A cartographer is a professional who creates maps. They use various tools and technologies to gather data about the Earth's surface, including geographic features, roads, and political boundaries. Cartographers often work with geographic information systems (GIS) to analyze and visualize spatial information, making it easier to understand complex data. In addition to traditional paper maps, cartographers also produce digital maps for websites and applications. Their work is essential for navigation, urban planning, and environmental studies. By accurately representing locations and features, cartographers help people make informed decisions about travel, land use, and resource management.
