関数: inverseOrthoProjection()

inverseOrthoProjection(interestPoint, origin): GeoCoord

定義: projection.ts:176

Converts an orthographic projection point back to geographic coordinates.

パラメータ

interestPoint

Point

The point in orthographic projection (in meters)

origin

GeoCoord

The center point of the hemisphere (must match the forward projection)

戻り値

GeoCoord

The geographic coordinate

Remarks

This is the inverse of orthoProjection. Given a point in orthographic projection space (in meters), it returns the corresponding latitude/longitude.

例

const origin = { latitude: 45.0, longitude: 0.0 };
const point = { x: 100000, y: 200000 }; // Some point in projection space
const coord = inverseOrthoProjection(point, origin);
console.log(coord); // { latitude: ..., longitude: ... }
