Isoline Map

An Isoline map is a variation of a thematic map because like a thematic map it shows data of a specific subject for a specific purpose. Information is related through the use of lines that connect points of equal value. The map above demonstrates the amount of rainfall—from 250 mm annually to 11,000 mm annually that falls on the island of Maui, Hawaii; a place that I would not mind visiting.
