por_transformation_df function

Conversion between spherical PoR to geographical coordinate system of data.frames

Transformation from spherical PoR to geographical coordinate system and vice versa

geographical_to_PoR_df(x, PoR)

PoR_to_geographical_df(x, PoR)

Arguments

• x: "data.frame" containing lat and lon

  coordinates of a point in the geographical CRS or the lat.PoR, lon.PoR) of the point in the PoR CRS.

• PoR: Pole of Rotation. "data.frame" or object of class "euler.pole"

  containing the geographical coordinates of the Euler pole

Returns

"data.frame" with the transformed coordinates (lat.PoR and lon.PoR for PoR CRS, or lat and lon for geographical CRS).
