Measurement#

class datacube.model.Measurement(canonical_name=None, **kwargs)[source]#

Describes a single data variable of a Product or Dataset.

Must include, which can be used when loading and interpreting data:

  • name

  • dtype - eg: int8, int16, float32

  • nodata - What value represent No Data

  • units

Attributes can be accessed using dict [] syntax.

Can also include attributes like alternative names ‘aliases’, and spectral and bit flags definitions to aid with interpreting the data.

Methods:

clear()

copy()

Required as the super class dict method returns a dict and does not preserve Measurement class

dataarray_attrs()

This returns attributes filtered for display in a dataarray.

fromkeys([value])

Create a new dictionary with keys from iterable and values set to value.

get(key[, default])

Return the value for key if key is in the dictionary, else default.

items()

keys()

pop(k[,d])

If key is not found, d is returned if given, otherwise KeyError is raised

popitem()

Remove and return a (key, value) pair as a 2-tuple.

setdefault(key[, default])

Insert key with a value of default if key is not in the dictionary.

update([E, ]**F)

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values()

clear() None.  Remove all items from D.#
copy()[source]#

Required as the super class dict method returns a dict and does not preserve Measurement class

Return type

Measurement

dataarray_attrs()[source]#

This returns attributes filtered for display in a dataarray.

Return type

Dict[str, Any]

fromkeys(value=None, /)#

Create a new dictionary with keys from iterable and values set to value.

get(key, default=None, /)#

Return the value for key if key is in the dictionary, else default.

items() a set-like object providing a view on D's items#
keys() a set-like object providing a view on D's keys#
pop(k[, d]) v, remove specified key and return the corresponding value.#

If key is not found, d is returned if given, otherwise KeyError is raised

popitem()#

Remove and return a (key, value) pair as a 2-tuple.

Pairs are returned in LIFO (last-in, first-out) order. Raises KeyError if the dict is empty.

setdefault(key, default=None, /)#

Insert key with a value of default if key is not in the dictionary.

Return the value for key if key is in the dictionary, else default.

update([E, ]**F) None.  Update D from dict/iterable E and F.#

If E is present and has a .keys() method, then does: for k in E: D[k] = E[k] If E is present and lacks a .keys() method, then does: for k, v in E: D[k] = v In either case, this is followed by: for k in F: D[k] = F[k]

values() an object providing a view on D's values#
