I am using vector data from a CSV file and ArcGIS.

I can use the Geoprocssing tool Buffer just fine, I use these parameters

enter image description here

and ArcGIS does produce what I want, however it is way to small (my data is extremely varied, lots of low and high numbers).

enter image description here

I can't seem to figure how I can increase the size of each circle equally?

EDIT: The numbers I am using are observed values, fairly certain they are ratio or at the very least interval. It's how many times a death occurred with-in a certain area during a specific year (the numbers in the second image are the different areas)

  • what are those numbers? if they're frequencies you could use graduated symbols rather than buffering the points – Adam Dec 10 '15 at 2:31

    ok, so I would use graduated symbols, set the minimum and maximum size for the symbols and let arcmap sort out the sizes – Adam Dec 10 '15 at 2:47
  • Okay, so I've Jerry Rigged a solution. Inside my data set's attribute table, I just created another field called Times10, used the field calculator to set it as the data I wish to buffer and multiplied it by 10. I keep increasing the value until there was decent overlap. I am trying to think if this will affect my analysis (as 109 * 22 >>>>> than 3 * 22). – Mareykan Dec 10 '15 at 2:59

    I'd follow @Adam suggestion. Create point dataset and use your field for graduated symbols – FelixIP Dec 10 '15 at 6:26

It's not really correct to use buffers when what you actually want to display is the importance of points. So please follow the suggestion of using graduated symbols instead of creating a new layer with areas!

In addition it's much easier to adapt you don't need to create a new layer, add fields and recalculate them each time you want to change the style :)

  • Would I be able to use the Intersect analysis tool on the graduate symbols to find the overlap between all the different symbols? – Mareykan Dec 10 '15 at 19:21
  • No, you couldn't, but that doesn't seem like a valid analysis of a count of an occurrence. – Adam Dec 11 '15 at 4:41
  • Oh, I am trying to find/select/measure the overlap of each buffer zone/graduated symbol. – Mareykan Dec 11 '15 at 5:59
