An isoline is a line on a map or chart that connects points of equal value. These values can represent various measurements, such as temperature, elevation, or pressure. Isolines help visualize data, making it easier to understand patterns and trends across a geographic area. Common types of isolines include contour lines for elevation and isotherms for temperature. Isolines are widely used in fields like meteorology, geography, and environmental science. By analyzing isolines, scientists and researchers can predict weather patterns, assess landforms, and study climate changes. This visual representation of data enhances comprehension and aids in decision-making processes.
