Module 7: Data Search


This week's assignment was to apply the knowledge we've gained about searching for and locating GIS data online and projecting the data correctly.  Ultimately we were responsible for making a map about a specific county in Florida; my county was Columbia.  We were further required to map two county-specific environmental features of our choice; I chose invasive plants and Strategic Habitat Conservation Areas.  My maps focus on two large cities (Lake City and Columbia, respectively) in Columbia County, FL.

The first map (top) displays invasive plants by species in a particular public land unit, "Alligator Lake", located in Lake City, FL.  I chose to use two inset maps - one of Florida and one of Columbia County - with additional in-map labels to help the viewer better orient themselves with the location of interest.  The second map (bottom) is very similar in layout, but displays Strategic Habitat Conservation Areas near Columbia, FL of varying priority levels.  The Digital Elevation Map used in this map allows the viewer to imagine the topography - slope, aspect, etc. - at these conservation areas.  

Overall, I am satisfied with the presentation and completeness of these two maps.  I felt the ability for me to choose what to emphasize in my maps allowed me to play around with different ArcMap features I was unfamiliar with.
