Detailed Description

template<typename T>
class cuproj::vec_2d< T >

A generic 2D vector type.

This is the base type used in cuspatial for both Longitude/Latitude (LonLat) coordinate pairs and Cartesian (X/Y) coordinate pairs. For LonLat pairs, the x member represents Longitude, and y represents Latitude.

Template Parameters

T	the base type for the coordinates
