Expand description
This module provides an Elevation type, crate::elv! macro, and a CoordinateWithElevation
structure which is a lat/long Coordinate with an associated elevation.
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth’s sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum).
The reference point for the type Elevation is not defined, therefore any absolute value must
be calculated by conversion from convention in reference to some datum.
Structs§
- Coordinate
With Elevation - A three dimensional geographic coordinate expressed as a (latitude, longitude, elevation) triple.
- Elevation
- An elevation, in meters, above or below an undefined reference level.
