I live on a volcano. I see much greater than 40 mm offsets in the
sidewalks around my house from year to year.
Can you be more specific about "height". gpsd reports two types of
"height". Altitude MSL (altMSL) and Altitude Hgeight Above Ellipsoid
(altHAE). altMSL is very sensitive to the date of your gravity model.
altHAE is much less sensitive, but does seem to change yearly or so.
