raster

Type Members

1. implicit class DataFrameReaderHasRasterSourceFormat extends AnyRef

   

   Adds raster format specifier to DataFrameReader.

2. type RasterSourceDataFrameReader = DataFrameReader with Tagged[RasterSourceDataFrameReaderTag]

   

3. implicit class RasterSourceDataFrameReaderHasOptions extends CatalogReaderOptionsSupport[RasterSourceDataFrameReaderTag] with SpatialIndexOptionsSupport[RasterSourceDataFrameReaderTag]

   

   Adds option methods relevant to RasterSourceDataSource.

4. trait RasterSourceDataFrameReaderTag extends AnyRef

   

5. class RasterSourceDataSource extends DataSourceRegister with RelationProvider

   

6. case class RasterSourceRelation(sqlContext: SQLContext, catalogTable: RasterSourceCatalogRef, bandIndexes: Seq[Int], subtileDims: Option[Dimensions[Int]], lazyTiles: Boolean, spatialIndexPartitions: Option[Int]) extends BaseRelation with TableScan with Product with Serializable

   

   Constructs a Spark Relation over one or more RasterSource paths.

   Constructs a Spark Relation over one or more RasterSource paths.

   sqlContext

   Query context

   catalogTable

   Specification of raster path sources

   bandIndexes

   band indexes to fetch

   subtileDims

   how big to tile/subdivide rasters info

   lazyTiles

   if true, creates a lazy representation of tile instead of fetching contents.

   spatialIndexPartitions

   Number of spatial index-based partitions to create. If Option value > 0, that number of partitions are created after adding a spatial index. If Option value <= 0, uses the value of numShufflePartitions in SparkContext. If None, no spatial index is added and hash partitioning is used.
