specfem::coordinate_systems

namespace coordinate_systems

The specfem::coordinate_systems namespace provides coordinate types and map projections for geodetic I/O. Include via #include "specfem/coordinate_systems.hpp".

Coordinate types

• geographic_coordinates: Longitude/latitude in degrees, depth in meters.

• cartesian_coordinates: x/y/z in meters (easting/northing/depth for UTM).

• geocentric_coordinates: Spherical \((r, \theta, \phi)\) coordinates.

Transforms

• specfem::coordinate_systems::transform: Generic transform<Target>(source, config) interface for converting between coordinate systems.

Projections

• UTM projection: UTM (Universal Transverse Mercator) forward and inverse projection.

• specfem::coordinate_systems::geographic_coordinates
• specfem::coordinate_systems::cartesian_coordinates
• specfem::coordinate_systems::geocentric_coordinates
• specfem::coordinate_systems::transform
• UTM projection
