class GeoTrellisRasterSource extends RasterSource

Note: GeoTrellis AttributeStore does not store the band count for the layers by default, thus they need to be provided from application configuration.

  56. lazy val 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.
