class datacube.utils.geometry.gbox.GeoboxTiles(box, tile_shape)

Partition a GeoBox into sub geoboxes

Construct from a GeoBox.

Parameters:

• box (GeoBox) – the source GeoBox

• tile_shape (tuple[int, int]) – Shape of sub-tiles in pixels (rows, cols)

__init__(box, tile_shape)

Methods

__init__(box, tile_shape)
chunk_shape(idx)	Chunk shape for a given chunk index.
range_from_bbox(bbox)	Compute rows and columns overlapping with a given BoundingBox
tiles(polygon)	Return tile indexes overlapping the polygon

Attributes

base	The base GeoBox
shape	Number of tiles along each dimension

property base: GeoBox

The base GeoBox

chunk_shape(idx)

Chunk shape for a given chunk index.

Parameters:

idx (tuple[int, int]) – (row, col) index

Raises:

IndexError when index is outside of [(0,0) -> .shape)

Return type:

tuple[int, int]

Returns:

tuple (nrow, ncols) shape of a tile (edge tiles might be smaller)

range_from_bbox(bbox)

Compute rows and columns overlapping with a given BoundingBox

Return type:

tuple[range, range]

property shape

Number of tiles along each dimension

tiles(polygon)

Return tile indexes overlapping the polygon

Return type:

Iterable[tuple[int, int]]
