This website is an interactive tool that allows you to view various criteria for different regions of the world simultaneously, along with being able to edit the map with markers and drawings. Though it is similar to ARCGIS software, this interactive map from National Geographic makes for a fun mapping experience. The criteria to view are grouped by categories including Physical Systems (land, water, climate), Human Systems (Populations & Culture, Political & Economic), and Environmental and society. The coolest thing about the map is being able to view multiple criteria at once, so for instance being able to see the human footprint of a region overlapping with volcanic eruptions to see if there is any correlation between the two. The drawing tools can be extremely useful, especially for measuring distances. If you select the ruler tool you can click between two points to measure the distance in km or miles. A variety of map modes are offered to view including terrain, topographic, satellite, streets, national geographic, and outline. All in all, this site is a great tool for geographers of all ages looking to explore different statistics and features of the world.
