Examples

const pt = point([ 1.1234, 1.9876, 10 ]);
const wkt1 = toWKT(pt); // 'POINT Z (1.1234 1.9876 10)'
const wkt2 = toWKT(pt, { dim: 2 }); // 'POINT (1.1234 1.9876)'
const wkt3 = toWKT(pt, { precision: 2 }); // 'POINT Z (1.12 1.99 10)'

const pt = point([ 1.1234, 1.9876, 10 ]); const wkt1 = toWKT(pt); // 'POINT Z (1.1234 1.9876 10)' const wkt2 = toWKT(pt, { dim: 2 }); // 'POINT (1.1234 1.9876)' const wkt3 = toWKT(pt, { precision: 2 }); // 'POINT Z (1.12 1.99 10)'
