Abstract
The article presents the preparation, development and implementation of interactive maps, which are one of the outputs of the Historical Sources of the Giant Mountains project. Their aim was to present completely newly collected statistical data and as yet unused maps in digital form in a form that would be available to the widest range of users and at the same time bring a sufficiently deep insight for professional researchers.
The result is two freely available maps documenting the development of the Giant Mountains region during the 20th century, the first focusing on changes in the structure of the population and the second on changes in the structure of the economy and transport infrastructure of the region. Both maps allow for comparative visualization of different types of statistical data relative to each other and at the same time diachronous comparison of the relevant development across chronologically organized time layers, representing the logical periodization of the history of the region.
The third map then provides users with information on the location and species distribution of various types of sources and sources to study the history of the Giant Mountains.
