.. py:function:: transform_crs(aoi_geometry: shapely.geometry.Polygon, src_crs: str, dst_crs: str) -> shapely.geometry.Polygon

   Transform area of interest geometry to another coordinate reference system.

   :param aoi_geometry: Geometry of the area of interest.
   :type aoi_geometry: Polygon
   :param src_crs: Source coordinate reference system.
   :type src_crs: str
   :param dst_crs: Destination coordinate reference system.
   :type dst_crs: str

   :returns: **aoi_geometry_transformed**
   :rtype: Polygon


.. py:function:: expand_bounds(bbox_coordinates: list, amount: float) -> list

   Expand bounding box coordinates by amount.

   :param bbox_coordinates: Bounding box coordinates [xmin, ymin, xmax, ymax].
   :type bbox_coordinates: list
   :param amount: Amount to expand the bounding box.
   :type amount: float

   :returns: **bbox_coordinates** -- Expanded bounding box coordinates [xmin, ymin, xmax, ymax].
   :rtype: list


.. py:function:: coordinate_arrays_from_profile(profile: dict) -> Tuple[numpy.ndarray, numpy.ndarray]

   Get coordinate arrays from rasterio profile.

   :param profile: Rasterio profile.
   :type profile: dict

   :returns: * **xs** (*np.ndarray*) -- Array of x coordinates.
             * **ys** (*np.ndarray*) -- Array of y coordinates.
