The Prime Meridian is the zero-degree longitude line from which all other longitudes are measured, serving as a global reference point for time and navigation. It passes through the Royal Observatory in Greenwich, England, and is crucial for the system of Coordinated Universal Time (UTC).
Topographical maps are a detailed representation of the three-dimensional features of a terrain on a two-dimensional surface, noting elevations and landforms through contour lines. These maps are essential tools in geography, environmental studies, and outdoor activities due to their ability to precisely depict the physical layout of a landscape, providing crucial details such as elevation changes and terrain types.
Mapping involves representing geographical features visually. Key elements include landmarks, routes, and terrain. This concept provides the foundation for creating accurate and useful maps.
