The Atlas of Czech Dialects - Nominative Singular Feminine is the result of an interdisciplinary collaboration between experts from the Dialectology Department of the Institute of Czech Language of the Czech Academy of Sciences and experts from the Department of Geoinformatics of the Faculty of Science of Palacký University in Olomouc. The Atlas presents not only the dialectal phenomena that are declining and disappearing, but also the phenomena that are still alive. The main analytical dialect maps show the morphological differences in the territory of the Czech national language. The accompanying maps of spelling variations illustrate the overall territorial picture of the word form under study. In addition to the dialect maps and brief expert dialectological comments, the atlas contains texts describing the realities of former rural life, farming methods and customs, infographics, links to audiorecords and illustrative images created by artificial intelligence tools. The expert explanations are complemented by rich dialectal material, while the popular format of the texts ensures accessibility to a wide range of people interested in our dialect. Data from the Questionnaire for Research on Czech Dialects, processed into thematic maps, are brought to life by photographs taken by dialectologists half a century ago during field research.
