A new interactive map-based web application named Mapka was published by the Institute of the Czech National Corpus in 2020. It aims to serve linguists, as well as schools and the general public, and it features various functions described in this paper.
Mapka was designed as a supplement to the CNC spoken corpora, starting with the DIALEKT corpus (more to come in the future). Its main function is to display various types of territorial division (primarily in terms of dialect, but also administrative) and networks of localities associated with the corpus.
The main dialect regions are provided with overviews of their typical dialectal features and two samples of dialectal discourse - one slightly historical and one contemporary. The application offers the possibility of searching for municipalities, plotting the points on the map and creating a custom map.
The paper concludes with future prospects concerning an enhanced and improved version of the application.
