UpsProjection

open class UpsProjection(var isNorth: Boolean = true) : Abstract2DProjection

Represents a Universal Polar Stereographic geographic projection.

Parameters

isNorth

true for the north aspect, false for the south aspect.

Constructors

constructor(isNorth: Boolean = true)

Types

object Companion

Properties

open override val displayName: String

This projection's display name.

override val is2D: Boolean = true

Indicates whether this projection is a 2D projection.

open val isContinuous: Boolean

Indicates whether this projection is continuous with itself horizontally.

var isNorth: Boolean

Indicates whether this projection is the north or south aspect.

projectionLimits

open override val projectionLimits: Sector

Indicates the geographic limits of this projection. May be null to indicate the full range of latitude and longitude.

Functions

cartesianToGeographic

open override fun cartesianToGeographic(ellipsoid: Ellipsoid, x: Double, y: Double, z: Double, offset: Double, result: Position): Position

Converts a Cartesian point to a geographic position.

cartesianToLocalTransform

open override fun cartesianToLocalTransform(ellipsoid: Ellipsoid, x: Double, y: Double, z: Double, result: Matrix4): Matrix4

geographicToCartesian

open override fun geographicToCartesian(ellipsoid: Ellipsoid, latitude: Angle, longitude: Angle, altitude: Double, offset: Double, result: Vec3): Vec3

Converts a geographic position to Cartesian coordinates.

geographicToCartesianBorder

open override fun geographicToCartesianBorder(ellipsoid: Ellipsoid, sector: Sector, numLat: Int, numLon: Int, height: Float, origin: Vec3?, offset: Double, result: FloatArray): FloatArray

geographicToCartesianGrid

open override fun geographicToCartesianGrid(ellipsoid: Ellipsoid, sector: Sector, numLat: Int, numLon: Int, height: FloatArray?, verticalExaggeration: Double, origin: Vec3?, offset: Double, result: FloatArray, rowOffset: Int, rowStride: Int): FloatArray

geographicToCartesianNormal

open override fun geographicToCartesianNormal(ellipsoid: Ellipsoid, latitude: Angle, longitude: Angle, result: Vec3): Vec3

geographicToCartesianTransform

open override fun geographicToCartesianTransform(ellipsoid: Ellipsoid, latitude: Angle, longitude: Angle, altitude: Double, result: Matrix4): Matrix4

open override fun intersect(ellipsoid: Ellipsoid, line: Line, result: Vec3): Boolean
