Cartographers are professionals who create maps, which are visual representations of geographical areas. They use various tools and technologies, including GIS (Geographic Information Systems), to gather and analyze data about the Earth's surface. Their work helps people understand locations, distances, and the relationships between different places. In addition to traditional paper maps, cartographers also produce digital maps for use in applications like GPS navigation and online mapping services. They must consider factors such as scale, symbols, and color to effectively communicate information. Their skills are essential for urban planning, environmental studies, and travel.
