podpac.datalib.Landsat8

class podpac.datalib.Landsat8(**kwargs: Any)[source]

Bases: SatUtils

Landsat 8 on AWS OpenData https://registry.opendata.aws/landsat-8/

Leverages sat-utils (https://github.com/sat-utils) developed by Development Seed

Parameters:
  • asset (str, optional) – Asset to download from the satellite image. For Landsat8, this includes: ‘B01’,’B02’,’B03’,’B04’,’B05’,’B06’,’B07’,’B08’,’B09’,’B10’,’B11’,’B12’ The asset must be a band name or a common extension name, see https://github.com/radiantearth/stac-spec/tree/master/extensions/eo See also the Assets section of this tutorial: https://github.com/sat-utils/sat-stac/blob/master/tutorial-2.ipynb

  • query (dict, optional) – Dictionary of properties to query on, supports eq, lt, gt, lte, gte Passed through to the sat-search module. See https://github.com/sat-utils/sat-search/blob/master/tutorial-1.ipynb Defaults to None

  • min_bounds_span (dict, optional) – Default is {}. When specified, gives the minimum bounds that will be used for a coordinate in the query, so it works properly. If a user specified a lat, lon point, the query may fail since the min/max values for lat/lon are the same. When specified, these bounds will be padded by the following for latitude (as an example): [lat - min_bounds_span[‘lat’] / 2, lat + min_bounds_span[‘lat’] / 2]
