AirMap Vs B4UFly Vs Kittyhawk

[lookout]

Isn't class E airspacce starting at 700 or 1,200’ AGL? The space under in many areas is class G, I think.

Class E can go down to surface if otherwise specified, but I think it is typically 700' AGL.

Class G is the "other airspace".

Class E airspace exists in many forms.
It can serve as a surface-based extension to Class D airspace to accommodate IFR approach/departure procedure areas.
Class E airspace can be designated to have a floor of 700' AGL or 1,200' AGL, or a customized floor of any other altitude.
Class E airspace exists above Class G surface areas from 14,500' MSL to 18,000 MSL.
Federal airways from 1,200 AGL to 18,000 MSL within 4 miles (6 km) of the centerline of the airway are designated Class E airspace.
Airspace at any altitude over FL600 (60,000 MSL) (the ceiling of Class A airspace) is designated Class E airspace.
