/**
 * # Transverse Mercator
 *
 * **Classification**: Transverse and oblique cylindrical
 *
 * **Available forms**: Forward and inverse, spherical and ellipsoidal
 *
 * **Defined area**: Global, with full accuracy within 3900 km of the central meridian
 *
 * **Alias**: tmerc
 *
 * **Domain**: 2D
 *
 * **Input type**: Geodetic coordinates
 *
 * **Output type**: Projected coordinates
 *
 * ## Projection String
 * ```
 * +proj=tmerc
 * ```
 *
 * ## Required Parameters
 * - `+lon_0`: Longitude of the central meridian.
 *
 * ## Optional Parameters
 * - `+approx`: Use the faster Evenden-Snyder algorithm, less accurate beyond 3°.
 * - `+algo`: Select algorithm from "auto", "evenden_snyder", or "poder_engsager".
 * - `+lat_0`: Latitude of origin.
 * - `+k_0`: Scale factor on the central meridian.
 * - `+x_0`: False easting.
 * - `+y_0`: False northing.
