What is an atlas?

An atlas is primarily defined as a book of maps or charts. This resource serves as a comprehensive visual reference, providing various geographical information that includes locations, boundaries, and topographical features. It can also feature thematic maps that focus on specific subjects such as climate, population, or political divisions. The organized collection of maps allows users to understand spatial relationships and the layout of regions, making it a crucial tool for students, researchers, and travelers.

While other options might pertain to different types of informational resources, they do not encompass the specific function and purpose of an atlas, which is focused on providing cartographic information.
