Hello,


I’m interested to use Landsat 8 images level 2 (surface reflectance).

The problem is that it seems like this data collection is not available in WMS:


for collection in DataCollection.get_available_collections():

    print(collection)

...

DataCollection.LANDSAT8

When I print information about this data collection seems like only level 1 is available :


DataCollection.LANDSAT8



>>> <DataCollection.LANDSAT8: DataCollectionDefinition( 

api_id: L8L1C 

catalog_id: landsat-8-l1c 

wfs_id: DSS6 

service_url: :https://services-uswest2.sentinel-hub.com](https://services-uswest2.sentinel-hub.com/) 

collection_type: Landsat 8 

processing_level: L1C bands: ('B01', 'B02', 'B03', 'B04', 'B05', 'B06', 'B07', 'B08', 'B09', 'B10', 'B11') 

is_timeless: False 

has_cloud_coverage: True )>

In additon to that, when I try to create new Landsat 8 level 2 layer, it seems like not all the bands are available:
image


How can I access this data collection?


Best regards 🙂

Hi @reutkeller,


let me try to answer all your questions.


  • landsat-8-l1c is an old, now deprecated, Landsat Collection 1, which will cease to exist end of June, see forum post.

  • for Collection 2 you should use landsat-ot-l1 and landsat-ot-l2

  • WFS ids are DSS12 for Level 1 and DSS13 for Level 2 (see info)

  • It might be that sentinelhub-py is not yet supporting this collection, but it should be straightforward to add it on your side (pull requests are welcome as well!)

  • the “Base products” In configuration utility are just the most commonly used composites. You can easily configure a new composite by following these instructions. You will find a list of available bands here.

So… Landsat 8 Collection 2 is for sure supported by WMS.

The DataCollection for Landsat Collection are not yet (pre)defined in sh-py, but following the rules in example it is possible to do it yourself.


The code for LandSat8, Level1 product from Collection 2 is thus:


landsat8_l1 = DataCollection.define(

    name = 'L8_C2_L1',

    api_id = 'LOTL1',

    catalog_id = 'landsat-ot-l1',

    wfs_id = 'DSS12',

    service_url = ServiceUrl.USWEST,

    collection_type = 'Landsat Collection 2',

    processing_level = 'L1',

    bands = ('B01', 'B02', 'B03', 'B04', 'B05', 'B06', 'B07', 'B08', 'B09', 'B10', 'B11', 'BQA'), 

    has_cloud_coverage = True

)

Hi @batic, I get the name error from your script:



NameError: name ‘ServiceUrl’ is not defined


The ServiceUrl enum is defined in data_collections.py, so you need to import it first:


from sentinelhub.data_collections import ServiceUrl

ServiceUrl.USWEST

> 'https://services-uswest2.sentinel-hub.com'

The other possibility is to add url to the landsat8_l1 definition as


...

service_url = 'https://services-uswest2.sentinel-hub.com',

...

@batic Thank you!

is there option to do the same for the level 2 data? Where can I get the parameters values to acess similarly the level 2 images?


Thank you very much 🙂

New version of sentinelhub-py was released yesterday, and these collections are now predefined.


Best of luck,

Matej

Thank you for your answer,

I experience unexcpected behavior, when I pront the available data collection it doesn’t show all the time the level two data:


for collection in DataCollection.get_available_collections():

    print(collection)


DataCollection.SENTINEL2_L1C

DataCollection.SENTINEL2_L2A

DataCollection.SENTINEL1

DataCollection.SENTINEL1_IW

DataCollection.SENTINEL1_IW_ASC

DataCollection.SENTINEL1_IW_DES

DataCollection.SENTINEL1_EW

DataCollection.SENTINEL1_EW_ASC

DataCollection.SENTINEL1_EW_DES

DataCollection.SENTINEL1_EW_SH

DataCollection.SENTINEL1_EW_SH_ASC

DataCollection.SENTINEL1_EW_SH_DES

DataCollection.DEM

DataCollection.DEM_MAPZEN

DataCollection.DEM_COPERNICUS_30

DataCollection.DEM_COPERNICUS_90

DataCollection.MODIS

DataCollection.LANDSAT8

DataCollection.SENTINEL5P

DataCollection.SENTINEL3_OLCI

DataCollection.SENTINEL3_SLSTR


I suggest checking if you are using the correct version of the package. You can do that in the code with:


import sentinelhub



print(sentinelhub.__version__)

The new version is 3.3.1.
