Synopsis

data GridTM e
mkGridTM :: Ellipsoid e => Geodetic e -> GridOffset -> Double -> GridTM e

Documentation

data GridTM e Source #

A Transverse Mercator projection gives an approximate mapping of the ellipsoid on to a 2-D grid. It models a sheet curved around the ellipsoid so that it touches it at one north-south line (hence making it part of a slightly elliptical cylinder).

The calculations here are based on "Transverse Mercator Projection: Constants, Formulae and Methods" by the Ordnance Survey, March 1983. Retrieved from http://www.threelittlemaids.co.uk/magdec/transverse_mercator_projection.pdf
