eckit::geometry::Point2 class

#include <eckit/geometry/Point2.h>

Base classes

template<int SIZE = 2>

class KPoint<2>

A generic point in K dimension cartesian space.

Derived classes

class atlas::PointLonLat

Point in longitude-latitude coordinate system. This class does not normalise the longitude by default, but contains a normalise function.

class atlas::PointXY

Point in arbitrary XY-coordinate system.
