GPS component

An administrator can add the GPS component into a form giving the responder the ability to accurately state their location.

When using GPS, you can decide the minimum level of accuracy required when collecting GPS coordinates out in the field.

It is important to remember that adding a GPS location is strictly based on coordinates given to you via a GPS satellite. This is not to be confused with wifi location coordinates (which are less accurate).

With this in mind, when adding the GPS component to your forms, you can choose between three minimum levels of accuracy:

  • Any             Location Precision (Checks the device GPS, Wifi & Mobile data   location, no accuracy limits set)
  • Medium      Require GPS (Set as default - Checks GPS only - within 100 metres)
  • High           Maximum Precision (Checks GPS only, within 20 metres, slower)

The differences between these options are purely based on your requirements.

Examples for Any Accuracy

  • If you are working with low specification devices that do not contain a GPS module (this can be the case in certain Android devices)
  • Your survey is being processed inside buildings or within urban areas with tall buildings - where it might be more difficult to acquire the GPS signal.

Examples for Medium Accuracy (default option)

  • You require a standard location and you want to be sure that it has a minimum level of accuracy.
  • If you are not sure, just simply set Medium as the default and confirm the results are sufficient.

Examples for High Accuracy

  • If you need to collect more exact coordinates of a location of interest. Then use the High option. This will work only when you can see the sky without any physical barrier.

 

When the select on map option is enabled, you can choose the coordinates within the map view.

The minimum level of accuracy is applied for Android devices only, it will be added to the iOS app later. Please, let us know if this is a requirement on iOS and we will speed up the development.
