GIS 4006 - Module 8 - Isarithmic Mapping

For this weeks lab, module 8, we were tasked with creating a map that utilizes continuous tone and hypsometric tinting in order to display precipitation data for the state of Washington over a period of 30 years. 
A continuous tone symbology is one that is classless and represents individual points as colors or tones corresponding to values. This symbology is implemented into the Washington Precipitation map as square inches of rainfall with orange tones indicating low values and blue tones values indicating high values.
Hypsometric tinting is a symbology method for enhancing elevation. By assigning colors or tones to contour lines or lines of equal elevation relief can be visualized easier. Colors chosen are typically tones or shades for ground cover found at that given elevation. 
The PRISM group at Oregon State University compiled this point based data set for the entirety of Washington state from 1981 - 2010. The attached map was created utilizing arcgis pro and includes all essential map elements while taking into account cartographic design principles.
