic and Antarctic regions. Insitute of Geodesy and Cartography participates in the program of research led by Polish Academy of Sciences for over 10 years, using conventional geodetic methods, as well as new types of data, acquired from satellite observations and through remote sensing techniques. This activity is evidenced by setting-up astronomical main points close to Hornsund Station in 1958, as well as at Arctowski Station in 1976, where cyclic astronomical and satellite measurements were performed on these points. Geodynamic test site was organized in the Hornsund Region. As a result of these works numerous topographic and thematic maps were produced and many scientific publications were prepared by Institute specialists.
Cartography is the study and practice of making maps. Although originally defined for Earth, the term is also a perfect description of the aims of the VIPERS team, whose members include Polish astronomers.
On the basis of about 12500 depth measurements of which 6700 were taken from r/v Profesor Siedlecki, 1300 from r/v Polarstern and the remainder from British navigation charts, a bathymetric chart of the Bransfield Strait in the scale 1:500 000 has been prepared. Within the assumed boundaries the total area of the Bransfield Strait covers 65308.6 square kilometres, of which the Western Basin covers 23.5%, Central Basin — 47.3%, and Eastern Basin 29.2%. Capacity of the whole Bransfield Strait amounts to 38451 km3 . The average depth of the Bransfield Strait is 592 m.
Lexical knowledge sources are indispensable for research, education and general information. The transition of the reference works to the digital world has been a gradual one. This paper discusses the basic principles and structure of knowledge presentation, as well as user access and knowledge acquisition with specific consideration of contributions in German. The ideal reference works of the future should be interactive, optimally adapted to the user, reliable, current and quotable.
The article raises the issue of zoning of the central area of Zamosc based on downtown unrealized projects. It also explains the genesis of the formation of its range and the spatial layout, which affected the functioning of nineteenth-century fortress. As early as 1804. Entailer Stanisław Kostka Zamoyski planned to demolish the decaying fortifications and sell strip of land fortress for development. Change the situation on the political arena of Europe made Zamosc under Tsarist Russia became a fortress – a closed town, where civilian activity have been pushed to the back burner and separated from the historical center of strategic cordoned off the circuit. It was not until 24 years after the dissolution of the fortress, in 1880. returned to the development concept of post-fortress area in connection with the planned development of the city, but this met with opposition the military commission – the owner of the land. After regaining independence, the magistrate put forward ambitious building projects realization in the esplanade of the formerly fortress, which this time met with the resistance of the military commissions. As a result of the conversion of disputed land in the late 30’s the post-fortress area was possible to invest. An example was enacted in 1939, pioneering in many respects, zoning plan Zamosc by Władyslaw Wieczorkiewicza and Jan Zachwatowicz in which the authors called for implementation of the downtown on the basis of a linear array of bifocal between the old town (Stare Miasto) and the Nowa Osada suburb.
Research of semiotic aspects Lithuanian military air navigation charts was based on the semantic, graphic and information load analysis. The aim of semantic analysis was to determine how the conventional cartographical symbols, used in air navigation charts, correspond with carto-linguistic and carto-semiotic requirements. The analysis of all the markings was performed complex and collected by questionnaire were interviewed various respondents: pilots, cartographers and other chart users. The researches seek two aims: evaluate information and graphical load of military air navigation charts. Information load evaluated to calculate all objects and phenomenon, which was in 25 cm² of map. Charts analysis showed that in low flight charts (LFC) average information load are 4 – 5 times richer than in the operational maps. Map signs optimization on LFC has to be managed very carefully, choosing signs that can reduce the load of information and helps for the information transfer process. Graphical load of maps evaluated of aeronautical maps is not great (5 – 12%) and does not require reduction the information load and generalization of charts. Air navigation charts analysis pointed that not all air navigation sings correspond carto-semiotic requirements and must be improved. The authors suggested some new sings for military air navigation chart, which are simpler, equivalent to human psychophysical perception criteria, creates faster communication and less load on the chart.
