type Bounds ¶

type Bounds struct {
	Min, Max Point
}

func NewBounds() Bounds

func NewBoundsPoint(point Point) Bounds

func (b Bounds) Copy() Bounds

func (b Bounds) Empty() bool

func (b Bounds) ExtendPoint(point Point) Bounds

func (b Bounds) ExtendPoints(points []Point) Bounds

func (b Bounds) ExtendPointss(pointss Polygon) Bounds

func (b Bounds) IsZero() bool

func (b1 Bounds) Overlaps(b2 Bounds) bool

type Feature ¶

type Feature struct {
	T
	Properties interface{}
}

Create a Feature to serialize GeoJSON with additional arbitrary properties. Properties may be any JSON-serializable value. Encoding a Feature to another format, like WKT, will only encode the geometry, not the properties.

func NewFeature(t T, properties interface{}) Feature

type FeatureCollection ¶

type FeatureCollection struct {
	Features   []T
	Properties interface{}
}

func (f FeatureCollection) AppendFeature(newFeature Feature) FeatureCollection

func (f FeatureCollection) AppendGeometry(t T, properties interface{}) FeatureCollection

func (f FeatureCollection) Bounds(b Bounds) Bounds

type GeometryCollection ¶

type GeometryCollection []T

func (geometryCollection GeometryCollection) Bounds(b Bounds) Bounds

type LineString ¶

type LineString []Point

func (lineString LineString) Bounds(b Bounds) Bounds

type MultiLineString ¶

type MultiLineString []LineString

func (multiLineString MultiLineString) Bounds(b Bounds) Bounds

type MultiPoint ¶

type MultiPoint []Point

func (multiPoint MultiPoint) Bounds(b Bounds) Bounds

type MultiPolygon ¶

type MultiPolygon []Polygon

func (multiPolygon MultiPolygon) Bounds(b Bounds) Bounds

type Point ¶

type Point []float64

The first two components of Point are X and Y. You may use as many additional components as you like for Z, M, etc. They are ignored, but preserved for GeoJSON encoding.

func New2Point(x, y float64) Point

func NewNPoint(s ...float64) Point

func (point Point) Bounds(b Bounds) Bounds

func (point Point) Equal(other Point) bool

type Polygon ¶

type Polygon []Ring

func (polygon Polygon) Bounds(b Bounds) Bounds

type Ring ¶

type Ring []Point

type T ¶

type T interface {
	Bounds(Bounds) Bounds
}
