Maps focus on a few selected characteristics of the region or give an overview of the region under consideration. Atlases often contain social, religious, economic, and geopolitical information for a specific region. Maps and atlases are the primary tools for spatial analysis. They may project physical, biological, or cultural features of the region or depict a correlation between several features of the region. Maps are made up of several components—symbols, title, legend, direction, map scale, source, and insets.
