[TDWG-BDQ] Accuracy of Elevation (and georeference) from Smartphones and GPS

I've invited you to fill out the following form:
Accuracy of Elevation (and georeference) from Smartphones and GPS

To fill it out, visit:

Sometime back, we sent around a form with a request to do some tests on  
your GPS or Smartphone for us.

I have had a very poor response so far, and was hoping that you could take  
10 minutes to carry out some tests for us.  If you are unable to find a  
spot height or trig point, then use an identifieable point and report  
against Google Earth as requested.

We are asking for this, because many of the published results are from the  
USA or Europe, and we would like to get a good data set from a range of  
locations.  Some testing I did recently on an outer island of Fiji gave  
much worse results for elevation than we expected, although horizontal  
accuracy was reasonable.

Details are below
