Most Accurate Altitude Settings
Answered
I read through the FAQ/help but it was a bit too technical. What settings should I use for the most accurate altitude information when recording tracks? I did enable the pressure sensor setting and checked optimize gps measured elevation. Currently I have "use altitude offset off". Is this the most accurate configuration? I am using a nexus 5 phone.
thanks!

Hi Clayton,
the discussion about GPS measured altitude is a never-ending story. Locus does provide many options how to optimize it, however, you'll never get absolutely accurate results. There's one obvious rule - the more manual settings you apply, the more accurate values you get (but the less universal the measurement is). So, set manually actual pressure at a particular sea level, set manual correction of altitude offset and you'll get the most Locus can measure. But keep in mind that such settings apply only in a limited area and in limited time (air pressure changes).

Thanks Michal. That makes sense. I'm fine with calibrating it before I head out. I mainly want more accurate altitude for when I'm recording a track skiing because the satellite altitude can jump hundreds of feet at a time. I'll see if these settings make things smoother. Cheers

For devices with barometer, there is still a development idea to combine short term stability and accuracy of barometer height and long term stability and accuracy of GPS height.
Short term altitude changes would be gained from the barometer, while long term barometer height drift ( due atmospheric pressure changes ) would be adjusted according to barometer versus GPS height mean difference.
