- Map Matching – Snap inaccurate GPS coordinates to street segments.
Utilizing the Map Visualization, you’ll be able to visualize geospatial knowledge, 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, we have now two main safety updates—AWS Key Administration Service (AWS KMS) for buyer managed AWS KMS key help and Amazon Digital Personal Cloud (Amazon VPC) for geospatial operations within the buyer Amazon VPC setting.
AWS KMS buyer managed keys provide elevated flexibility and management by enabling clients to make use of their very own keys to encrypt geospatial workloads.
You need to use KmsKeyId to specify your individual key in StartEarthObservationJob and StartVectorEnrichmentJob as an non-compulsory parameter. If the shopper doesn’t present KmsKeyId, a service owned key will probably be used to encrypt the shopper content material. To study extra, see SageMaker geospatial capabilities AWS KMS Assist within the AWS documentation.
Utilizing Amazon VPC, you’ve got full management over your community setting and might extra securely hook up with your geospatial workloads on AWS. You need to use SageMaker Studio or Pocket book in your Amazon VPC setting for SageMaker geospatial operations and execute SageMaker geospatial API operations by way of an interface VPC endpoint in SageMaker geospatial operations.
To get began with Amazon VPC help, 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 title as com.amazonaws.us-west-2.sagemaker-geospatial and choose the VPC by which to create the VPC endpoint.
All Amazon S3 assets which are used for enter or output in EOJ and VEJ operations ought to have web entry enabled. If in case you have no direct entry to these Amazon S3 assets by way of the web, you’ll be able to 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 Assist within the AWS documentation.
