Thanks Jason. If I find time, I will play around with QGIS to see if I can get it to create the buffers and export them to itree canopy.

For a malaria study, I want to use iTree Canopy to assess tree cover within 2 miles of specific points in Africa. To do this, I need a quick way to use "Define project area" to draw a near circular polygon (an octagon would suffice) around each point. How can I do this? Can I define the polygon once...
