Setting up geo_point

Hi, sorry if this is too much of a newbie question, but where do I target the curl command that places the mapping for enabling of the geopoint in Sense? As I am attempting to create tile map visualizations from the packetbeat index pattern. I realize that I need to create the geo_point field type, but I'm not sure how even after reading the documentations.

This is an ES based question, so let me move it over there.
