meos.js / TGeogPoint

Class: TGeogPoint

Defined in: core/types/basic/tgeogpoint/TGeogPoint.ts:98

Temporal geography point type.

Like TGeomPoint but uses geodetic (WGS-84 or other ellipsoidal) coordinates. Distance and area functions operate on the sphere/spheroid rather than on a flat plane.

Geometry values are exchanged as WKT strings at the JS boundary.

Example

await initMeos();
const t = TGeogPoint.fromString('[POINT(2.35 48.85)@2001-01-01, POINT(2.29 48.86)@2001-01-02]');
console.log(t.startValue()); // POINT(2.35 48.85)
console.log(t.length());     // geodetic distance in metres
t.free();
