code::LatLonGrid code::Data2D< T3, T4, X > code::DataType code::Dim2D< X > List of all members.

Detailed Description

Store an area of heights as a LatLonGrid.

This class over-rides the reference methods of a LatLonGrid to set the height.

The data, though "raw" floats/doubles, should represent meters.
