Descriptions Figure 1: Contained within figure one, is a map which symbolizes each individual stand of trees based on their total amount of coverage. The map contains both the Brown Tract Boundary, and the Stands shapefile. Using Arcmap’s natural breaks classification as an initial starting point, I manually classified the breaks to a round number. Once separated into classes based on their acreage, I used a simple sequential color palette to better visualize the different classes. The use of color hue improves the overall effectiveness of the map, by allowing the map reader to quickly determine which stands have the largest area; those stand which have the dark green hue. Figure 2: Figure two provides recreationists some features of interest in the area of the Brown Tract. While these features are rather basic, they are essential for accessing the region and utilizing the Brown Tract to its fullest potential. I first use the digital elevation model as a baselayer, which is given a hue based on the elevations it contains. I this case, a simple green for low areas, and a light tan for higher. Two layers are then produced from the DEM, a hill shade and a curvature layer. Both layers are semi transparent to allow the base elevation color through, giving us a hypsometric tint. Then the following was overlaid on…show more content…
The map uses aerial imagery collected in 2007, as part of the statewide DCNR PAMAP Program. A polygon representative of the extent of Lake Perez was created using the heads up method of digitizing. Next the geometry of the completed lake polygon was calculated, covering approximately 71.20 acres. One method used to increase the effectiveness of the map was the use of transparence. Both the lake and the information boxes have a level of transparence, allowing the underlying imagery to still be visible to a certain
