PoR2Geo_azimuth: Azimuth conversion from PoR to geographical coordinate reference system

Description

Conversion of PoR azimuths into geographical azimuths

Usage

PoR2Geo_azimuth(x, PoR)

Value

numeric vector of transformed azimuths (in degrees)

Arguments

x

data.frame containing the PoR equivalent azimuths (azi.PoR), and either the geographical coordinates of the point(s) or the PoR-equivalent coordinates.

PoR

data.frame containing the geographical location of the Euler pole (lat, lon)
