The authors focused on the analysis of landscape changes that took place in the central part of the Ostrava-Karviná Mining District (northeastern part of the Czech Republic) from the first half of the 19th century to the beginning of the 21st century. Land cover and land cover changes were mapped in detail in the observed cadastral areas (Lazy near Orlová, Karviná-Doly, and Darkov). With regard to the existing data sources, the years 1836, 1947, and 2003 were selected as significant time milestones. Land cover was derived from cadastral maps (year 1836) and aerial photos (years 1947 and 2003). Land cover interpretation was carried out at a scale of 1:5,000. A 1:25,000 scale map shows land cover of studied cadastral territories in each monitored year. Land cover changes are presented in three 1:30,000 scale thematic maps: (1) Number of land cover changes, (2) Same-type land cover preservation, and (3) Landscape processes. Land cover change maps are complemented with tables and graphs. The tables contain numerical data on total areas of change (or identical land cover) and their percentage representation in the total area of the studied territory. Area comparisons are given in the graphs.
