readToGeometryRDD

public static SpatialRDD<org.locationtech.jts.geom.Geometry> readToGeometryRDD(org.apache.spark.api.java.JavaSparkContext sc,
                                                                               String inputPath,
                                                                               int wktColumn,
                                                                               boolean allowInvalidGeometries,
                                                                               boolean skipSyntacticallyInvalidGeometries)

Read a SpatialRDD from a file.

Parameters:

sc -

inputPath -

wktColumn - The column which contains the wkt string. Start from 0.

allowInvalidGeometries - whether allows topology-invalid geometries exist in the generated RDD

skipSyntacticallyInvalidGeometries - whether allows Sedona to automatically skip syntax-invalid geometries, rather than throw errors

Returns:

readToGeometryRDD

public static SpatialRDD<org.locationtech.jts.geom.Geometry> readToGeometryRDD(org.apache.spark.api.java.JavaRDD rawTextRDD,
                                                                               int wktColumn,
                                                                               boolean allowInvalidGeometries,
                                                                               boolean skipSyntacticallyInvalidGeometries)

Read a SpatialRDD from a string type rdd.

Parameters:

rawTextRDD - a string type RDD

wktColumn - The column which contains the wkt string. Start from 0.

allowInvalidGeometries - whether allows topology-invalid geometries exist in the generated RDD

skipSyntacticallyInvalidGeometries - whether allows Sedona to automatically skip syntax-invalid geometries, rather than throw errors

Returns:
