go-whosonfirst-spatial-rtree

In-memory implementation of the go-whosonfirst-spatial interfaces.

Important

This is work in progress. Documentation remains incomplete.

Interfaces

This package implements the following go-whosonfirst-spatial interfaces.

spatial.SpatialDatabase

import (
	"github.com/whosonfirst/go-whosonfirst-spatial/database"
	_ "github.com/whosonfirst/go-whosonfirst-spatial-rtree"       
)

db, err := database.NewSpatialDatabase(ctx, "rtree://")

Database URIs

The go-whosonfirst-spatial-rtree package is instantiated using a URI in the form of:

rtree://?{PARAMETERS}

Valid parameters include:
