Download Cog

GET
/datasets/{dataset_id}/download/cog
 
curl --request GET \
  --url https://example.com/datasets/2489E9AD-2EE2-8E00-8EC9-32D5F69181C0/download/cog

Download the Cloud-Optimized GeoTIFF for a raster dataset.

On S3 storage with presigned downloads enabled, answers 302 to a short-lived presigned URL (at most 5 minutes, and never past the expiry of a ?token= download token); otherwise streams the object with Content-Type image/tiff. Even then, a GET carrying If-Match, or a resume whose If-Range no longer matches, is streamed. A COG imported by reference redirects to its origin. Accepts standard auth or ?token= JWT query parameter for browser downloads.

user may be None when a no-sub anonymous download token (issued by POST /auth/download-token/{id} for a public dataset) is presented on ?token=. The function branches on user-None to enforce public visibility and emit the audit row with user_id=NULL.
