Hello,
Sorry for my poor english.

Is it possible having 2 news functions please ?

• TinyGPSPlus::altitudeBetween
• TinyGPSPlus::lastInclination

TinyGPSPlus::altitudeBetween :
how many meters between 2 altitudes

TinyGPSPlus::lastInclination :
combinate TinyGPSPlus::distanceBetween and TinyGPSPlus::altitudeBetween to calculate TinyGPSPlus::lastInclination(lat1,lon1,alt1,lat2,lon2,alt2,incl) with incl='D' in degree (as inclinometer) or incl='P' in %(as road board) ?

TinyGPSPlus::lastInclination can help when is night, or big fog to understand why car's speed is low...

Maybe an library exist for sky driving or for drone pilote giving from GPS data altitudeBetween and lastInclination and can be used ?

Thank you.

I have a question : the TinyGPSPlus::distanceBetween is it right on montain roads ?
