In this weeks Lesson geospatial analysis tools were discussed, and we took a deeper dive into one of the most common tools: Buffering. In this forum, go to the Esri ArcGIS help site. Take a look at the commonly used analytic tools. Pick one and discuss its use. What does it do? How is it used? Do you see a use for the tool in our Presidential Inaugural project? Would you use it?
