Mapit for JIra is an add-on for Jira Server and Data Center that displays Jira issues in a map gadget, and allows users to create issues directly from the map. 

By geotagging Jira issues, your users can keep track of the exact location where the work needs to be done, or where the issue originated from.
Geotagging means adding geographic latitude and longitude to your Jira issues.

The below pages will give you a guide to how to configure the Mapit add-on.
