| − | === I received an email saying my order has failed. Why? ===
| |
| − | A failed email notification for an order is often for the following reasons:
| |
| − | # For NAPL: It often results if you attempted to use the "Reconfigure and Submit Order" menu option on an order which is already properly "SAVED". Doing this not necessary as submitting the order the first time correctly sends an email to the NAPL order desk for processing. An order marked as "SAVED" is correct and no further action is required on your part and you can ignore the failed notification.
| |
| − | # For RCM: For general public users, orders often fail because an order was placed on an item that is not available to the public. For more information on RCM open data, consult [https://wiki.gccollab.ca/Earth_Observation_Data_Management_System_(EODMS)#EODMS RCMOpenData]. If you are interested in expanded RCM Vetted access, please see [https://wiki.gccollab.ca/Earth_Observation_Data_Management_System_(EODMS)#RADARSAT_CONSTELLATION_MISSION_.28RCM.29 RCM Vetted Access]
| |
| − | # For any other situation, we invite you to re-submit your order using the Resubmit option as follows:
| |

You should instead login (or register for an account) and once logged-in, re-do your search by selecting the "RADARSAT-1 Open Data Products [Online]" or the "RADARSAT-2 Products [Online]" collection.
