Struct GstmercData 

pub struct GstmercData { /* private fields */ }

Gauss-Schreiber Transverse Mercator (aka Gauss-Laborde Reunion)

Classification: Conformal

Available forms: Forward and inverse, spherical projection

Defined area: Global

Alias: gstmerc

Domain: 2D

Input type: Geodetic coordinates

Output type: Projected coordinates

Projection String

+proj=gstmerc

Optional Parameters

• +k_0=<value>: Scale factor at the central meridian.
• +lon_0=<value>: Longitude of the central meridian.
• +lat_0=<value>: Latitude of origin.
• +ellps=<value>: Ellipsoid name (e.g., GRS80, WGS84).
• +R=<value>: Radius of the sphere (used in spherical projections).
• +x_0=<value>: False easting.
• +y_0=<value>: False northing.

Usage Example

echo 12 55 | proj +proj=gstmerc +ellps=WGS84
echo 12 55 | proj +proj=gstmerc +k_0=1 +lon_0=0 +x_0=500000 +y_0=0

Trait Implementations

impl Clone for GstmercData

fn clone(&self) -> GstmercData

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GstmercData

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GstmercData

fn default() -> GstmercData

Returns the “default value” for a type.

impl PartialEq for GstmercData

fn eq(&self, other: &GstmercData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
