132< <formula>Note: These formulas have been transcribed from EPSG Guidance Note #7-2. Users are encouraged to use that document rather than the text which follows as reference because limitations in the transcription will be avoided.
133<
134< The forward case is trivial. A 3-dimensional geographic coordinate reference system comprising of geodetic latitude, geodetic longitude and ellipsoidal height is converted to its 2-dimensional subset by the simple expedient of dropping the height.
135<
136< The reverse conversion, from 2D to 3D, is indeterminate. It is however a requirement when a geographic 2D coordinate reference system is to be transformed using a geocentric method which is 3-dimensional. In practice an artificial ellipsoidal height is created and appended to the geographic 2D coordinate reference system to create a geographic 3D coordinate reference system referenced to the same geodetic datum. The assumed ellipsoidal height is usually either set to the gravity-related height of a position in a compound coordinate reference system, or set to zero. As long as the height chosen is within a few kilometres of sea level, no error will be induced into the horizontal position resulting from the later geocentric transformation; the vertical coordinate will however be meaningless.</formula>

297< <epsg:example>Consider a North Sea point with coordinates derived by GPS satellite in the WGS 84 geographical coordinate system with coordinates of:
298<
299< latitude 53 deg 48 min 33.82 sec N,
300< longitude 02 deg 07 min 46.38 sec E,
301< and ellipsoidal height 73.0m,
302<
303< whose coordinates are required in terms of the ED50 geographical coordinate system which takes the International 1924 ellipsoid. The three parameter datum shift from WGS 84 to ED50 for this North Sea area is given as dX = +84.87m, dY = +96.49m, dZ = +116.95m.
304<
305< The WGS 84 geographical coordinates convert to the following geocentric values using the above formulas for X, Y, Z:
306<
307< XA = 3771 793.97m
308< YA = 140 253.34m
309< ZA = 5124 304.35m
310<
311< Applying the quoted datum shifts to these, we obtain new geocentric values now related to ED50:
312<
313< XB = 3771 878.84m
314< YB = 140 349.83m
315< ZB = 5124 421.30m
316<
317< These convert to ED50 values on the International 1924 ellipsoid as:
318< latitude 53 deg 48 min 36.565 sec N,
319< longitude 02 deg 07 min 51.477 sec E,
320< and ellipsoidal height 28.02 m,
321<
322< Note that the derived height is referred to the International 1924 ellipsoidal surface and will need a further correction for the height of the geoid at this point in order to relate it to Mean Sea Level.</epsg:example>

326< <remarks>This is a parameter-less conversion. In applications it is often concatenated with the 3- 7- or 10-parameter transformations 9603, 9606, 9607 or 9636 to form a geographic to geographic transformation.</remarks>

328<
329< Latitude, P, and Longitude, L, in terms of Geographic Coordinate Reference System A may
330< be expressed in terms of a geocentric (earth centred) Cartesian coordinate reference system X, Y, Z
331< with the Z axis corresponding with the Polar axis positive northwards, the X axis through
332< the intersection of the Greenwich meridian and equator, and the Y axis through the
333< intersection of the equator with longitude 90 degrees E. If the prime meridian for geogCRS A is not
334< Greewich, longitudes must first be transformed to their Greenwich equivalent. If the earth's
335< spheroidal semi major axis is a, semi minor axis b, and inverse flattening 1/f, then
336<
337< X = (nu + h) cos P cos L
338< Y = (nu + h) cos P sin L
339< Z = ((1 - e^2) nu + h) sin P
340<
341< where nu is the prime vertical radius of curvature at latitude P and is equal to
342< nu = a /(1 - e^2*sin^2(P))^0.5,
343< P and L are respectively the latitude and longitude (related to Greenwich) of the point
344< h is height above the ellipsoid, (topographic height plus geoidal height), and
345< e is the eccentricity of the ellipsoid where e^2 = (a^2 -b^2)/a^2 = 2f -f^2
346<
347< Cartesian coordinates in geocentric coordinate reference system B may be used to derive geographical coordinates in terms of geographic coordinate reference system B by:
348<
349< P = atan[(Z + eta b sin^3 q) / (p ? e^2 a cos^3 q)]
350< L = atan (Y/X)
351<
352< where
353< eta = e^2 / (1 ? e^2)
354< b = a(1 ? f)
355< p = (X^2 + Y^2)^0.5
356< q = atan[(Z a) / (p b)]
357<
358< and where L is relative to Greenwich. If the geographic system has a non Greenwich prime meridian, the Greenwich value of the local prime meridian should be applied to longitude.
359<
360< Then
361< h (p / cos P) ? nu
362<
363< (Note that h is the height above the ellipsoid. This is the height value which is delivered by Transit and GPS satellite observations but is not the topographic height value which is normally used for national mapping and levelling operations. The topographic height is usually the height above mean sea level or an alternative
364< level reference for the country. If one starts with a topographic height, it will be necessary to convert it to an ellipsoid height before using the above transformation formulas. h = N + H, where N is the geoid height above the ellipsoid at the point and is sometimes negative, and H is the height of the point above the geoid. The height above the geoid is often taken to be that above mean sea level, perhaps with a constant correction applied. Geoid heights of points above the nationally used ellipsoid may not be readily available. For the WGS84 ellipsoid the value of N,
365< representing the height of the geoid relative to the ellipsoid, can vary between values of -100m in the Sri Lanka area to +80m in the North Atlantic.)</formula>
