Current soil and surface data are not detailed enough to obtain accurate analyses of cross-country movement. The reason for the research presented in this article was the absence of a methodology for the synthetic assessment of the influence of the terrain surface on the movement of military vehicles. The study is based on analyses of data and information sources of soils and surface conditions primarily with the aim to determine their reliability, availability and precision when used for analyses of terrain traversability by off-road vehicles. The key method to achieve the set objective is the employment of tractive charts of military vehicles and utilized coefficients, the coefficient of rolling resistance and the coefficient of adhesion. Input data and information is tested with a comparative method of cross-country movement analyses. Conversion of soil and surface types to tractive chart coefficients is currently not optimal. For the most part, evaluation of soil type is very inaccurate with a wide range of possible values. Results of the analysis propose developing a methodology of evaluating surface and soils for vehicle traversability.
The article studied databases of vegetation created from remote sensors, outcome of analyses of Cross-Country Movement in forests, and quality of utilized data. The aim was to combine various databases of forests and get statistics of best data by using different methods of evaluation. Passability in forests is mainly conducted with analysis of driving between trees. The most suitable datasets in the Czech Republic are Forest Economic Plan and Digital Elevation Model 5th generation combined with Digital Surface Model 1st generation. Accuracy and usability of databases were compared with digital model of surface created from orthophoto images. Processing of data is the most important part that influences quality of statistical and map results. Studied characteristics of input databases and applied methods also have considerable influence on results of analysis of forest passability. The outcome substantially varies for personnel armored vehicles and wheeled vehicles mostly due to their movement capabilities.
Smart defence in NATO may in its very nature represent not only automated remote solutions for battle activities, but harmonized and efficient system of geospatial support of deployed units as well. The objective of this study is to uncover the essence of allied geospatial support mechanism, determine critical spots and propose appropriate system enhancements. Wealth of experience of members of the Armed forces of the Czech Republic was utilized to summarize the state of geospatial support in NATO. It is preferentially experience from foreign operations ISAF and KFOR, cooperation with NATO Headquarters SHAPE and from participation in Multinational Geospatial Support Group. Presented proposals for improvements of geospatial support might have significant impact on intelligence service and military units themselves. Highlights for public administration, management and planning: • Multinational Geospatial Support Group will become a single complex executive component of NATO geospatial support for foreign operations. • Financial and capacity means for geospatial support must be centralized directly within NATO structure to reach maximum efficiency. • Production of standardized-only scale set maps covering territory of NATO and areas of interest is to be obligatorily for all member nations. • Access to the web service CoreGIS should be granted for all NATO nations at a national level.
Článek pojednává o možnosti použití globálních navigačních družicových systémů Galileo a BeiDou v armádě České republiky, analyzuje jejich přednosti, slabiny a zásadní přínosy pro armádu. Studie využívá poznatků a zkušeností Geografické služby AČR při porovnání s již zavedenými systémy GPS a GLONASS. Evropský projekt Galileo přináší především nezávislost na GPS a přímou vazbu ČR. Čínský BeiDou poskytuje samostatnou alternativu, ovšem s omezeným přístupem. Oba systémy mohou v kombinaci s multikonstelačními přijímači výborně doplňovat aktuální strukturu, celkově zpřesňovat polohu a snížit zranitelnost vůči rušení a klamání. AČR může využít výhody systémů pomocí modernizace zařízení a účastí na rozvojových projektech globální navigace.
The article analyses activities of geographical support in missions abroad. The proposals for adjustment of processes and equipment during a preparation phase of perspective deployment of mobile geographic support unit were created on a basis of author's knowledge and experience, studies of documents and a discussion of participants in missions. The ISAF mission (currently Resolute Support mission) represents a model on which a future form of geographic support of national contingents in missions abroad is being developed. The brought up results represent a recommendation for further development of geospatial support of AČR in missions. The main conclusion is defining a need of position for a geographer within a mid-sized contingent and at a same time making use of a new mobile geographic set GeMoZ-C, which already complies with a majority of mentioned remarks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
