st_touches

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.

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)]
