Type Members

1. trait Boundable[K] extends Serializable

   

   This type class marks K as point that can be bounded in space.

   This type class marks K as point that can be bounded in space. It is used to construct bounding hypercube for a set of Ks.

   The bounds must be calculated by taking min/max of each component dimension of K. Consequently the result may be neither a nor b, but a new value.

2. sealed trait Bounds[+A] extends Product with Serializable

   

   Represents a region of discrete space, bounding it by minimum and maximum points.

   Represents a region of discrete space, bounding it by minimum and maximum points. The bounds maybe EmptyBounds as result of intersection operation.

   The dimensionality of region is implied by the dimensionality of type parameter A. Boundable typeclass is required to manipulate instance of A.

   Conceptually this ADT is similar Option[KeyBounds[A]] but adds methods convenient for testing and forming region intersection, union and mutation.

   A

   Type of keys, or points in descrete space

3. implicit final class CRSWorldExtent extends AnyVal

   

4. abstract class CellGridLayoutCollectionMethods[K, V <: CellGrid[Int], M] extends MethodExtensions[Seq[(K, V)] with Metadata[M]]

   

5. class ContextCollection[K, V, M] extends Seq[(K, V)] with Metadata[M]

   

6. class FloatingLayoutScheme extends LayoutScheme

   

7. implicit class GeoTiffInfoMethods extends AnyRef

   

8. case class GlobalLayout(tileSize: Int, zoom: Int, threshold: Double) extends LayoutType with Product with Serializable

9. trait Implicits extends layer.merge.Implicits with layer.buffer.Implicits with CrsFormats with layer.stitch.Implicits with layer.mapalgebra.Implicits with layer.mapalgebra.focal.Implicits with layer.mapalgebra.focal.hillshade.Implicits with layer.mapalgebra.local.Implicits with layer.mapalgebra.local.temporal.Implicits with layer.mask.Implicits

   

10. case class KeyBounds[+K](minKey: K, maxKey: K) extends Bounds[K] with Product with Serializable

    

    Represents non-empty region of descrete space.

    Represents non-empty region of descrete space. Any key which is greater than or equal to minKey and less then or equal to maxKey in each individual dimension is part of the region described by these Bounds.

    minKey

    Minimum key of the region, inclusive.

    maxKey

    Maximum key of the region, inclusive.

11. trait KeyExtractor[K] extends Serializable

    

12. case class LayoutDefinition(extent: Extent, tileLayout: TileLayout) extends GridExtent[Long] with Product with Serializable

    

    Defines tiled raster layout

    Defines tiled raster layout

    extent

    extent covered by the layout tiles, could be greater than extent of data in the layer

    tileLayout

    tile layout (tile cols, tile rows, tile pixel size)

13. case class LayoutLevel(zoom: Int, layout: LayoutDefinition) extends Product with Serializable

    

14. trait LayoutScheme extends Serializable

    

    A LayoutScheme is something that provides LayoutLevels based on an integer id or an extent and cellsize.

    A LayoutScheme is something that provides LayoutLevels based on an integer id or an extent and cellsize. The resolution of the tiles for the LayoutLevel returned will not necessarily match the CellSize provided, but an appropriately close selection will be made.

    It also provides methods for next zoomed out tile layout level.

15. class LayoutTileSource[K] extends AnyRef

    

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

    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

16. sealed trait LayoutType extends AnyRef

    

    Strategy for selecting LayoutScheme before metadata is collected

17. case class LocalLayout(tileCols: Int, tileRows: Int) extends LayoutType with Product with Serializable

    geotrellis.layer.FloatingLayoutScheme

18. class LocalLayoutScheme extends LayoutScheme

    

    Layout scheme for building a local power of 2 pyramid.

    Layout scheme for building a local power of 2 pyramid. Zooming out will reduce raster pixel resolution by 2, while using minimum number of tiles. Layouts produced by this scheme will not be power of 2 however. Uneven layouts will pyramid up until they are reduced to a single tile.

19. class MapKeyTransform extends Serializable

    

    Transforms between geographic map coordinates and spatial keys.

    Transforms between geographic map coordinates and spatial keys. Since geographic point can only be mapped to a grid tile that contains that point, transformation from Extent to GridBounds to Extent will likely not produce the original geographic extent, but a larger one.

20. trait Metadata[M] extends AnyRef

    

21. type MultibandRasterCollection[M] = Seq[Raster[MultibandTile]] with Metadata[M]

    

22. type MultibandTileLayerCollection[K] = Seq[(K, MultibandTile)] with Metadata[TileLayerMetadata[K]]

24. case class SpaceTimeKey(col: Int, row: Int, instant: Long) extends Product with Serializable

    

25. type SpatialComponent[K] = Component[K, SpatialKey]

    

26. case class SpatialKey(col: Int, row: Int) extends Product2[Int, Int] with Product with Serializable

    

    A SpatialKey designates the spatial positioning of a layer's tile.

27. type TemporalComponent[K] = Component[K, TemporalKey]

    

28. case class TemporalKey(instant: Long) extends Product with Serializable

    

    A TemporalKey designates the temporal positioning of a layer's tile.

29. trait TemporalKeyExtractor extends KeyExtractor[SpaceTimeKey]
