Concept:Maps use internationally agreed symbols to represent real-world features, making them understandable to people of any language.
Explanation:It is impossible to draw actual shapes of buildings, roads, bridges, or trees on a map. So, mapmakers use letters, shades, colors, pictures, and lines to show these features. These standard symbols are called conventional symbols. They save space and make maps easy to draw and read. Because there is an international agreement on their use, any person, even without knowing the local language, can understand the map. For example, a blue line always represents a river, and a black dot with a label may indicate a city. Other map components like sketches, alphabets, or thematic maps are not universal. A sketch is a rough drawing based on memory, not to scale. Alphabets are used only for special labels (e.g., PO for Post Office). Thematic maps focus on specific data like rainfall or roads. Only conventional symbols provide a universal language that works across all regions and languages.
