The map above shows a section of Marion County, Florida that I am analyzing for areas considered food deserts. Food deserts are classified as areas where individuals do not have immediate access to healthy foods. This map was created using open source software such as QGIS, ColorBrewer, MapBox and then uploaded onto the web using Leaflet.
I obtained the data for this analysis from the Marion County Open Data Portal. I also obtained population information from Factfinder.census.gov. The population table was then joined to the Marion County census tracts shapefile. The Grocery Stores layer was produced by creating my study area file in ArcGIS, converting it to a KML file and uploading it into Google Earth. From here I searched for grocery stores within the area and created a point layer. I then took my Grocery Stores KML file and converted it into a Shapefile. I found using Google Earth to create my Grocery Stores file to be helpful because it is easy to search for businesses and the street view allows you to ground truth.
Below is a link to my web map, give it a look!
