por_transformation_sf {tectonicr}

Conversion between PoR to geographical coordinates of spatial data

Description

Transform spatial objects from PoR to geographical coordinate reference system and vice versa.

Usage

PoR_to_geographical_sf(x, PoR)

geographical_to_PoR_sf(x, PoR)

Arguments

x

sf, SpatRast, or Raster* object of the data points in geographical or PoR coordinate system

PoR

Pole of Rotation. "data.frame" or object of class "euler.pole" containing the geographical coordinates of the Euler pole

Details

The PoR coordinate reference system is oblique transformation of the geographical coordinate system with the Euler pole coordinates being the translation factors.

Value

sf or SpatRast object of the data points in the transformed geographical or PoR coordinate system

Examples

data("nuvel1")
PoR <- subset(nuvel1, nuvel1$plate.rot == "na") # North America relative to Pacific plate
data("san_andreas")
san_andreas.por <- geographical_to_PoR_sf(san_andreas, PoR)
PoR_to_geographical_sf(san_andreas.por, PoR)
