Returns True if the two geometries touch each other. Geometry collections are not supported.

For the corresponding Databricks SQL function, see st_touches function.

Syntax

Python
from pyspark.databricks.sql import functions as dbf

dbf.st_touches(col1=<col1>, col2=<col2>)

Parameters

Parameter

Type

Description

col1

pyspark.sql.Column or str

The first Geometry value.

col2

pyspark.sql.Column or str

The second Geometry value.

Notes

The two geometries are expected to have the same SRID value, otherwise an error is returned.

Examples

Python
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('LINESTRING(5 0,5 10)','MULTILINESTRING((0 0,10 10),(0 10,10 0))',)], ['wkt1', 'wkt2'])
df.select(dbf.st_touches(dbf.st_geomfromtext('wkt1'), dbf.st_geomfromtext('wkt2')).alias('result')).collect()
Output
[Row(result=False)]
