eckit::geo::PointLonLat class final

#include <eckit/geo/PointLonLat.h>

The PointLonLat class.

A point on a geographic coordinate system, in (longitude, latitude) coordinates [degree]; They are fully circular in space (also latitude), longitude is typically limited to [0, 360[ and latitude to [-90, 90], with normalisation functions available, as well as conversion to and from radian-based coordinates.
