I’m trying to create a points form using the user’s current location, but the coordinates provided are inaccurate by 20, 30, or even 40 meters, which compromises the effectiveness of the search. What can I do to minimize this inaccuracy as much as possible?
Here’s a couple article on things you might try to improve your GPS acquisition accuracy:
If you are not already, I would highly recommend adding a start-geopoint question to your form. This will fire up the device’s GPS hardware as soon as you start the form and start looking for satellites; the more satellites detected and locked onto the higher the accuracy. So hopefully by the time you get to your actual geopoint question it will already have a good fix.
You can also specify a custom required accuracy, which will override the default of 5m. However, if you set this too tight (eg 1m) you might not actually be able to achieve it in the field.
If you require extreme accuracy, on the order of 1-10cm, then you might also consider hooking a high precision external GPS sensor to your Android device via Bluetooth (via a mock location provide) and KoboCollect will use it instead; eg How to use centimeter GPS with any Android app (mock location) - ArduSimple
