  • Vector Enrichment jobs – Enrich your information with operations, similar to changing geographical coordinates to readable addresses.
  • Map Visualization – Visualize satellite tv for pc photos or map information uploaded from a CSV, JSON, or GeoJSON file.

You may create all Earth Commentary Jobs (EOJ) within the SageMaker Studio pocket book to course of satellite tv for pc information utilizing purpose-built geospatial operations. Here’s a checklist of purpose-built geospatial operations which might be supported by the SageMaker Studio pocket book:

  • Band Stacking – Mix a number of spectral properties to create a single picture.
  • Cloud Masking – Establish cloud and cloud-free pixels to get improved and correct satellite tv for pc imagery.
  • Cloud Removing – Take away pixels containing components of a cloud from satellite tv for pc imagery.
  • Geomosaic – Mix a number of photos for larger constancy.
  • Land Cowl Segmentation – Establish land cowl sorts similar to vegetation and water in satellite tv for pc imagery.
  • Resampling – Scale photos to totally different resolutions.
  • Spectral Index – Get hold of a mix of spectral bands that point out the abundance of options of curiosity.
  • Temporal Statistics – Calculate statistics by time for a number of GeoTIFFs in the identical space.
  • Zonal Statistics – Calculate statistics on user-defined areas.

A Vector Enrichment Job (VEJ) enriches your location information by purpose-built operations for reverse geocoding and map matching. Whereas it’s good to use a SageMaker Studio pocket book to execute a VEJ, you may view all the roles you create utilizing the consumer interface. To make use of the visualization within the pocket book, you first must export your output to your Amazon S3 bucket.

  • Reverse Geocoding – Convert coordinates (latitude and longitude) to human-readable addresses.
  • Map Matching – Snap inaccurate GPS coordinates to street segments.

Utilizing the Map Visualization, you may visualize geospatial information, the inputs to your EOJ or VEJ jobs in addition to the outputs exported out of your Amazon Easy Storage Service (Amazon S3) bucket.

Safety Updates
At GA, now we have two main safety updates—AWS Key Administration Service (AWS KMS) for buyer managed AWS KMS key assist and Amazon Digital Non-public Cloud (Amazon VPC) for geospatial operations within the buyer Amazon VPC setting.

AWS KMS buyer managed keys provide elevated flexibility and management by enabling prospects to make use of their very own keys to encrypt geospatial workloads.

You should use KmsKeyId to specify your personal key in StartEarthObservationJob and StartVectorEnrichmentJob as an optionally available parameter. If the client doesn’t present KmsKeyId, a service owned key shall be used to encrypt the client content material. To study extra, see SageMaker geospatial capabilities AWS KMS Help within the AWS documentation.

Utilizing Amazon VPC, you’ve full management over your community setting and might extra securely connect with your geospatial workloads on AWS. You should use SageMaker Studio or Pocket book in your Amazon VPC setting for SageMaker geospatial operations and execute SageMaker geospatial API operations by an interface VPC endpoint in SageMaker geospatial operations.

To get began with Amazon VPC assist, configure Amazon VPC on SageMaker Studio Area and create a SageMaker geospatial VPC endpoint in your VPC within the Amazon VPC console. Select the service identify as com.amazonaws.us-west-2.sagemaker-geospatial and choose the VPC through which to create the VPC endpoint.

All Amazon S3 assets which might be used for enter or output in EOJ and VEJ operations ought to have web entry enabled. You probably have no direct entry to these Amazon S3 assets through the web, you may grant SageMaker geospatial VPC endpoint ID entry to it by altering the corresponding S3 bucket coverage. To study extra, see SageMaker geospatial capabilities Amazon VPC Help within the AWS documentation.
