Looking inside

A drab wet day so much better to turn the lens indoors, even if it is for a vaguely arty shot. Perhaps also a small nod to 80s Bowie in there.

After a very broken day in the office, more thoughts on Tracker this evening, with barometric altitude now in the code I can do some useful filtering of gps height errors. Lots of tuning and algorithms to play with, this is where Excel gets fun. Magic :-)
