Parses an Extended Well-Known Text (EWKT) description of a geometry and returns the corresponding Geometry value. The returned SRID is the SRID in the EWKT if specified, or 0 otherwise.
For the corresponding Databricks SQL function, see st_geomfromewkt function.
Syntax
from pyspark.databricks.sql import functions as dbf
dbf.st_geomfromewkt(col=<col>)
Parameters
| Parameter | Type | Description |
|---|---|---|
col |
pyspark.sql.Column or str |
A string value, representing a geometry in Extended WKT (EWKT) format. |
Notes
The SRID is the SRID in the EWKT if specified, or 0 otherwise.
The function returns None if the input is None.
Examples
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('POINT Z (1 2 3)',)], ['ewkt'])
df.select(dbf.st_srid(dbf.st_geomfromewkt('ewkt')).alias('result')).collect()
[Row(result=0)]
from pyspark.databricks.sql import functions as dbf
df = spark.createDataFrame([('SRID=3857;POINT Z (1 2 3)',)], ['ewkt'])
df.select(dbf.st_asewkt(dbf.st_geomfromewkt('ewkt')).alias('result')).collect()
[Row(result='SRID=3857;POINT Z (1 2 3)')]
