A collection of maps and charts is referred to as a "cartographic collection." Alternatively, it can also be called an "atlas" if it's specifically a bound collection of maps. Cartography, the art and science of map-making, plays a crucial role in navigating and understanding geography, providing valuable insights for various fields such as urban planning, environmental science, and history. These collections may include thematic maps, topographic maps, and oceanographic charts, among others, serving as essential tools for researchers, educators, and explorers alike.
