This weeks assignment for module 6 had an objective of creating a isarithmic map of precipitation in the state of Washington. Isarithmic mapping is a common form of mapping used for presenting various types of smooth and continuous data using varying symbology. The map we produced in this module uses precipitation data derived using the Parameter-elevation Relationships on Independent Slopes Model (PRISM). PRISM contemplates a variety of factors which are interpolated to produce highly accurate climate data. The map also incorporated the creation of contour lines from the PRISM data. Hypsometric tinting was added in combination with contour lines to make a map with clear delineations that could easily be deciphered by a map reader. 

Data processing the lab itself involved using tools within the spatial analyst toolbox and classifying data to create easy to read and interpret divisions on the map. The PRISM process along with details on how the data was produced were included on the map.
