Module 4: Overlay Analysis

 

In this week's lab, I used ArcGIS tools to analyze and then create a map of suitable campsites within the De Soto National Forest in southern Mississippi. I overlayed buffer zones, specified for roads and waterways (rivers and lakes) to result in the polygons above. This criteria selection allows for the campsites to be a safe distance away from these features while still being accessible to them. Another criterion analyzed was that the possible campsite areas could not be located within conservation land. The legend in the lower left highlights the distinctions between the resulting areas. The sections are divided between areas as percent of total with yellow being the smallest section, then pink, and with navy blue equaling the largest section as a percent of total land. I chose these colors as I wanted to make the distinctions between the sizes. I applied the feedback from my graded assignments and worked to improve the legibility of my map. I ensured to use proper guidelines (I decided on 0.25in borders here). This lab provided me an opportunity to further use ArcGIS Help and Esri tools. I learned how to use the "Extent Indicator" tool within the Insert Tab for a seamless border around the location of the primary map within the inset. In this lab, I tried to create a more inviting map and I found the title(s) font to be a simple but standout font option. Overall, I really enjoyed this lab and I value the time I spent exploring and testing different strategies as I know I can apply them to future projects.
