ODD PI 25.2 Objective 2: Demonstrate how to tile HLS using titiler-cmr

[hrodmn]

Motivation

High-value dataset of interest to many users and use cases.

Description

HLS can be configured in the VEDA dashboard for visualization in its explore page. Providing HLS tiles will demonstrate production-readiness of titiler-cmr. However, due to its many small tiles/scenes, delivering global mosaics will not be practical. Visualization of HLS tiles should be restricted to a zoom level where tiles will be rendered within the API timeout (30 seconds). The usability of the default experience and potential UI changes to instruct the user about appropriate zooms.

Acceptance Criteria

• Document how to use titler-cmr for HLS and current performance/zoom limitations. The intended audience is ESDIS (Worldview/GIBS) team to test it out in future PIs.
  • How to send requests
  • What's the max number of input granules that tiler can render with acceptable performance? At what zoom levels will tiles be reliably delivered? Does this depend on the bands/band combination and the number of tiles being requested at once?
• HLS data is available in the VEDA map explorer (preview is okay, but staging or prod deployment is preferred). If necessary, information on how and where to zoom is provided. Will require HLS STAC collection (just collection metadata) published to VEDA STAC catalog.
• Bonus: Get metrics on current performance of FIRMS tiler and usage of FIRMS
