Location (GPS position or wireless / phone mast triangulation)

 

<location ref="locationOfHandset" required="true"> 

   <label>Please record Location</label> 

</location>

By default, location is acquired using the mobile device's inbuilt GPS. This requires that GPS is enabled on the device.

To enable GPS on your device you should go to the 'Settings' menu and then 'Location' and turn GPS on.

When your phone's GPS is acquiring a fix, the GPS icon will appear in the bar at the top of your screen. This icon will be flashing when acquiring a position and when acquired will remain solid (as below.)

If GPS is not enabled, EpiCollect+ will attempt to ascertain a location using other methods. Firstly, if you are connected to a wireless network, an IP Lookup is undertaken to try to determine location, otherwise, if you are connected to a mobile network, triangulation can be used to acquire a location. It should be noted that the accuracy achievable with these methods is less than using the phone's GPS.

To only allow GPS, we recommend turning off the 'use wireless networks' option on the devices location settings. This will not allow location to be determined by either wireless and/or mobile networks triangulation.


When a location is detected, the latitude. longitude and altitude of the device are stored within the database (and you will see these at the central server). In conjunction, an accuracy of location is returned, based on the method used. The accuracy is presented to the user as in the screenshot below. A user may then proceed to the next question or, by tapping 'tap again to update', can update the location to, for example, achieve a desired accuracy.

You can also use the required="true" attribute within the <location> tag.
