Struct TransverseMercator

pub struct TransverseMercator { /* private fields */ }

Available on crate feature std only.

An implementation of the Transverse Mercator map projection.

This implementation uses the expansions contained within DMA TM 8358.2, however, 8358.2 has issues with how the ‘Meridional Distance’ is calculated. As such, to get full proper nanometer accuracy, the [crate::geo::ellipsoid::DeakinHunterKarneyMeridianCalculator] is used to calculate meridian arc length.

Using the map center returned by Default is not recommended, as it is unlikely to be useful to your specific application. Recommend ALWAYS setting a map projection center to be within +/- 6 degrees of your chosen area of interest. 6 degrees gives an excellent error factor, and as you get further from the map center, the error increases exponentially.
