Hello, APM users 
Guys from DIYDrones recomend to ask here.
As we knew during flight planing we could see altitude of each terrain point on map loaded (right up corner of flight plan tab), besides program knew home position altitude (right low corner at the same tab), at last with full telemetry link program knew altitude of our drone in each moment of flight (absolute or home position relative).
My question is - is any possibility to see altitude over terrain instantly during flight ?
Picture to illustrate my question could be found here:

Thank you.
