Summary from No. 1, 2006

MARSA, Jan: Local Improvement of Global Geoid Model on Foreign Territory. Vojensky geograficky obzor, 2006, no. 1, p. 4–7.
This paper deals with the principles of local improvement of NATO geoid model. It shows results reached not only in the Czech Republic, but mainly on foreign territory where technology is convenient and useful.

MARSA, Jan: Briefly about Technologies for Geodetic and Geographic Tasks in VGHMUr. Vojensky geograficky obzor, 2006, no. 1, p. 8–10.
The satellite GPS technology has belonged to the most often used surveying methods in the Military Geographic and Hydrometeorologic Office in Dobruska. These technologies are faster and more effective than past pre-satellite methods. Pre-satellite methods are more convenient for some applications. It’s the reason why so called intergrated geodesy seems to be perspective in the future. This paper deals with brief description of new geodetic devices and also some possible surveying technologies. Because one of the main tasks of MGHO’s Department of Geodesy is geodetic support of airfields, it’s mentioned also progressive Real Time Kinematic (RTK).

TICHY, Boris: Digital Geographic Information Working Group (DGIWG). Vojensky geograficky obzor, 2006, no. 1, p. 11–13.
Current activities of the international working group for geographic data standards DGIWG. Group functions, supported operational scenarios, identified projects, active projects.

JELINEK, Josef: The Impact of External Data on DMU 25 Database. Vojensky geograficky obzor, 2006, no. 1, p. 14–16.
The article deals with the impact of external data on the content, precision, and up-to-dateness of DMU 25 database(s). It lists briefly the most important external data sources and their content significant for database updating. Next follows a description how external data analyses influence their implementation to the database DMU 25. The last part shows problems with external data acquisition.

HUBACEK, Martin: The Impact of Terrain on Real Simulation Possibilities. Vojensky geograficky obzor, 2006, no. 1, p. 17–20.
The article deals with specific application of digital geographic databases produced by Geographic Service of Czech Armed Forces. The application builds terrain databases for constructive and virtual simulation systems currently used by Czech Armed Forces. The introduction briefly describes basic simulation principles. Next, steps for building terrain databases are analysed, using DMÚ 25 and DMR 2 databases. The last part shows expected development and requirements on input databases.

PIROH, Jaroslav – FILIP, Stanislav: E-government and Geospatial Data for State Government and Crisis Management. Vojensky geograficky obzor, 2006,no. 1, p. 21–25.
The article is dealing with the issues related to a modern society government. It is focused on the importance of information of the territory in the process of strategic planning of society development and its effective management. Special attention is paid to the issues concerning the crisis management and extraordinary importance of information of the territory in the process of crisis decision making. The final section of the contribution describes the current status of e-government development in Slovakia.

REPAL, Vladimir: Aspects Influencing Prediction of Ice Formation on Earth’s Surface. Vojensky geograficky obzor, 2006, no. 1, p. 26–28.
A large proportion of all road transport is affected by seasonal variation in the climate. In areas where the road surface temperature falls below 0 °C during winter, the effect for the road user can be dangerous driving conditions and long delays. In our country, much maintenance work is done by the national road administrations to improve winter-time road conditions and thereby keep up the traffic flow and decrease the accident rate. Forecasting the temperature of road surfaces is especially important in winter when icy conditions may occur. It is not straightforward, because of the wide variations in meteorological conditions which are found over short distances on the same night as well as variations in the thermal capacity and conductivity of different types of road and the road state.

SMID, Antonin: Current Studies of Geography and Meteorology at University of Defense in Brno. Vojensky geograficky obzor, 2006, no. 1, p. 29–33.
This paper deals with study program geodesy and cartography at former Military Academy in Brno, its development from 1990 to 2004 and attachment of geography (geodesy, cartography and photogrammetry) and meteorology courses at University of Defense. It describes current structure of Department of Military Geography and Meteorology and field of study structure.

BROUSEK, Ludek – LAZA, Libor: 55 Years of Military Geography in Dobruska. Vojensky geograficky obzor, 2006, no. 1. Appendix 1. 19 p.
Military mapping of our territory has a long tradition, with its beginnings reaching back to the 18th century. In the modern history of our country, after the founding of Czechoslovakia in 1918, military mapping of the republic had been undertaken by the Military Geographic Institute in Prague. After WWII the responsibility was transferred to Dobruška. In 2006 we commemorate the 55th anniversary of the military geography unit‘s arrival to this town on the foot of Eagle Mountains. 55 years that have been forever inscribed into the history of the mapping of our country; 55 years of technical development, installation of new devices and technologies, solving tasks of fundamental research and geographic defense of the state.

JURKINA, Maria Ivanovna – PICK, Miloš: Numerical Computations in World Geodetic System 1984 (WGS 84). Vojenský geografický obzor, 2006, no. 1. Appendix 2. 15 p.
The presented paper deals with the numerical calculations in geodetic systems of such a type as WGS84. As a concrete case the numerical values of the basic parameters of system WGS84 were used. The following analysis was carried out for the chosen point P (φ = 50°, λ = 15°, H = 10 000 m).
