Overview

A LocationItem can be used to store GPS related information, addresses etc.

This is useful for location awareness related functions

Examples:

Send point commands

Location << '30,20'   # latitude of 30, longitude of 20
Location << '30,20,80' # latitude of 30, longitude of 20, altitude of 80
Location << PointType.new('40,20')

Determine the distance between two locations

logger.info "Distance from Location 1 to Location 2: #{Location1.state - Location2.state}"
logger.info "Distance from Location 1 to Location 2: #{Location1.state - PointType.new('40,20')}"
