Summary

The aim of the work was to find out the possibilities of migration visualization in interactive web maps. The work was divided into three parts. The first part of the work consisted of the study of the theory and of analysing the analog and digital migration maps. Several aspects were analyzed in the maps, the most important were the cartographic method, as well as the means of expression and the technology used with a possible JavaScript library. All analyzed maps were putted into gallerie on web of the bachelor work and as Annex No.1. This was followed by a survey of technological possibilities for the creation of interactive web maps, from which 6 products were selected for testing and subsequently evaluating: Leaflet, MapBox, ArcGIS Online, Here Studio, PowerBI and Flowmap.Blue.
Another part of the work was testing, which was done by creating migration maps. A total of 9 different interactive map outputs were created using the line method and cartogram method. The last part of the work consists of the evaluation of individual solutions based on the author's experience supplemented by available information of products.
From the results of the theoretical part of the work it was found that the most used cartographic method for recording migration is the line method, which should be supplemented by a basis in the form of migration balance (cartogram method). This finding was reflected in the creation of map outputs that demonstrate the available migration visualization options for beginning programmers as well as experienced GIS workers. The procedure of creating the maps is described in the text of the work and will be an honor for the author, if it serves at least once as a guide for the future creator. The source code of maps and websites is freely available, so the elements can be used for future creation. The results of this section show a certain difference between proprietary and free-source solutions. While free-source solutions provide analytical capabilities (Turf.js), dynamic and interactive functions, and many general elements, proprietary solutions focus mainly on analytical elements, and the dynamics or interactivity of maps is thus lagging behind. In the subsequent evaluation, the user can go through the individual solutions, find out their advantages and disadvantages, and thus reasonably choose the most suitable according to their preferences.
UA website was also made as a part of the bachelor work, on which all created maps, galleries of analyzed maps with a description of selected cartographic methods, and the evaluated technologies are accessible. Furthermore, you can download the full text of the thesis in PDF format and a poster in A2 format, which was also created as an appendix to the thesis.
