class GridExtent[N] extends GridIntegral[N]

Represents an abstract grid over geographic extent. Critically while the number of cell rows and columns is implied by the constructor arguments, they are intentionally not expressed to avoid Int overflow for large grids.

The constructor will throw java.lang.IllegalArgumentException if the provided extent and cell size do not match the provided cols and rows (dimensions).

  14. def createAlignedGridExtent(targetExtent: Extent, alignmentPoint: Point): GridExtent[N]

    Returns a GridExtent that with this grid's resolution.

    Returns a GridExtent that with this grid's resolution.

    This function will generate an extent that lines up with a grid having an origin at the given point and grid cells of the size given by the cellSize of the GridExtent. The resulting GridExtent, in general, will not be equal to targetExtent, but will have the smallest extent that lines up with the grid and also covers targetExtent.

  15. def createAlignedGridExtent(targetExtent: Extent): GridExtent[N]

    Returns a GridExtent that lines up with this grid's resolution and grid layout.

    Returns a GridExtent that lines up with this grid's resolution and grid layout.

    This function will generate an extent that lines up with the grid indicated by the GridExtent, having an origin at the upper-left corner of the extent, and grid cells having the size given by cellSize. The resulting GridExtent, in general, will not be equal to targetExtent, but will have the smallest extent that lines up with the grid and also covers targetExtent.

  16. def createAlignedRasterExtent(targetExtent: Extent): RasterExtent

    Returns a geotrellis.raster.RasterExtent that lines up with this RasterExtent's resolution, and grid layout.

    Returns a geotrellis.raster.RasterExtent that lines up with this RasterExtent's resolution, and grid layout.

    For example, the resulting RasterExtent will not have the given extent, but will have the smallest extent such that the whole of the given extent is covered, that lines up with the grid.

    Gets the Extent that matches the grid bounds passed in, aligned with this GridExtent.

    The 'clamp' parameter determines whether or not to clamp the Extent to the extent of this GridExtent; defaults to true. If true, the returned extent will be contained by this GridExtent's extent, if false, the Extent returned can be outside of this GridExtent's extent.

    cellBounds

    The extent to get the grid bounds for

    clamp

    A boolean which controls the clamping behavior

    Gets the GridBounds aligned with this GridExtent that is the smallest subgrid containing all points within the extent.

    Gets the GridBounds aligned with this GridExtent that is the smallest subgrid containing all points within the extent. The extent is considered inclusive on it's north and west borders, exclusive on it's east and south borders. See geotrellis.raster.RasterExtent for a discussion of grid and extent boundary concepts.

    The 'clamp' flag determines whether or not to clamp the GridBounds to the RasterExtent; defaults to true. If false, GridBounds can contain negative values, or values outside of this GridExtent's boundaries.

    subExtent

    The extent to get the grid bounds for

    clamp

    A boolean

  25. final def gridColToMap(col: N): Double

    Creates a RasterExtent out of this GridExtent.

    Note

    Use with caution: if the number of columns or rows are larger than Int.MaxValue, this will throw an exception. Also, if columns * rows > Int.MaxValue, this will create a RasterExtent for a raster that could not be backed by any of the Array-backed tile types.

    Returns a GridExtent with the same extent, but a modified number of columns and rows based on the given cell height and width.

    This method can construct a GridExtent where the number of columns and rows do not align closely with an integer boundary. The caller is responsible for verifying that the provided cell sizes are appropriate for the intended use case.

    See https://github.com/locationtech/geotrellis/issues/3261 for details and an example. If you need a specific number of columns and rows, see java.lang.Object) withDimensions(targetCols, targetRows)
