func Parse 

func Parse(data string, opts *ParseOptions) (Object, error)

Parse a GeoJSON object

type ParseOptions 

type ParseOptions struct {
	// IndexChildren option will cause the object to index their children
	// objects when the number of children is greater than or equal to the
	// provided value. Setting this value to 0 will disable indexing.
	// The default is 64.
	IndexChildren int
	// IndexGeometry option will cause the object to index it's geometry
	// when the number of points in it's base polygon or linestring is greater
	// that or equal to the provided value. Setting this value to 0 will
	// disable indexing.
	// The default is 64.
	IndexGeometry int
	// IndexGeometryKind is the kind of index implementation.
	// Default is QuadTreeCompressed
	IndexGeometryKind geometry.IndexKind
	// RequireValid option cause parse to fail when a geojson object is invalid.
	RequireValid bool
	// AllowSimplePoints options will force to parse to return the SimplePoint
	// type when a geojson point only consists of an 2D x/y coord and no extra
	// json members.
	AllowSimplePoints bool
