The map below was created using selection and overlay tools to create a layer that expressed suitable campsite locations in the De Soto National Forest in Perry County, Mississippi.  The criteria used to determine these areas were: within 500 meters of a river or within 150 meters of a lake, and within 300 meters of a road.  Once these parameters were set and associated in a new layer, I removed any of these areas that overlapped with designated conservation areas.  The final layer was then split into 4 groups based on area in hectares.  I made a progressive color scale base on 200 hectare increments with larger areas being darker as those were preferred. The final map shows these areas along with the road and water layers for reference.  I made my scale bar in kilometers because the areas are in hectares and the map is based in meters.  The inset map shows an expanded view of Mississippi for reference.
