[08/20/2009] Notice: We have discovered that the RotationTracks product has been incomplete from 14 August 2009 until the present time. We should have the data feed corrected shortly. However, we will need to try to backfill the data since 14 August 2009. An update message will be issued when we know more about restoring those data. Again, this affects the RotationTracks product only for the time period 14 August 2009 to 20 August 2009... (klm 1633z)

[04/13/2009] Notice: There appears to be an issue with the interactive preview image on the results page when running under Firefox 3.x. We are looking into this. This does not affect the OnDemand processing, nor the output files. Other web browsers do not appear to have this issue.

Original Notice

NSSL On Demand Algorithm Output :: About->Example

Example (Results):

The following illustrates what you can do at your 'Results' page. Upon a successfull submission, you will be shown a confirmation page with a link to your results page (this link will also be in your confirmation email). This page will be available for 7 days from your submission date to preview and retrieve your data. If your submission is not what you had hoped for, or if you do not view/retreive your data within the 7 day period, you must resubmit your request.

 

When you first visit your results page, it might look something like this (especially if you visit that page immediately after submitting your selection):

Initial Results

This is normal and means that the background processing hasn't started yet. Once The processing has begun - but not completed, your results page may look like this:

Initial Results

Note the bottom of the page. If our data are not yet ready, the section will be red, indicating that your data are still being processed. Also, the only thing you can do is review your submission.

Sometime the images will be ready before the rest of the data. If this is the case, you can preview you data in the large map. In other words, you will be able to zoom and pan the map to see what your data will look like once they are ready. (see the images below)

When your data are ready, the bottom section will be green and will be followed by a link to the zipped bundle containing your data. Click on this link (you may need to CTRL-Right Click and select "Save As") to save your data. The zipped bundle will contain several files and possibly some folders, which are all related to your output file request. Based on your request, the top level of files in the .zip file may contain

Contents of Zip File

 

Also, instead of a transparent blue area indicating the location you selected, your data (e.g. MESH) will be displayed witha blue line surrounding your selected area:

Results Are Ready

Depending on what products you chose, you can toggle between them as well as the "area" polygon. You can also "preview" your data by zooming in on your data. Zooming is done by clicking and dragging an area on the large map. A single click (without dragging) will recenter the map (at the current extent). The smaller map will provide a reference of your zoomed in area.
