GeoTrellisResampleRasterSource

class GeoTrellisResampleRasterSource extends RasterSource

RasterSource that resamples on read from underlying GeoTrellis layer.

Note: The constructor is unfriendly. This class is not intended to constructed directly by the users. Refer to GeoTrellisRasterSource for example of correct setup. It is expected that the caller has significant pre-computed information about the layers.

  55. lazy val resolutions: List[CellSize]

    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.
