albersgeod: Project Albers Projection in Plane to Latitude and Longitude...

In mhweber/spsurvey: Spatial Survey Design and Analysis

Description

Convert x-coordinates and y-coordinates given in Albers projection to latitude and longitude in Clarke1866, GRS80 or WGS84 spheriod with specified parameters.

Usage

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

Arguments

x	Vector of Albers x-coordinates to be projected to latitude/longitude.
y	Vector of Albers y-coordinates 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
