bounding box specification issue

[btupper]

Hi,

I don't seem to have control over the the bounding box for a subscription. Below I show two commands for subscription (a) no -b specification and (b) specifying a small bounding box. The downloaded files are the same size (and each has the world-sized number of pixels.)

I can subset the local files, but it would consume fewer resources if we could transfer just the smaller subset.

Thanks! Ben

(a) the world (bounding box unspecified)

(b) a smaller subset specified by the -b argument.

Hi Brian,

This is actually working as intended right now. The 'bbox' parameter only filters search results that do not pass through your region of interest. Because MUR data are essentially global data products, any bbox will match, and it downloads the entire file.

We have some work in progress on this exact functionality: https://github.com/podaac/data-subscriber/issues/36

Its still in development, but the good news is your data set (MUR) is high on the list of test cases for it. when this is delivered, an option -subset parameter will be provided to actually subset based on your space (bbox)and time bounds (start/stop dates).

We definitely appreciate the comment and detailed report, and are working hard to get the subset work pushed out to the users.

Oh, I see. Thank you! Ben
