A collection of maps is called an atlas. Atlases can be thematic, focusing on specific topics such as geology, climate, or transportation, or they can be general, showing political, physical, or topographic features of different regions around the world. Atlases are valuable resources for education, exploration, and research, providing visual representations of spatial information. They can come in various formats, including printed books, digital versions, and online platforms. In addition, specialized atlases may serve specific audiences, such as travelers or scientists, making them essential tools for understanding geographical relationships and trends.
