Using worldwide terrain in AWS serverless backend


We need to find a way to get worldwide terrain elevation data at as high as possible quality for various data enrichment tasks.
Throughput may be very high, potentially up to 1,000,000s of points per day.

My question:

  • Because it’s using by our backend AWS serverless data pipelines (Node.js & Python), what’re the best approaches for high-throughput elevation data such as they consume for the Cesium front-end?
  • Do you have any general advice around handling/working with/acquiring/serving terrain elevation data?
