25. Isopleths


An isopleth map simplifies data with a continuous distribution, showing the data with a contour line connecting same ratios/amounts of some geographical or meteorological characteristic on a map; they are common for mapping elevation, precipitation, atmospheric pressure, etc.  In this map, isopleths were drawn around municipalities of equal levels of development in the Bicol River Basin.
