Xarray
Xarray est une bibliothèque de tableaux multidimensionnels Python et un framework de jeux de données étiquetés. Elle étend la structure de données NumPy en ajoutant des étiquettes aux tableaux, permettant l'organisation de données N-dimensionnelles complexes en utilisant des dimensions et des coordonnées nommées.
La bibliothèque fournit une interface de données NetCDF pour lire et écrire des formats de données scientifiques tels que NetCDF et Zarr. Elle permet le calcul scientifique sur tableaux en maintenant la relation entre les données et les coordonnées physiques pendant les opérations mathématiques.
Le projet couvre l'analyse de données multidimensionnelles, la manipulation de données géospatiales et le traitement de données climatiques. Il prend également en charge l'analyse de séries temporelles pour gérer des séquences d'observations au fil du temps.
Features
- Labeled Array Management - Provides a framework for organizing multidimensional datasets using named dimensions and coordinates to avoid integer indexing.
- Labeled Dataset Aggregations - Groups multiple labeled arrays into a single container using a shared set of coordinates and global attributes.
- Labeled Dataset Frameworks - Provides a system for organizing complex multidimensional data with metadata and coordinate-based alignment.
- Dimension Coordinate Mapping - Maps named dimensions to integer axis indices to automate coordinate alignment and array slicing.
- Multidimensional Arrays - Enables analysis of large arrays of data using named dimensions and labels instead of raw integer indexing.
- Scientific Computing - Performs mathematical operations on labeled N-dimensional arrays while maintaining the relationship between data and physical coordinates.
- N-Dimensional Array Libraries - Provides a library for managing labeled N-dimensional arrays and datasets using named dimensions and coordinates.
- NumPy Array Integration - Uses NumPy arrays as the underlying data container to leverage efficient contiguous memory and vectorised operations.
- Labeled Array Extensions - Extends the NumPy data structure by adding labels to arrays to simplify indexing and data analysis.
- Deferred Computation Integration - Wraps Dask arrays to defer computation until a result is explicitly requested.
- Time Series Analysis - Manages sequences of multidimensional observations over time, allowing for easy resampling and alignment of temporal data.
- Array Broadcasting - Implements array broadcasting to automatically align datasets by matching labels across dimensions during arithmetic operations.
- Climate Data Processing - Handles complex atmospheric or oceanic datasets that use coordinates like latitude, longitude, and time.
- Geospatial Data Manipulation - Works with spatially referenced grids and datasets to slice, dice, and align data based on geographic coordinates.
