Convert x-coordinates and y-coordinates given in Albers projection to latitude and longitude in Clarke1866, GRS80 or WGS84 spheriod with specified parameters.
albersgeod(x, y, sph = "GRS80", clon = -96, clat = 23, sp1 = 29.5,
sp2 = 45.5)
Vector of Albers x-coordinates to be projected to latitude/longitude.
Vector of Albers y-coordinates to be projected to latitude/longitude.
Spheroid options: Clarke1866, GRS80, WGS84. The default is GRS80.
Center longitude (decimal degrees). The default is -96.
Origin latitude (decimal degrees). The default is 23.
Standard parallel 1 (decimal degrees). The default is 29.5.
Standard parallel 2 (decimal degrees). The default is 45.5.
