Isoline maps use line symbols to portray a continuous distribution such as temperature or elevation. Isolines are lines that connect points of equal numeric value. Many metorologist use Isoline maps to quickly show temperature differences on maps with the hottest areas normally represented by the color red, the the warm areas by the color yellow, and the cold areas by the color blue. This map above shows the surface dew point temperature in the United States at a particular point in time. High dew point temperatures suggest areas that will consist of fog, the lower dew point ares suggest dry air which could lead to fire hazards for certain areas. The amount of water vapor that has consumed an area are represented , in this map, by the color red.
