Oregon Maps (from Part II)
Figures 1 and 2 (below) are shaded relief maps of Oregon with contour lines. It was difficult to determine an acceptable contour interval (for such a scale), as none of the results were appealing. A contour interval of 100 m was too cluttered and an interval of 1000 m was too general. A 500 m interval was chosen as it showed elevation changes without cluttering the map. The hillshade specifications are indicated below.

Oregon Maps (from Part III)
Figures 3 and 4 contain interpolated precipitation data, as well as control point locations for Oregon. Both maps were generated using IDW and use precipitation contours at 1 inch intervals. Bold contour lines were symbolized at 5 inch intervals. Figures 3 and 4 were generated with the same specifications, the only difference between the two is hillshade is included in Figure 3. The specifications used for the figures are indicated below
