wradlib.georef.raster.create_raster_xarray

wradlib.georef.raster.create_raster_xarray(crs, bounds, resolution, snap_bounds=False, snap_resolution=False)

Create empty raster as xarray dataset following CF conventions

Parameters:

• crs – Coordinate Reference System (CRS) mapping geographic to x,y coordinates. Must be provided and can be one of:

  • A pyproj.crs.CoordinateSystem instance

  • A cartopy.crs.CRS instance

  • A osgeo.osr.SpatialReference instance

  • A type accepted by pyproj.crs.CRS.from_user_input (e.g., EPSG code, PROJ string, dictionary, WKT, or any object with a to_wkt() method)

• bounds (tuple of int) – Bounding box as (min_x, min_y, max_x, max_y), as integer.

• resolution (int or tuple of int) – Grid resolution in x and y directions. If a single int is provided, it applies to both axes.

• snap_bounds (bool, optional) – If True, adjusts bounds to align with resolution grid.

• snap_resolution (bool, optional) – If True, adjusts resolution to evenly divide the extent.

Returns:

xarray.Dataset – An xarray Dataset with ‘x’ and ‘y’ pixel center coordinates, ‘spatial_ref’ coordinate with crs_wkt and GeoTransform attributes
