Module Contents

satellitetools.common.vector.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.

Parameters:

• aoi_geometry (Polygon) – Geometry of the area of interest.

• src_crs (str) – Source coordinate reference system.

• dst_crs (str) – Destination coordinate reference system.

Returns:

aoi_geometry_transformed

Return type:

Polygon

satellitetools.common.vector.expand_bounds(bbox_coordinates: list, amount: float) → list

Expand bounding box coordinates by amount.

Parameters:

• bbox_coordinates (list) – Bounding box coordinates [xmin, ymin, xmax, ymax].

• amount (float) – Amount to expand the bounding box.

Returns:

bbox_coordinates – Expanded bounding box coordinates [xmin, ymin, xmax, ymax].

Return type:

list

satellitetools.common.vector.coordinate_arrays_from_profile(profile: dict) → Tuple[numpy.ndarray, numpy.ndarray]

Get coordinate arrays from rasterio profile.

Parameters:

profile (dict) – Rasterio profile.

Returns:

• xs (np.ndarray) – Array of x coordinates.

• ys (np.ndarray) – Array of y coordinates.
