hydromt.readers.open_raster_from_tindex(tindex_path: str, *, bbox: tuple[float, float, float, float] | None = None, geom: GeoDataFrame | GeoSeries | None = None, tileindex: str = 'location', mosaic_kwargs: dict | None = None, filesystem: AbstractFileSystem | None = None, **kwargs)[source]#

Read and merge raster tiles.

Raster tiles can potentially be in different CRS. Based on a tile index file as generated with gdaltindex. A bbox or geom describing the output area of interest is required.

Parameters:

  • tindex_path (path, str) – Path or URI of the tile index file.

  • bbox (tuple of floats, optional) – (xmin, ymin, xmax, ymax) bounding box in EPGS:4326, by default None.

  • geom (geopandas.GeoDataFrame/Series, optional) – A geometry defining the area of interest, by default None. The geom.crs defaults to EPSG:4326 if not set.

  • tileindex (str) – Field name to hold the file path/location to the indexed rasters

  • mosaic_kwargs (dict, optional) – Mosaic key_word arguments to unify raster crs and/or resolution. See merge() for options.

  • filesystem (AbstractFileSystem | None, optional) – fsspec filesystem to read the tile index and the tiles from. None (default) means the local filesystem.

  • **kwargs – key-word arguments are passed to hydromt.readers.open_mfraster()

Returns:

data – A single-variable Dataset of merged raster tiles.

Return type:

xr.Dataset
