Module geodesy.projection.pseudo_mercator
Bounded EPSG 1024 Popular Visualisation Pseudo-Mercator projection.
This module provides the familiar web-mapping projection as an explicit bounded mathematical operation rather than a CRS database entry. The source ellipsoid is retained as operation identity, while EPSG 1024 coordinate equations intentionally use only its semi-major axis.
Standards
EPSG method 1024 -- Popular Visualisation Pseudo Mercator.
Domain
Public latitude is deliberately bounded to the documented geodesy-d interval rather than implying validity arbitrarily close to the poles.
Units
Projected coordinates and false offsets use the same linear unit as the ellipsoid semi-major axis.
Performance
Prepared operation state is reusable and checked numerical paths are allocation-free.
Validation
Covered by public API/runtime validation and independent differential projection tests retained by the repository.
