Convert coordinates from degrees to radians — ga_to_radians • geoarrowrs

Multiplies every x and y coordinate by pi / 180. ga_to_radians() keeps the geometry type of the input.

Usage

ga_to_radians(geometry)

Arguments

geometry: a GeoArrow geometry array

Value

a GeoArrow array of the same geometry type as the input

Details

ga_to_radians() converts only the x and y coordinates. It drops Z and M values, since it goes through a two dimensional representation.

Examples

deg <- ga_point(c(0, 45), c(0, 90))

geoarrow::as_geoarrow_vctr(ga_to_radians(deg))
#> <geoarrow_vctr geoarrow.point{struct}[2]>
#> [1] <POINT (0 0)>                 <POINT (0.7853982 1.5707963)>
