albersgeod: Project Albers Projection in Plane to Latitude and Longitude (Spheroid)

Description

Project Albers projection in the plane to spheroid models of the globe.

Usage

albersgeod(x, y, sph="GRS80", clon=-96, clat=23, sp1=29.5, sp2=45.5)

Arguments

x

Albers x-coordinate vector to be projected to latitude/longitude.

y

Albers y-coordinate vector to be projected to latitude/longitude.

sph

spheroid options: Clarke1866, GRS80, WGS84. The default is GRS80.

clon

center longitude (decimal degrees). The default is -96.

clat

origin latitude (decimal degrees). The default is 23.

sp1

standard parallel 1 (decimal degrees). The default is 29.5.

sp2

standard parallel 2 (decimal degrees). The default is 45.5.

Value

A data frame of latitude and longitude projections for Albers x-coordinates and y-coordinates.
