Simple Features
Simple Features is a pure Go Implementation of the OpenGIS Simple Feature Access Specification (which can be found here).
The specification describes a common access and storage model for 2-dimensional geometries. This is the same access and storage model used by libraries such as GEOS, JTS, and PostGIS.
Simple Features also provides spatial analysis algorithms that operate on 2-dimensional geometries.

Library Features (native Go)
-
Marshalling/unmarshalling (WKT, WKB, GeoJSON).
-
3D and Measure coordinates.
-
Spatial analysis (geometry validation, boundary calculation, envelopes, convex hull, equality, is simple, intersects, length, closed, ring, area, centroid, point on surface).
-
Geometry manipulation (reverse, pointwise transform, force coordinates types).
GEOS Wrapper
A GEOS CGO wrapper is also provided, giving access to functionality not yet implemented natively in Go. The wrapper is implemented in a separate package, meaning that library users who don't need this additional functionality don't need to expose themselves to CGO.
