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. This makes it ideal for modeling geolocation data. It also supports a suite of optional add-on modules that provide various geolocation-related services.
Use the core rgeo gem to:
- Represent spatial and geolocation data objects such as points, lines, and polygons in your Ruby application.
- Perform standard spatial analysis operations such as finding intersections, creating buffers, and computing lengths and areas.
- Correctly handle spherical geometry, and compute geographic projections for map display and data analysis.
- Read and write location data in the WKT and WKB representations used by spatial databases.
RGeo forms the core of a suite of tools, including:
- Generate and interpret GeoJSON data for communication with common location-based web services using the rgeo-geojson gem.
- Read GIS datasets from ESRI shapefiles using the rgeo-shapefile gem.
- Extend ActiveRecord to support spatial databases using RGeo's spatial ActiveRecord adapters. These are available via the gems:
- activerecord-postgis-adapter for PostGIS
- activerecord-spatialite-adapter for Spatialite
- activerecord-mysql2spatial-adapter for MySQL Spatial
- and more to come...
