This weeks lab assignment centered around the the elements of Isarithmic maps. The goal was to create a continuous color fill symbol, hypsometric tinting, and contour maps with an existing PRISM precipitation data raster data of Washington State.
Completing the lab assignment was easy and fairly straight forward by first creating a map with continuous colors then adding a hypometric tinting or layer tenting showing the differences in relief. Basically, it accentuated the changes in elevation enhancing the users ability to see concentration of perceptional when encouraging changes in elevation.
The next step in the lab evolved reclassifying the raster from floating point values ot integer values. Using the raster of integer values it was necessary to create contour lines using the same manual breaks, shown in the final map below.
