In geo: Draw and Annotate Maps, Especially Charts of the North Atlantic

Description

Inverse Lambert projection.

Usage

invlambert(x, y, lat0, lon0, lat1, scale = "km", old = F)

Arguments

x, y	The input data to be inversely projected as two vectors
lat0	First latitude defining of the projection
lon0	Longitude defining the projection
lat1	Second latitude defining the projection
scale	Scale of the input data, "km" default, redundant ??
old	Old method, seldom used???

Value

List of components:

lat, lon	Coordinates in latitude and longitude
x, y	Input coordinates (projected)
scale	Scale
projection	Projection (stated redunantly)
lat0, lon0, lat1	Defining lats and lon

is returned invisibly.

Note

Needs elaboration and perhaps documenting with lambert in the same doc-file.
