Landscape photography in the research of landscape change
Skokanová, H.; Halas, Petr; Koutecký, T.; Kallabová, Eva; Havlíček, M.; Slach, T.
2022 - English
The paper presents partial results of “entering” landscape photography, which can be considered as a complementary method for the research of landscape changes. Unlike the usual assessment of landscape changes using cartographic and other archival sources, old landscape photographs can contribute to the deeper knowledge of the local specifics of the examined places or supplement the conventional procedures. Thanks to the ongoing project, supported by the Technology Agency of the Czech Republic (TL02000222), we documented changes in photographic shots of various landscapes in the 20th century. We also added information about environment, vegetation, and geography and photo documentation of the details of the researched shot. This creates a comprehensive output for each old landscape photograph. Such processed photographs have been presented at exhibitions in museums and galleries. Furthermore, they will be available to municipalities and public at a web page created as a tool to support public recreation. Here we present some examples from the Bohemian-Moravian Highlands. They show four types of landscape changes: 1) afforestation and overgrowth bywoody vegetation, 2) changes in the agricultural landscape, 3) loss of the grazing landscape, and 4) changes related to watercourses.\n

Polycentric urban forms: The relevance of scale for metropolitan and city planning
Malý, Jiří; Krejčí, Tomáš
2021 - English
The paper deals with the importance of scale in metropolitan and urban planning, in connection with the promoted and often applied concept of polycentric development. Although the normative conceptualization of polycentricity to some extent reflects the multi-scalar dimension, the operationalization of the concept encounters a number of limitations and fuzzy meanings that result from different scales of analysis and interpretation. Using the Czech context of planning practice, the negligence of the importance of overlapping geographical scales and limits of binding spatial planning materials is documented. The dependence of polycentricity on the scale has consequences both for the analytical evaluation of the spatial situation of the settlement system and for the subsequent interpretation of the results and the setting of further development strategies.\n

RTIN-based strategies for local mesh refinement
Kolcun, Alexej; Sysala, Stanislav
2021 - English
Longest-edge bisection algorithms are often used for local mesh refinements within the finite element method in 2D. In this paper, we discuss and describe their conforming variant. A particular attention is devoted to the so-called Right-Triangulated Irregular Network (RTIN) based on isosceles right triangles and its tranformation to more general domains. We suggest to combine RTIN with a balanced quadrant tree (QuadTree) decomposition. This combination does not produce hanging nodes within the mesh refinements and could be extended to tetrahedral meshes in 3D.

Resuscitation of landscape painting by research of landscape changes
Havlíček, M.; Slach, T.; Skokanová, H.; Halas, Petr; Kallabová, Eva; Koutecký, T.; Šebesta, J.
2021 - English
An analysis of selected landscape paintings shows that only a third of them are located directly on a hiking trail, bike path or nature trail. In the case of other landscape paintings, it is possible to make other, hitherto neglected parts of the territory more attractive to tourists by locating the places of the painter's shots, which may lead to their desired deconcentration from the places that are frequently visited by tourists.

New opportunities for geotourism development at geoarcheological site Holedná Hill (Brno, Czech Republic)
Kubalíková, Lucie; Kirchner, Karel; Kuda, František
2021 - English
Special Interest Tourism is often seen as a form of ‘alternative’, ‘ethical’ or ‘environmentally responsible’ tourism and it occurs when the tourists’ motivation and decision-making are primarily determined by a particular special interest with a focus either on activities and/or destinations and settings and search for novel experiences (Novotná et al. 2019). \nOne of the types of sites are called geocultural sites (Reynard and Giusti 2018). Geoarcheological sites can be considered a type of geocultural sites and can be defined as sites where geological aspects are accompanied and closely related to archaeological issues. \nThe Holedná Hill (Brno, Czech Republic) can be considered an example of such geoarcheological site. It is important from the Earth-science point of view and it includes specific archaeological issues that are closely related to the geodiversity. This paper briefly sums the natural and cultural values of Holedná Hill and based on the geomorphosite assessment and SWOT analysis.\n

Anthropogenic relief transformations - their knowledge and evaluation with regard to the uniqueness and cultural identity of regions
Kirchner, Karel; Kubalíková, Lucie; Kuda, František; Havlíček, M.
2020 - English
Within the development of new regional geography, the role of human geographic research in the study of regions is emphasized. Regional uniqueness, a consciousness of belonging to a particular However, physical geography disciplines, e.g. geomorphology, can also contribute to the knowledge of these aspects with regard to the definition of regions. Currently, within the framework of geomorphology, attention is paid to the diversity of anthropogenic landforms. The knowledge and evaluation of these anthropogenic landforms, which are an important part of the historical elements of the landscape and are also referred to as cultural artefacts of the landscape, enables to supplement the cultural-historical values of the region and to specify the cultural identity of the region. On the example of sites - Staré Hradisko and Hostýn - we will present the specifics of secondary geodiversity with respect to the cultural identity of the sites.

Geological paths – their use for the regional geography teaching
Kubalíková, Lucie; Drápela, E.; Bajer, A.; Zapletalová, D.; Balková, M.; Zágoršek, K.; Kirchner, Karel; Kuda, František; Roštínský, Pavel
2020 - English
Geological paths (geopaths, geotrails) represent a type of educational paths that connect sites, which are interesting from the Earth-sciences point of view. These sites (e.g. outcrops, old quarries, historical buildings built of local stone or viewpoints) often represent the links between geodiversity and other phenomena within a region (which is in accordance with a holistic approach to geotourism). Thus, they can give complex information not only about the abiotic nature but also about biodiversity, history or culture of the region, usually through narrative. Suitable interpretation of geodiversity and its relationships to the biodiversity and cultural heritage allows to identify regional specifics, it helps to find the mutual connections between particular phenomena within the region and it supports the holistic perception of a given region. The contribution presents an example from the Brno city where the urban geopath can be used for teaching regional geography of Brno and its surroundings.

Developing urban geotourism in Brno (Czech Republic)
Kubalíková, Lucie; Kirchner, Karel; Bajer, A.; Balková, M.; Kuda, František
2020 - English
The term “urban geotourism” is defined as tourism based on the places within the city boundary (both in the form of built heritage - monuments, buildings, statues - and rock outcrops) that is related to geological concepts and features. As a first step for the development of urban geotourism it is necessary to identify and inventory the geotourist resources, which should take into account both natural (geological, geomorphological, hydrological or palaeontological, and ecological aspects related to geodiversity), and cultural aspects related to geodiversity (e.g. monuments, building stone, geo-toponyms, anthropogenic landforms). Based on the classification of geotourist sites, selected examples from Brno (Czech Republic) are given, supplemented by geotourist and geo-educational activities. In the conclusion, the advantages of urban geotourism are summarized and its importance for the protection of abiotic nature and sustainable management of valuable sites is suggested.\n\n
