Return a clipped, sliced and unified GeoDataset.
To clip the data to the area of interest, provide a bbox or geom, with optional additional buffer argument. To slice the data to the time period of interest, provide the time_range argument. To return only the dataset variables of interest provide the variables argument.
NOTE: Unless single_var_as_array is set to False a single-variable data source will be returned as xarray.DataArray rather than Dataset.
- Parameters:
data_like (
Union[ str
,SourceSpecDict
,Path
,xr.Dataset
,xr.DataArray
,GeoDatasetSource ]
) – Data catalog key, path to GeoDataset file, a GeoDatasetSource object, or GeoDataset xarray object. The catalog key can be a string or a dictionary with the following keys: {‘name’, ‘provider’, ‘version’}. If a path to a file is provided it will be added to the catalog with its based on the file basename.bbox (
Optional[List]
, optional) – (xmin, ymin, xmax, ymax) bounding box of area of interest (in WGS84 coordinates), by default Nonegeom (
Optional[gpd.GeoDataFrame]
, optional) – A geometry defining the area of interest, by default Nonebuffer (
Union[float
,int]
, optional) – Buffer around the bbox or geom area of interest in meters, by default 0handle_nodata (
NoDataStrategy
, optional) – How to react when no data is found, by default NoDataStrategy.RAISEpredicate (
str
, optional) – If predicate is provided, the GeoDataSet is filtered by testing the predicate function against each item. Requires bbox or mask. options are: {‘intersects’, ‘within’, ‘contains’, ‘overlaps’, ‘crosses’, ‘touches’}, by default ‘intersects’variables (
Optional[List]
, optional) – Names of GeoDataset variables to return, or all if None, by default Nonetime_range (
Optional[TimeRange]
, optional) – Start and end date of period of interest, or entire period if None, by default Nonesingle_var_as_array (
bool
, optional) – Wether to return a xr.DataArray if the dataset consists of a single variable, by default Trueprovider (
Optional[str]
, optional) – Specifies a data provider, by default Noneversion (
Optional[str]
, optional) – Specifies a data version, by default None**kwargs – Extra keyword arguments passed to the GeoDatasetSource construction
- Returns:
a clipped, sliced and unified GeoDataset
- Return type:
xr.Dataset
- Raises:
ValueError – If data_like is of an unknown type
NoDataException – If no data is found and handle_nodata is NoDataStrategy.RAISE
