Week 4: Vector Analysis

 

This weeks map is of De Soto Forest in Mississippi. The theme for this week was vector analysis. I utilized the buffer tool to create a 300 m buffer around the roads layer. Similarly I made a variable distance buffer for the water feature that had its distances set for 150 m around lakes and 500 m around rivers. In order to make the distances for the buffers I added two short fields to the attribute tables of the respective layers that corresponded to the distances. Next, I performed a union after creating another round of short fields that utilized Boolean Logic (1 is true and 0 is false). after creating the union, I selected and then exported as a new layer all buffers that where within both the original water and road buffers. After this I utilized the Erase tool in order to remove from the data all features that intersected the prescribed conservation layer. Then I created my map/

My map contains a boundary of the De Soto National Forest that I obtained from the USFS. Additionally The water and roads layers are there and came from FGDL. I also have the buffer indicating where the largest camping grounds are located, the lighted colors indicate smaller areas, wheras the dark red indicates the larger areas. I created an inset map highlighting the location of the national forest in relation to the rest of Mississippi. Additionally, I have created a legend that explains the various symbologies.
