buffering parks

BUFFERS!

Since GIS is the theme for upcoming APHA conference, I am creating a map a day! Its quick, many map wont have detailed stuffs like legend and description, but depending on the time availability, I will be adding” layers to layers” 🙂 Here i created buffer (0.25 miles) around the parks in Washington DC. It beautifully explains how few regions do not have access to the park.
