ui/map/shapes/shapeGeometry¶

Interfaces¶

GeoPoint¶

Defined in: ui/map/shapes/shapeGeometry.ts:9

A geographic point in {lat, lng} form (BaseDrawingManager's DrawingPoint).

Properties¶

lat¶

lat: number;

Defined in: ui/map/shapes/shapeGeometry.ts:10

lng¶

lng: number;

Defined in: ui/map/shapes/shapeGeometry.ts:11

Variables¶

CIRCLE_PREVIEW_SEGMENTS¶

const CIRCLE_PREVIEW_SEGMENTS: 72 = 72;

Defined in: ui/map/shapes/shapeGeometry.ts:22

Number of segments used to preview a circle as a polygon ring. Matches the backend's CIRCLE tessellation (proxy/handlers/shapes.py) so the preview looks like what the server will render back.

Functions¶

distanceNm()¶

function distanceNm(a, b): number;

Defined in: ui/map/shapes/shapeGeometry.ts:25

Great-circle (haversine) distance between two points in nautical miles.

Parameters¶

a¶

GeoPoint

b¶

GeoPoint

Returns¶

number

boxCornerPoints()¶

function boxCornerPoints(a, b): GeoPoint[];

Defined in: ui/map/shapes/shapeGeometry.ts:40

Expand two opposite corners of an axis-aligned box (BlueSky BOX semantics) into its four corners, in ring order.

Parameters¶

a¶

GeoPoint

b¶

GeoPoint

Returns¶

GeoPoint[]

circleRingPoints()¶

function circleRingPoints(
   center, 
   radiusNm, 
   segments?): GeoPoint[];

Defined in: ui/map/shapes/shapeGeometry.ts:54

Tessellate a circle (centre + radius in nautical miles) into a polygon ring using the same equirectangular approximation as the backend's CIRCLE-to-POLY conversion, so the preview matches the rendered result.

Parameters¶

center¶

GeoPoint

radiusNm¶

number

segments?¶

number = CIRCLE_PREVIEW_SEGMENTS

Returns¶

GeoPoint[]
