Why this package ?
Gryd package provides efficient great circle computation and projection library.
They are two related iterative methods used in geodesy to calculate the distance between two points on the surface of a spheroid.
All epsg dataset linked to these projections are available through python API using epsg id or name. Available projections are Mercator, Transverse Mercator and Lambert Conformal Conic.
The four main grids are available : Universal Transverse Mercator, Military Grid Reference System, British National Grid and Irish National Grid.
Gryd.Crs class also provides functions for map coordinates
interpolation using calibration points. Two points minimum are
