I have a database with 15 different pollutants measured at 40 stations. So it is a database of 15 columns and 40 rows. What I am trying to achieve is to create maps for each pollutant separately, that show the location of the 20 measurements, the severity of pollution at that particular spot (indicated with the size of an icon) and a buffer around each station with a certain distance from the center, depending on the severity of pollution measured at that particular station.
I am new to ArcGIS and I have now created the maps with graduated symbols, but somehow I cannot find a way to create buffers around the measurements.
Any help will be greatly appreciated!
