Summary of No. 1/2005

JANUS, Petr: World Geodetic System 1984 (WGS 84). Vojenský geografický obzor, 2005, no. 1, p. 4 –9.

Based on STANAG 2711, World Geodetic System 1984 (WGS 84) is implemented into the Czech Armed Forces as of 1 January 2006. At the same moment, utilization of the current 1942/83 datum is abolished. WGS 84 positioning may be done in different ways. For reasons of uniqueness and simplicity, MGRS (Military Grid Reference System) coordinates are mostly used in operations.

JANUS, Petr: Building of World Geodetic System 1984 (WGS 84) in the CzechRepublic. Vojenský geografický obzor, 2005, no. 1, p. 10 –11.

Geodetic foundations for WGS 84 (G873) datum were established on the Czech Republic territory in 1992 and improved in 1999. On the basis of identical point coordinates, transformation procedures have been determined and all horizontal control points transformed from 1942/83 datum to WGS 84 (G873) datum.

SKLADOWSKI, Jiří: WGS 84 Implementation into Geodesy Practice. Vojenský geografický obzor, 2005, no. 1, p. 12–13.

WGS84 implementation into geodesy practice has been caused by GPS apparatus utilization at the beginning of 1990s. Till then 1942/83 datum had only been used. Expansion of GPS equipment and joining NATO has raised question of collaboration with other NATO nations, i.e. need of WGS84 utilization within Czech Armed Forces.

MARŠA, Jan: Implementation of Quasigeoid Local Model into Software for GPS Processing. Vojenský geografický obzor, 2005, no. 1, p. 14 –18.

This paper deals with the convenience of local model implementation into Trimble software for GPS processing. The article describes used model transfer into required format. Moreover, the precision of models is verified and practical application in geographic service is mentioned.

TICHÝ, Boris: Digital Products of Military Geographic and Hydrometeorologic Offi ce – Standards and WGS 84. Vojenský geografický obzor, 2005, no. 1, p. 19 –24.

Brief overview of the approach to geographic data standards in preceding period of geographic data development and production. A list of current main geographic datasets produced in VGHMÚř with respect to standardization of both content and formal, in relation to national and international connections of present Czech Armed forces.

WILDMANN, Radek: Military Cartographic Production in Geographic Service of the Czech Armed Forces. Vojenský geografický obzor, 2005, no. 1, p. 25 –34.

Military cartographic production in Geographic Service of the Czech Armed Forces has very long tradition. The first countrywide topographic mapping at scale 1 : 25 000 was carried out after 1953. Map production is based on the Law 200/1994 on surveying, on the Order of Chief of General Staff of ACR N°34/1997 and on the NATO Geographic Policy. New standardised maps are produced using digital production system in accordance with NATO STANAGs. The main data source for maps production technology is vector database Digital Feature Model 1 : 25 000 (DMÚ25).

MORAVEC, Zdeněk – VÍTEK, Karel: The Exchange of Reserves of Geographical Products in the Czech Armed Forces. Vojenský geografický obzor, 2005, no. 1, p. 35 –37.

The validity of the grid system S-42/83 will expire on 31st December 2005. The geographical products, which are made in accordance with the relevant standard of NATO in reference system WGS 84, will be fully implemented into use from 1st January 2006. The article briefly describes the procedure of reserves exchange. Parts of the article are lists of valid geographical products together with products which will be discarded.

LAŽA, Libor: Geodetic, Geophysical, and Hydrometeorologic Tasks of Special Monitoring and Metrology Workplace POLOM. Vojenský geografický obzor, 2005, no. 1, p. 38– 43.

Special monitoring and metrology workplace is a detached facility of Military Geographic and Hydrometeorologic Office. It provides Czech Armed Forces units and Integrated Command System with geophysical and hydrometeorological information. The facility cooperates with Geophysical Institute of Czech Academy of Sciences, Research Institute of Geodesy and Cadastre, and Czech Hydrometeorologic Institute.
