Enumerator
Geodetic	A geodetic reference system is a reference based on a geodetic datum. Coordinates in these references correspond with longitude, latitude and height values. Longitude and latitude values are expressed in degrees, height values in meters.
Grid	A grid reference (or projected reference) is a cartesian reference that contains the relation between its (x, y, z) coordinates and the corresponding geodetic (longitude, latitude, height) coordinates. (x, y) is a regional Easting-Northing pair while z is equal to the original height. The Easting coordinate (x) is positive for East and negative for West. The Northing coordinate (y) is positive for North and negative for South.
Geocentric	A geocentric reference is a cartesian reference based on a geodetic datum. Coordinates are expressed in (x,y,z) with regard to the center of the ellipsoid on which the geodetic datum is based.
Topocentric	A topocentric reference is a cartesian reference that is defined by a geodetic datum and a lon-lat-height point that defines the origin of the reference. A topocentric coordinate system is a right-handed cartesian coordinate system with the following properties: Its origin is defined by a lon-lat-height point on the ellipsoid. The y-axis is directed northwards and aligned to intersect with the polar rotational axis of the ellipsoid. The x-axis if directed eastwards. The x-y plane is tangential to the ellipsoid at the origin. The z-axis is perpendicular to the ellipsoid at the origin, and points outwards. In other words, the z-axis is perpendicular to the x-y plane. This reference is also referred to as an ENU (East-North-Up) projection.

LineInterpolationType

enum Luciad.Geodesy.LineInterpolationType

Line type: geodesics vs rhumbs vs linear.

Enumerator
Geodesic	Geodesic interpolation between points.
Rhumb	Rhumbline interpolation between points.
Linear	Linear interpolation between points.
