Web AppBuilder: "My Location" - Widget

JohannesFuchs — Wed, 08 Apr 2015 06:29:49 GMT

Hi all,

in all web apps built with Web AppBuilder you can perform the "my location" widget. I am interested in the sources used in this widget to find the actual position of the user. Is it the GPS signal of the mobile device and surrounding wifi? Is it just GPS? Are the same sources used as in, for example, Google maps? Is there any difference?

I could not find any Information so far in the ressources. It would be great if you can give me a hint!

Thanks in advance,

Johannes

Johannes,

In the context of Web App Builder, it is very dependent on the device being used. WAB is using the JavaScript API's LocateButton which gets position information from navigator.geolocation specification. So on an iPhone it would be getting a GPS feed that would be further improved with a WiFi connection. The iPhone could be connected to a higher quality GPS unit via bluetooth and get even better quality positioning.

You can find more information about the navigator.geolocation specification at:

Geolocation API Specification

Tom
