Isoline maps


http://legacy.sfei.org/ecoatlas/GIS/MapInterpretation/MapsandScales.html
Isoline Maps show patterns that when displayed on a 2-dimensional map display a 3-dimensional (usually overhead view) of environmental surfaces. Dimension in the map above was accomplished by connecting points of equal value (Isolines) to give the reader a better understanding of where elemental change takes place.  This interpolation differentiates higher value from lower value and measures several elements of the natural environment such as elevation, wind speed, and rainfall to name a few.
