Type Members

1.  case class CRSMetaData() extends Product with Serializable

   A case class that holds CRS metadata for geometry columns.

   A case class that holds CRS metadata for geometry columns. This class is left empty since CRS metadata was not implemented yet.

2.  trait GeoParquetFileFormatBase extends FileFormat with DataSourceRegister

   Trait of GeoParquetFileFormat defines a method for spatial predicate push down.

   Trait of GeoParquetFileFormat defines a method for spatial predicate push down. The actual implementations of GeoParquetFileFormat are in the sql/spark-3.x submodule for specific Spark minor versions.

3.  case class GeoParquetMetaData(version: Option[String], primaryColumn: String, columns: Map[String, GeometryFieldMetaData]) extends Product with Serializable

   A case class that holds the metadata of GeoParquet file

   A case class that holds the metadata of GeoParquet file

   version

   The version identifier for the GeoParquet specification.

   primaryColumn

   The name of the "primary" geometry column.

   columns

   Metadata about geometry columns.

4.  trait GeoParquetSpatialFilter extends AnyRef

   Filters containing spatial predicates such as ST_Within(geom, ST_GeomFromText(...)) will be converted to GeoParquetSpatialFilter and get pushed down to GeoParquetFileFormat by org.apache.spark.sql.sedona_sql.optimization.SpatialFilterPushDownForGeoParquet.

5.  case class GeometryFieldMetaData(encoding: String, geometryTypes: Seq[String], bbox: Seq[Double], crs: Option[CRSMetaData] = None) extends Product with Serializable

   A case class that holds the metadata of geometry column in GeoParquet metadata

   A case class that holds the metadata of geometry column in GeoParquet metadata

   encoding

   Name of the geometry encoding format. Currently only "WKB" is supported

   geometryTypes

   The geometry types of all geometries, or an empty array if they are not known.

   bbox

   Bounding Box of the geometries in the file, formatted according to RFC 7946, section 5.
