Module 6 - Isarithmic Mapping

This module introduced isarithmic mapping using the average precipitation of the state of Washington over a 30 year period from 1981 - 2010. Isarithmic maps are used to show smooth, continuous phenomena across an area using varying symbology methods. The data was prepared using the PRISM (Parameter-elevation Relationships on Independent Slopes Model) interpolation method. Hypsometric tinting and contours were used to show the varying elevation across the state. I discovered I enjoyed working with this type of mapping more than any others we have created so far.
