At AWS re:Invent 2022, we previewed Amazon SageMaker geospatial abilities, enabling info researchers and device studying (ML) engineers to construct, educate, and deploy ML models using geospatial details. Geospatial ML with Amazon SageMaker supports entry to quickly accessible geospatial information, objective-created processing operations and open resource libraries, pre-skilled ML products, and built-in visualization tools with Amazon SageMaker’s geospatial capabilities.
Throughout the preview, we had lots of desire and good responses from consumers. These days, Amazon SageMaker geospatial abilities are normally available with new safety updates and further sample use circumstances.
Introducing Geospatial ML options with SageMaker Studio
To get started, use the fast set up to start Amazon SageMaker Studio in the US West (Oregon) Location. Make positive to use the default Jupyter Lab 3 version when you develop a new user in the Studio. Now you can navigate to the homepage in SageMaker Studio. Then choose the Info menu and click on Geospatial.
Listed here is an overview of three essential Amazon SageMaker geospatial capabilities:
- Earth Observation positions – Get, completely transform, and visualize satellite imagery information working with purpose-constructed geospatial operations or pre-trained ML products to make predictions and get useful insights.
- Vector Enrichment positions – Enrich your knowledge with operations, such as changing geographical coordinates to readable addresses.
- Map Visualization – Visualize satellite illustrations or photos or map details uploaded from a CSV, JSON, or GeoJSON file.
You can generate all Earth Observation Jobs (EOJ) in the SageMaker Studio notebook to system satellite info applying purpose-developed geospatial functions. Listed here is a list of purpose-built geospatial operations that are supported by the SageMaker Studio notebook:
- Band Stacking – Merge numerous spectral properties to generate a one graphic.
- Cloud Masking – Identify cloud and cloud-absolutely free pixels to get enhanced and correct satellite imagery.
- Cloud Removing – Clear away pixels that contains elements of a cloud from satellite imagery.
- Geomosaic – Combine many illustrations or photos for bigger fidelity.
- Land Protect Segmentation – Recognize land cover sorts this sort of as vegetation and water in satellite imagery.
- Resampling – Scale illustrations or photos to various resolutions.
- Spectral Index – Receive a blend of spectral bands that show the abundance of characteristics of fascination.
- Temporal Statistics – Work out statistics via time for multiple GeoTIFFs in the similar spot.
- Zonal Stats – Estimate studies on user-defined areas.
A Vector Enrichment Occupation (VEJ) enriches your place details by intent-created operations for reverse geocoding and map matching. When you require to use a SageMaker Studio notebook to execute a VEJ, you can see all the work opportunities you create applying the person interface. To use the visualization in the notebook, you initially have to have to 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.
Making use of the Map Visualization, you can visualize geospatial info, the inputs to your EOJ or VEJ careers as nicely as the outputs exported from your Amazon Simple Storage Support (Amazon S3) bucket.
Security Updates
At GA, we have two significant safety updates—AWS Important Management Service (AWS KMS) for consumer managed AWS KMS key help and Amazon Virtual Private Cloud (Amazon VPC) for geospatial functions in the client Amazon VPC setting.
AWS KMS client managed keys provide greater flexibility and management by enabling consumers to use their personal keys to encrypt geospatial workloads.
You can use KmsKeyId to specify your have critical in StartEarthObservationJob and StartVectorEnrichmentJob as an optional parameter. If the client does not supply KmsKeyId, a service owned essential will be made use of to encrypt the customer content. To learn additional, see SageMaker geospatial abilities AWS KMS Assist in the AWS documentation.
Utilizing Amazon VPC, you have comprehensive handle over your network setting and can a lot more securely connect to your geospatial workloads on AWS. You can use SageMaker Studio or Notebook in your Amazon VPC environment for SageMaker geospatial operations and execute SageMaker geospatial API functions via an interface VPC endpoint in SageMaker geospatial operations.
To get started with Amazon VPC guidance, configure Amazon VPC on SageMaker Studio Area and create a SageMaker geospatial VPC endpoint in your VPC in the Amazon VPC console. Decide on the provider name as com.amazonaws.us-west-2.sagemaker-geospatial and pick the VPC in which to produce the VPC endpoint.
All Amazon S3 resources that are used for enter or output in EOJ and VEJ operations really should have online entry enabled. If you have no direct entry to people Amazon S3 assets via the net, you can grant SageMaker geospatial VPC endpoint ID obtain to it by switching the corresponding S3 bucket plan. To study additional, see SageMaker geospatial abilities Amazon VPC Help in the AWS documentation.
