latlon2ucs: Convert between geographical and UCS coordinates

In steingod/R-osisaf: Useful functions for handling EUMETSAT Ocean and Sea Ice SAF data

Description

Geographical coordinates (latitude and longitude) are converted to coordinates within the Cartesian User Coordinate System, northings and eastings 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

latlon2ucs(latitude, longitude)  

Arguments

latitude	decimal degrees, positive in northern hemisphere
longitude	decimal degrees, positive Eastwards, negative westwards

Value

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