Could you add more information? For example, which software are you using? How are the coordinates stored (text, table, shapefile)? There many different tools to achieve this task, and it is a lot easier to explain in whatever software platform you are using than trying to cover all possibilities.

Could you update the link to the proceeding, the one you posted is no longer available (page not found). Alternatively, you could place a title or some information that would allow us to search for it at the ESRI page.
