Will The Store Locator Accept Longitude and Latitude?

This can be achieved in two ways:

You can import locations from an Excel spreadsheet. 

Log into your store admin

Go to Store Locator by W3 in Apps

Select "Import" in the task bar

Choose the file with the locations you want to import. 

If you enter a location manually, the app will find the longitude and latitude for you. 

You can edit the location and see the longitude and latitude at the bottom of the page.

In some cases, the location maker will be displayed slightly off from the EXACT location. 

In the event you experience this, you are able to manually drag and drop the marker to the precise location. 

Make sure to to click the blue "Save Location" button after any changes.
