Abstract Value Members

  1. abstract def attributes: Map[String, String]

    Return the "base" metadata, usually it is a zero band metadata, a metadata that is valid for the entire source and for the zero band

  2. abstract def attributesForBand(band: Int): Map[String, String]

    Return a per band metadata

  3. abstract def bandCount: Int
  4. abstract def cellType: CellType
  5. abstract def crs: CRS
  6. abstract def gridExtent: GridExtent[Long]
  7. abstract def name: SourceName

    Source name, that can be a path or any name that is associated with Raster

  8. abstract def resolutions: List[CellSize]

    All available overview resolutions for this raster source

    All available overview resolutions for this raster source

    • For base RasterSource instance this will be resolutions of available overviews including the base resolution.
    • For reprojected RasterSource these resolutions represent an estimate where each cell in target CRS has approximately the same geographic coverage as a cell in the source CRS.

    For compatibility with OverviewStrategy, this list should be sorted from the most resolute cell size to the least resolute cell size, as determined by _.resolution.

    When reading raster data the underlying implementation will have to sample from one of these resolutions. It is possible that a read request for a small bounding box will results in significant IO request when the target cell size is much larger than closest available resolution.

Concrete Value Members

  1. def cellSize: CellSize

    Cell size at which rasters will be read when using this RasterSource

    Cell size at which rasters will be read when using this RasterSource

    Note: some re-sampling of underlying raster data may be required to produce this cell size.

  2. def cols: Long

    Raster pixel column count

  3. def extent: Extent
  4. def rows: Long

    Raster pixel row count
