GeoTransform class Projections

Transforms are a generalization of projections.

Transform implement GeoProjection.stream and can be passed to GeoPath.transform. However, transform only implements a subset of the other projection methods, and represent arbitrary geometric transformations rather than projections from spherical to planar coordinates.

Implementers

• GeoIdentity
• GeoProjection
