meos.js / TGeomPoint

Class: TGeomPoint

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:101

Temporal geometry point type.

Wraps a MEOS TGeomPoint pointer. Geometry values are exchanged as WKT strings at the JS boundary; GSERIALIZED pointers never leak out of this class.

Supports all three subtypes (Instant, Sequence, SequenceSet). Linear interpolation is the default for sequences.

Example

await initMeos();
const t = TGeomPoint.fromString('[POINT(1 1)@2001-01-01, POINT(2 2)@2001-01-02]');
console.log(t.startValue()); // POINT(1 1)
console.log(t.length());     // ~157249.59...
t.free();
