RasterSourceRelation

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.
