The “Geo-Location” setting controls whether you see the “My Location” symbol on maps. This symbol will appear if your smartphone or tablet device supports Geo-positioning, that is, the device is capable of determining its own the location. See the explanation of eTourChatham Geo-Location on the eTour Maps Behavior page, for an understanding of how it works. The default for this option is “Yes”, so if your device supports Geo-positioning, you will normally see the “My Location” symbol on a map.
If you set this option to “No”, the “My Location” symbol will not be shown. This may be appropriate if you never intend to use Geo-Location on an eTourChatham map.
