Collecting Data - Location
When a form requires a Locatin field (eg GPS), presuming a user has GPS turned on and also that the devices GPS device has obtained a fix, they can add these data to the form (Please read notes below). The following screenshots show how a user adds a location to the form.
Firstly, the user is presented with a button titled 'Tap to Set Location' Tapping this button will acquire the current location of the device and enter details in the text box below the button.
The information recorded is as follows:
Accuracy: Returns the accuracy of the location fix in metres
Note: By default, location is acquired using the mobile devices inbuilt GPS. However, 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 true 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.
