Linear

Description

Name

class Tinman.Georef.DatumOp.Linear

Derived from

DatumOp

Linearly transforms 3D geographic coordinates.

For the given input coordinates (lambda, phi, h), the transformation will give:
(lambda + longitude, phi + latitude, h * scale + offset) This method represents the following:

  • EPSG-1131: Geog3D to Geog2D+GravityRelatedHeight

  • EPSG-1136: Geographic3D to GravityRelatedHeight

  • EPSG-9601: Longitude rotation

  • EPSG-9616: Vertical Offset

  • EPSG-9618: Geographic2D with Height Offsets

  • EPSG-9619: Geographic2D offsets

  • EPSG-9660: Geographic3D offsets
