Coordinates Transformations – Point and UTM transformations for GeoKit.¶ ↑

With Coordinates Transformations you can transform GeoKit::LatLng and GeoKit::Bounds into point and utm coordinates.

The latest version of Coordinates Transformations can be installed with Rubygems:

% [sudo] gem install coordinates_transformations

Include the gem in your Gemfile:

gem 'coordinates_transformations'

Source code can be downloaded from Github:

A GeoKit::LatLng object has two new methods available: to_utm, and to_point

new_york = GeoKit::LatLng.new(40.714353, -74.005973)
new_york.to_utm
new_york.to_point

The UTM transformation returns a GeoUtm::UTM
The point transformation returns GeoRuby::SimpleFeatures::Point

A GeoKit::Bounds object has two new methods available: to_utm, and to_point

area = GeoKit::Bounds.from_point_and_radius(new_york, 20, {:units => :kms})
area.to_utm 
area.to_multipoint

The UTM transformation returns an array of GeoUtm::UTM [sw utm,ne utm]
The multipoint returns a GeoRuby::SimpleFeatures::MultiPoint
