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

Description

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

Usage

geodalbers(lon, lat, sph="GRS80", clon=-96, clat=23, sp1=29.5, sp2=45.5)

Arguments

lon

longitude (decimal degrees) vector to be projected using Albers.

lat

latitude (decimal degrees) vector to be projected using Albers.

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 Albers x-coordinate and y-coordinate projections for latitude and longitude.
