Create a new wagner_vii projection

Parameters:

  • context (Context) —

    Proj Context

  • center_longitude (Float) —

    Longitude of natural origin/Central Meridian

  • false_easting (Float) (defaults to: 0) —

    False Easting. Default is 0.

  • false_northing (Float) (defaults to: 0) —

    False Northing. Default is 0.

  • angular_unit_name (String) (defaults to: "Degree") —

    Name of the angular units. Default is Degree.

  • angular_unit_conversion_factor (Float) (defaults to: 0.0174532925199433) —
