rgeo-geojson

Gem Version Build Status

rgeo-geojson is an extension to RGeo that provides GeoJSON encoding and decoding.

Summary

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

Install

RGeo::GeoJSON requires:

  • Ruby 2.1.0 or later
