Cartography is the study and practice of making maps. It is concerned with the representation of the Earth's surface and its features on a flat surface. Cartographers use a variety of techniques to create maps, including surveying, remote sensing, and computer-aided design.
The dividing up of the earth into smaller sections is not a concern of cartography. This is because cartographers are focused on creating accurate and useful representations of the Earth's surface, rather than on dividing it up into smaller units.
