[Landsat-pds] usgs service issues?

[Frank Warmerdam]

Amit,

I was only downloading one scene on that connection, but other processes
were potentially processing others at the same time.

Currently I only ever pass one scene id to the request to get download urls
though it was using, not requesting the download url that failed.

Best regards,
Frank
