Data collections - Amazon SageMaker
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Data collections

Amazon SageMaker geospatial supports the following raster data collections. Of the following data collections, you can use the USGS Landsat and the Sentinel-2 Cloud-Optimized GeoTIFF data collections when starting an Earth Observation Job (EOJ). To learn more about the EOJs, see Earth Observation Jobs.

To find the list of available raster data collections in your Amazon Web Services Regions, use ListRasterDataCollections. In the ListRasterDataCollections response, you get a RasterDataCollectionMetadata object that contains details about the available raster data collections.

Example – Calling the ListRasterDataCollections API using the Amazon SDK for Python (Boto3)

When you use the SDK for Python (Boto3) and SageMaker geospatial, you must create a geospatial client, geospatial_client. Use the following Python snippet to make a call to the list_raster_data_collections API:

import boto3 import sagemaker import sagemaker_geospatial_map import json ## SageMaker Geospatial Capabilities is currently only avaialable in US-WEST-2 session = boto3.Session(region_name='us-west-2') execution_role = sagemaker.get_execution_role() ## Creates a SageMaker Geospatial client instance geospatial_client = session.client(service_name="sagemaker-geospatial") # Creates a resusable Paginator for the list_raster_data_collections API operation paginator = geospatial_client.get_paginator("list_raster_data_collections") # Create a PageIterator from the Paginator page_iterator = paginator.paginate() # Use the iterator to iterate throught the results of list_raster_data_collections results = [] for page in page_iterator: results.append(page['RasterDataCollectionSummaries']) print (results)

In the JSON response, you will receive the following, which has been truncated for clarity:

{ "Arn": "arn:aws:sagemaker-geospatial:us-west-2:555555555555:raster-data-collection/public/dxxbpqwvu9041ny8", "Description": "Copernicus DEM is a Digital Surface Model which represents the surface of the Earth including buildings, infrastructure, and vegetation. GLO-30 is instance of Copernicus DEM that provides limited worldwide coverage at 30 meters.", "DescriptionPageUrl": "https://registry.opendata.aws/copernicus-dem/", "Name": "Copernicus DEM GLO-30", "Tags": {}, "Type": "PUBLIC" }
