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.
To derive the projected coordinates of a point, geodetic latitude (lat) is converted to authalic latitude (ß). The formulas to convert geodetic latitude and longitude (lat, lon) to Easting (E) and Northing (N) are:
Easting (E) = EF + (rho . sin(theta))
Northing (N) = NF + rhoO ? (rho . cos(theta))
where
theta = n . (lon - lonO)
rho = [a . (C ? n.alpha)^0.5] / n
rhoO = [a . (C ? n.alphaO)^0.5] / n
and
C = m1^2 + (n . alpha1)
n = (m1^2 ? m2^2) / (alpha2 - alpha1)
m1 = cos lat1 / (1 ? e^2 sin^2(lat1))^0.5
m2 = cos lat2 / (1 ? e^2 sin^2(lat2))^0.5
alpha = (1 ? e^2) . {[sin(lat) / (1 ? e^2 sin^2(lat))] ? [1/(2e)] . ln [(1 ? e sin(lat)) / (1 + e sin(lat))]}
alphaO = (1 ? e^2) . {[sin(latO) / (1 ? e^2 sin^2(latO))] ? [1/(2e)] . ln [(1 ? e sin(latO)) / (1 + e sin(latO))]}
alpha1 = (1 ? e^2) . {[sin(lat1) / (1 ? e^2 sin^2(lat1))] ? [1/(2e)] . ln [(1 ? e sin(lat1)) / (1 + e sin(lat1))]}
alpha2 = (1 ? e^2) . {[sin(lat2) / (1 ? e^2 sin^2(lat2))] ? [1/(2e)] . ln [(1 ? e sin(lat2)) / (1 + e sin(lat2))]}
The reverse formulas to derive the geodetic latitude and longitude of a point from its Easting and Northing values are:
lat = ß' + (e^2/3 + 31e^4/180 + 517e^6/5040) . sin 2ß'] + [(23e^4/360 + 251e^6/3780) . sin 4ß'] + [(761e^6/45360) . sin 6ß']
lon = lonO + (theta / n)
where
ß' = asin(alpha' / {1 ? [(1 ? e^2) / (2 . e)] . ln [(1 ? e) / (1 + e)]
alpha' = [C ? (rho^2 . N^2 / a^2)] / n
rho = {(E ? EF)^2 + [rhoO ? (N ? NF)]^2 }^0.5
theta = atan [(E ? EF) / [rhoO ? (N ? NF)]
and C, n and rhoO are as in the forward equations.
