datacube.utils.geometry.gbox.GeoboxTiles

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

Partition GeoBox into sub geoboxes

Construct from a GeoBox

Parameters

• box (GeoBox) – source datacube.utils.geometry.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 with a given geometry.

Attributes

base	GeoBox
shape	Number of tiles along each dimension

Methods:

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 with a given geometry.

Attributes:

shape

Number of tiles along each dimension

chunk_shape(idx)

Chunk shape for a given chunk index.

Parameters

Return type

Tuple[int, int]

Returns

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

Raises

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

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 with a given geometry.

Return type

Iterable[Tuple[int, int]]
