geoutils.Raster

class geoutils.Raster(filename_or_dataset, bands=None, load_data=False, downsample=1, nodata=None)

The georeferenced raster.

Main attributes:

data: np.ndarray

Data array of the raster, with dimensions corresponding to (count, height, width).

transform: affine.Affine

Geotransform of the raster.

crs: pyproj.crs.CRS

Coordinate reference system of the raster.

nodata: int or float

Nodata value of the raster.

All other attributes are derivatives of those attributes, or read from the file on disk. See the API for more details.

__init__(filename_or_dataset, bands=None, load_data=False, downsample=1, nodata=None)

Instantiate a raster from a filename or rasterio dataset.

Parameters:

• filename_or_dataset (Union[str, Path, TypeVar(RasterType, bound= Raster), DatasetReader, MemoryFile, dict[str, Any]]) – Path to file or Rasterio dataset.

• bands (int | list[int] | None) – Band(s) to load into the object. Default loads all bands.

• load_data (bool) – Whether to load the array during instantiation. Default is False.

• downsample (Union[int, float, integer[Any], floating[Any]]) – Downsample the array once loaded by a round factor. Default is no downsampling.

• nodata (int | float | None) – Nodata value to be used (overwrites the metadata). Default reads from metadata.
