meos.js / TGeomPoint

Class: TGeomPoint

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:100

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();

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:189

WKT string representation.

Parameters

string

Overrides

Temporal.toString

toTGeometry()

toTGeometry(): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:316

Parameters

unaryUnion?

boolean = false

Returns

string

transform()

transform(srid): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:298

Reprojects to the given SRID. MEOS: tspatial_transform

Parameters

srid

number

Returns

TGeomPoint

transformPipeline()

transformPipeline(
   pipelinestr, 
   srid, 
   isForward?): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:306

Reprojects using a PROJ pipeline string. MEOS: tspatial_transform_pipeline

Parameters

pipelinestr

string

srid

number

isForward?

boolean = true

Returns

TGeomPoint

valueAtTimestamp()

valueAtTimestamp(t): string | null;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:256

Evaluates the temporal geometry at a specific timestamp. Returns the WKT string or null if outside the domain. MEOS: temporal_at_timestamptz + tgeo_start_value + geo_as_text

Parameters

t

number

Returns

string | null

valueN()

valueN(n): string | null;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:243

Returns the n-th distinct geometry value (0-based) as a WKT string. MEOS: tgeo_value_n + geo_as_text

Parameters

n

number

Returns

string | null

fromBaseTemporal()

static fromBaseTemporal(wkt, domain): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:143

Create a TGeomPoint with constant geometry wkt spanning the same domain as domain. MEOS: tpoint_from_base_temp

Parameters

wkt

string

domain

TGeomPoint

Returns

TGeomPoint

fromBaseTime()

static fromBaseTime(
   wkt, 
   time, 
   type, 
   interp?): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:154

Create a TGeomPoint with constant geometry wkt over a time object. MEOS: tpointseq_from_base_tstzset / tstzspan / tpointseqset_from_base_tstzspanset

Parameters

wkt

string

time

number

type

"tstzset" | "tstzspan" | "tstzspanset"

interp?

number = 3

Returns

TGeomPoint

fromInstant()

static fromInstant(wkt, timestamp): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:132

Create a TGeomPointInst from a WKT point string and a timestamp.

Parameters

wkt

string

WKT geometry string (e.g. "POINT(1 2)").

timestamp

number

Microseconds since 2000-01-01 UTC. MEOS: tpointinst_make

Returns

TGeomPoint

fromMFJSON()

static fromMFJSON(mfjson): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:121

Parse a TGeomPoint from a MF-JSON string. MEOS: tgeompoint_from_mfjson

Parameters

mfjson

string

Returns

TGeomPoint

fromString()

static fromString(wkt): TGeomPoint;

Defined in: core/types/basic/tgeompoint/TGeomPoint.ts:113

Parse a TGeomPoint from a WKT/EWKT string. MEOS: tgeompoint_in

Parameters
