I have a list of lat/lon coordinates for data points that I want to put on a map. I want to have the size and/or color of the points to change based on additional columns on the excel sheet with the coordinates (kind of like a bubble chart). Is it possible to do this in GIS? I am using arcmap 10.2.

  • If you have ArcGIS Online you can map directly from Excel using ArcGIS Maps for Office which I think will do what you're wanting – Midavalo Jul 28 '16 at 3:15

This is quintessential gis. The process depends on your available software.

You could start either process by importing csv with your x/y values and the symbology fields.
