miucs2latlon: Convert between UCS and geographical coordinates

In steingod/R-mipolsat: Useful functions for handling locally processed satellite data

Description

Coordinates within the Cartesian User Coordinate System, northings and eastings are converted to geographical latitude and longitude using a spherical Earth and an Earth radius of 6371. km. This is a very crude approximation, for better accuracy and support of other Earth models use e.g. PROJ.4 software (http://www.remotesensing.org/proj).

Usage

miucs2latlon(northings, eastings)  

Arguments

northings	distance to the line through the North Pole and -180 - 180 degrees longitude in kilometers, negative southwards in the Atlantic
eastings	distance from the Greenwich meridian in kilometers, positive eastwards

Value

Returns a data.frame with latitude (lat) and longitude (lon) and metadata.
