The main goal of this diploma thesis was to perform a cartographic synthesis of selected topics from the mapping of spoken non-literary language in the Czech Language Atlas. Next goal is the creation of map outputs from the results of this process and its statistical evaluation.
In the theoretical part of the work, main focus was on the study of dialect research as such, then there was a search of domestic and foreign language atlases and a detailed study of the Czech language atlas. Subsequently, a selection of topics from the Czech Language Atlas was made, which was intended for entry into the cartographic synthesis itself. Three criteria were created, according to which 16 maps showing the phenomenon of shortening were selected.
In the practical part, the first step was the georeferencing of selected maps and vectorization of their content into a format that can be processed in a GIS environment. The result was point, line and area elements showing individual phenomena contained in maps from Czech Language Atlas, a symbol design draft for vectorized layers was created in ArcGIS Pro and saved in STYLX format. Main goal of the created draft was to increase the intelligibility of the resulting maps. These maps were called analytical dialect maps, which were compiled in the next step. Result of this process was a set of 16 maps showing phonetic variants with the use of the created graphical symbol draft.
The next phase was to perform typization on analytical dialect maps. After consultation with a dialectologist, 12 analytical dialect maps entered this process. Typization was performed on the basis of overlay analysis. This created a layer containing unique sequences of long or short sounds. After generalization, which removed parts smaller than 150 km2, six types of vocal shortening were assembled. A typological map was then compiled from the resulting typology, which was the entry into the process of regionalization, for which the method of visual evaluation was used. The result was the regionalization containing 13 types of vocal shortening regions, from which a map of regionalization was subsequently compiled.
Then a statistical evaluation of the created typology and regionalization was performed. The share of population representation for each type and region was evaluated, as well as the territorial distribution of individual types and regions within the territory of the Czech Republic. The share of the representation of types and regions of vocal shortening within the Czech dialect areas was also calculated.
The last part was to compile an atlas entitled "Atlas of the Czech Language Dialect: Shortening Vocals," which included analytical and synthetic dialect maps along with its statistical evaluation.
The main goal of this diploma thesis was accomplisht by fulfilling all partial goals. The derived results and procedures can be used in future related research as an example for processing spatial dialectological maps.
