Store HDOP in logs #145

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
It would help if HDOP (VDOP,PDOP) or some accuracy infomation is stored into 
GPX logs.
http://en.wikipedia.org/wiki/HDOP

This could be used to filter inaccurate data from logs.

VDOP or PDOP information is not exposed through the API. Accuracy information 
is available as single deviation in meters number. 

Would adding that number in the GPX logs as extension help?

It would be helpful to filter out all inaccurate data. For example with minimal 
accuracy setting, don't store data with accuracy worse than 20 (5,10,50,100) 
meters.

It already does just that.
