Adding a Geolocation column to a list in SharePoint 2013 is a bit of a pain because there’s no built-in user interface to do so.  Instead, you have to add it with code.  Check out Tobias Zimmergren’s article to get acquainted with the Geolocation column in SharePoint 2013:  http://zimmergren.net/technical/sp-2013-getting-started-with-the-new-geolocation-field-in-sharepoint-2013.

Now, to the point of my post, I’ve just launched a project on CodePlex to provide a UI for Geolocation management in SharePoint 2013.  Ideally this will work in both on-premises and online environments.

As this is a new effort, it’s currently in beta and needs a lot of work to be truly awesome.  That said, check out the project here:  http://sp2013geolocationmanager.codeplex.com/.  I appreciate any and all feedback.  You can reach me at eric.skaggs@catapultsystems.com or eskaggs@outlook.com.
