spatial concentration or focus, interregional migration, redistributive role of regions, Slovakia

In this paper an attempt is made to investigate the degree of spatial concentration or focus exhibited by the system of interregional migration flows in Slovakia during the 1981-2004 period. Adopting the coefficient of variation as an index of spatial focus, we first examine the spatial concentration in the entire system of interregional migration flows. The index is then employed to assess the spatial focusing of migration from and to each region. Finally, the simple classification method is used to evaluate the redistributive role that particular regions play in the national migration system.

commuting, interdistrict commuting, spatial components of commuting, district level, Slovakia

This study deals with selected spatial aspects of commuting to work at the level of individual districts. Commuting was assessed according to the number of out-commuters in all communes of a district, percentage of out-commuters of the total economically active population and from the point of view of individual components of commuting including commuting in the commune, commuting to other communes in the district, commuting to other districts in the same region, commuting to other district in other region and commuting abroad. These analyses led to classification of districts by importance of the individual components of commuting. Districts were classified into three basic groups: districts with a distinctly above-average share of out-commuters in the district, districts with an average percentage of out-commuters in and outside the district, and districts with a distinctly above-average share of out-commuters outside the district, while the districts in the first and third groups were further broken into three categories.

transition, spatial development, micro-regional tier, association of municipalities for spatial development, partnership at micro-regional level

The study deals with smallest spatial developing unit, the so called micro-regional tier. This tier had developed during the transition process. Institutionalism and operation of the organizations of micro-regions can be linked to three periods during the transition decade. The 1990s was the first period, known as the “early days”. In this period there was a diffuse atomized local municipality system with micro-regional co-operations mainly in the rural areas, which supported the villages with the aim of enhancing their lobbying capacity. During the second period these organizations operated as a bottom-up model and gained different financial resources for the common infrastructure development and started a way of micro-regional thinking. The third period started after the appearance of the 1996/21 Act (on physical planning and spatial development). It was a significant milestone for micro-regional co-operation, because this act defined the micro-regional level and declared micro-regional co-operation in the Spatial Development Association of Municipalities. The micro-regional tier can be named the tier of bottom-up and local will. In the rural areas, it meant a social innovation process, which is the result of this tier and is strengthened by the modified spatial development act in 2004.

geomorphology, GIS, mapping, geomorphological information system, geodatabase

An information system storing relevant geomorphological data and equipped with special analytical tools for geomorphological research can be termed a Geomorphological information system (GmIS). A GmIS should maintain a comprehensive geomorphological database, allow the user to generate specific geomorphological information and create (carto)graphic, statistical and other outputs. An attempt to create conceptual and logical models of a GmIS is presented here. The proposed GmIS is based on the GIS technology with layered database structure, divided into three main parts. Adopted layers imply existing geomorphologically relevant information from non-geomorphological sources. The basic geomorphological layers represent the most frequently used immanent geomorphological data: DEM and its derivates, documentation materials, elementary forms, basins, groups of genetic landforms, morphodynamic phenomena and geomorphic network. The special geomorphological layers are based on the above and are created by processing them. From many possibilities, two examples of geomorphological and morphostructural analysis are outlined. ESRI ArcGIS is suggested as the management system for geomorphological data.

landforms of mountain areas, tectonics, slope deformations, congelifraction, shallow seismic refraction, symmetric resistivity sounding, vertical electrical sounding

The aim of the presented study is to point out the possible use and interpretation of geophysical methods in the study of landforms of mountain areas. The main geophysical methods that can be used are represented by a group of geoelectric and seismic methods especially shallow seismic refraction, symmetric resistivity sounding and vertical electrical sounding. Results of the geophysical measurement and its geomorphological interpretation are presented on a problem-solving example of young tectonics, deep slope deformations and deep reach of Pleistocene congelifraction within the area of the Western Beskydy Mts and Hrubý Jeseník Mts (Czech Republic).
