Amazon Redshift unterstützt UDFs ab Patch 198 nicht mehr die Erstellung von neuem Python. Das bestehende Python UDFs wird bis zum 30. Juni 2026 weiterhin funktionieren. Weitere Informationen finden Sie im [Blog-Posting](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/).

# Geofunktionen
<a name="geospatial-functions"></a>

Die Beziehungen zwischen Geometrieobjekten basieren auf dem Dimensionally Extended nine-Intersection Model (DE-9IM). Dieses Modell definiert Prädikate wie Equals, Contains und Covers. Weitere Informationen zur Definition von räumlichen -Beziehungen finden Sie unter [DE-9IM](https://en.wikipedia.org/wiki/DE-9IM) in Wikipedia.

Weitere Informationen zur Verwendung raumbezogener Daten mit Amazon Redshift finden Sie unter [Abfrage von Geodaten in Amazon Redshift](geospatial-overview.md).

Amazon Redshift bietet Geofunktionen für die Datentypen `GEOMETRY` und `GEOGRAPHY`. Im Folgenden sind die Funktionen aufgeführt, die den `GEOGRAPHY`-Datentyp unterstützen:
+ [ST\$1Area](ST_Area-function.md)
+ [ST\$1AsEWKT](ST_AsEWKT-function.md)
+ [ST\$1 JSON AsGeo](ST_AsGeoJSON-function.md)
+ [ST\$1 EWKB AsHex](ST_AsHexEWKB-function.md)
