The following are the common standard SRIDs that we support.

Types

type BoundingBox 

type BoundingBox struct {
	LoX float64 `protobuf:"fixed64,1,opt,name=lo_x,json=loX,proto3" json:"lo_x,omitempty"`
	HiX float64 `protobuf:"fixed64,2,opt,name=hi_x,json=hiX,proto3" json:"hi_x,omitempty"`
	LoY float64 `protobuf:"fixed64,3,opt,name=lo_y,json=loY,proto3" json:"lo_y,omitempty"`
	HiY float64 `protobuf:"fixed64,4,opt,name=hi_y,json=hiY,proto3" json:"hi_y,omitempty"`
}

BoundingBox represents the bounding box of a Geospatial type. Note the lo coordinates can be higher in value than the hi coordinates for spherical geometries. NOTE: Do not use these to compare bounding boxes. Use the library functions provided in the geo package to perform these calculations.

type EWKB 

type EWKB []byte

EWKB is the Extended Well Known Bytes form of a spatial object.

type EWKT 

type EWKT string

EWKT is the Extended Well Known Text form of a spatial object.

type SRID 

type SRID int32

SRID is a Spatial Reference Identifer. All geometry and geography shapes are stored and represented as using coordinates that are bare floats. SRIDs tie these floats to the planar or spherical coordinate system, allowing them to be interpreted and compared.

The zero value is special and means an unknown coordinate system.

type ShapeType 

type ShapeType int32

ShapeType is the type of a spatial shape. Each of these corresponds to a different representation and serialization format. For example, a Point is a pair of doubles (or more than that for geometries with Z or N), a LineString is an ordered series of Points, etc. 

const (
	ShapeType_Unset           ShapeType = 0
	ShapeType_Point           ShapeType = 1
	ShapeType_LineString      ShapeType = 2
	ShapeType_Polygon         ShapeType = 3
	ShapeType_MultiPoint      ShapeType = 4
	ShapeType_MultiLineString ShapeType = 5
	ShapeType_MultiPolygon    ShapeType = 6
	// Geometry can contain any type.
	ShapeType_Geometry ShapeType = 7
	// GeometryCollection can contain a list of any above type except for Geometry.
	ShapeType_GeometryCollection ShapeType = 8
)

func (ShapeType) EnumDescriptor 

func (ShapeType) EnumDescriptor() ([]byte, []int)

func (ShapeType) MultiType 

func (s ShapeType) MultiType() ShapeType

MultiType returns the corresponding multi-type for a shape type, or unset if there is no multi-type.

func (ShapeType) String 

func (x ShapeType) String() string

type SpatialObject

	// Type is the type of the SpatialObject.
	Type SpatialObjectType `protobuf:"varint,1,opt,name=type,proto3,enum=cockroach.geopb.SpatialObjectType" json:"type,omitempty"`
	// EWKB is the EWKB representation of the spatial object.

	// SRID is the denormalized SRID derived from the EWKB.
	SRID SRID `protobuf:"varint,3,opt,name=srid,proto3,casttype=SRID" json:"srid,omitempty"`
	// ShapeType is denormalized ShapeType derived from the EWKB.
	ShapeType ShapeType `protobuf:"varint,4,opt,name=shape_type,json=shapeType,proto3,enum=cockroach.geopb.ShapeType" json:"shape_type,omitempty"`
	// BoundingBox is the bounding box of the SpatialObject.
	BoundingBox *BoundingBox `protobuf:"bytes,5,opt,name=bounding_box,json=boundingBox,proto3" json:"bounding_box,omitempty"`
