rgeo-geojson
is an extension to RGeo
that provides GeoJSON encoding and decoding.
RGeo is a key component for writing location-aware applications in the Ruby programming language. At its core is an implementation of the industry standard OGC Simple Features Specification, which provides data representations of geometric objects such as points, lines, and polygons, along with a set of geometric analysis operations. See the README for the "rgeo" gem for more information.
RGeo::GeoJSON
is an optional RGeo module that provides GeoJSON encoding
and decoding. GeoJSON is a JSON format used for
geographic data structures.
Example:
require 'rgeo/geo_json'
str1 = '{"type":"Point","coordinates":[1,2]}'
geom = RGeo::GeoJSON.decode(str1)
geom.as_text # => "POINT (1.0 2.0)"
str2 = '{"type":"Feature","geometry":{"type":"Point","coordinates":[2.5,4.0]},"properties":{"color":"red"}}'
feature = RGeo::GeoJSON.decode(str2)
feature['color'] # => 'red'
feature.geometry.as_text # => "POINT (2.5 4.0)"
hash = RGeo::GeoJSON.encode(feature)
hash.to_json == str2 # => true
RGeo::GeoJSON
requires:
- Ruby 2.1.0 or later
- rgeo 1.0.0 or later
Include in your bundle:
gem 'rgeo-geojson'
Install rgeo-geojson
as a gem:
gem install rgeo-geojson
See the README for the rgeo
gem, a required dependency, for further installation information.
