sisppeo.utils.products.CoordinatesMixin¶

class sisppeo.utils.products.CoordinatesMixin[source]¶

Bases: object

A Mixin which adds extra properties and methods related to coordinates.

Methods

`__init__`()
`extract_point`(data_var, coordinates[, ...])	Returns value(s) at the given coordinates.
`extract_points`(data_var, lst_coordinates[, ...])	Returns value(s) at each tuple of coordinates of the given list.
`index`(x, y)	Gets (i, j) from (x, y)
`xy`(i, j)	Gets (x, y) from (i, j).

Attributes

`bounds`	(xmin, ymin, xmax, ymax).
`res`	Returns the spatial resolution of this product.
`x`	Returns x-coords.
`y`	Returns y-coords.

property bounds¶

(xmin, ymin, xmax, ymax).

extract_point(data_var, coordinates, buffer=None, epsg=4326, mode='xy')[source]¶

Returns value(s) at the given coordinates.

Parameters

data_var – The name of the variable/DataArray of interest (e.g., a band, aCDOM, etc).
coordinates – A tuple of geographic or projected coordinates; see “mode”.
buffer – Optional; The radius (in pixels) of the circle (centered on coordinates) to extract. Defaults to None.
epsg – Optional; The EPSG code. Defaults to 4326.
mode – Optional; Either ‘xy’ or ‘latlon’. Defaults to ‘xy’.

Returns

An xr.DataArray containing the wanted information.

extract_points(data_var, lst_coordinates, buffer=None, epsg=4326, mode='xy')[source]¶

Returns value(s) at each tuple of coordinates of the given list.

Parameters

data_var – The name of the variable/DataArray of interest (e.g., a band, aCDOM, etc).
lst_coordinates – A list of tuples of geographic or projected coordinates; see “mode”.
buffer – Optional; The radius (in pixels) of the circle (centered on coordinates) to extract. Defaults to None.
epsg – Optional; The EPSG code. Defaults to 4326.
mode – Optional; Either ‘xy’ or ‘latlon’. Defaults to ‘xy’.

Returns

A list of xr.DataArray (one per coordinates tuple) containing the wanted information.
