class LayoutTileSource[K] extends AnyRef

Reads tiles by key from a RasterSource as keyed by a LayoutDefinition

Note

It is required that the RasterSource is pixel aligned with the LayoutDefinition

Instance Constructors

  1. new LayoutTileSource(source: RasterSource, layout: LayoutDefinition, tileKeyTransform: (SpatialKey) ⇒ K)(implicit arg0: SpatialComponent[K])

    source

    raster source that can be queried by bounding box

    layout

    definition of a tile grid over the pixel grid

    tileKeyTransform

    defines the key transformation you want to apply to the spatially tiled data

  18. def rasterRegionForKey(key: K): Option[RasterRegion]
  19. def read(key: K, bands: Seq[Int]): Option[MultibandTile]

    Read tile according to key.

    Read tile according to key. If tile area intersects source partially the non-intersecting pixels will be filled with NODATA. If tile area does not intersect source None will be returned.

  20. def read(key: K): Option[MultibandTile]
  21. def readAll(): Iterator[(K, MultibandTile)]

    Read all available tiles

  22. def readAll(keys: Iterator[K]): Iterator[(K, MultibandTile)]
  23. def readAll(keys: Iterator[K], bands: Seq[Int]): Iterator[(K, MultibandTile)]

    Read multiple tiles according to key.

    Read multiple tiles according to key. If each tile area intersects source partially the non-intersecting pixels will be filled with NODATA. If tile area does not intersect source it will be excluded from result iterator.
