What is a isoline map?

An isoline map is a type of map that shows lines connecting points of equal value, such as elevation, temperature, or distance. These lines are called isolines and help to visualize and understand patterns and variations in the data being represented.

Isoline maps are commonly used in meteorology, geography, and geology to represent phenomena like weather patterns, topography, and seismic activity. By interpreting the spacing and arrangement of isolines on a map, viewers can identify trends, gradients, and concentrations of the data being represented.

Isoline maps may include labels indicating the value that each line represents, as well as a legend to help users interpret the map. They are useful for identifying regions of high or low values, determining boundaries and patterns, and making comparisons between different areas.

Overall, isoline maps are a valuable tool for visually representing spatial data and are commonly used in a variety of scientific disciplines to convey complex information in a clear and concise manner.
