I did a search for data and I am not seeing any results?[edit | edit source]

The first thing to check is your search dates. By default, EODMS searches use "Past 24 Hours". If you are looking NAPL imagery (which dates back to 1920) you should select either "Any Time" or specify a specific Start and End Date

Ordering[edit | edit source]

How do I order a National Air Photo Library Photo[edit | edit source]

  1. Follow the steps to search for a particular NAPL photo above.
  2. With results loaded, check the "Order" checkbox EODMS-FAQ-NAPL-CartTab.png
  3. Select your Media Type, File Format, Image Resolution, Level of Compression, check the "Select item(s)" checkbox and finally, click the "Update Cart" button. Note: If you would like a different Image Resolution than what is listed, you can specify later in another screen. EODMS-FAQ-NAPL-OrderScreen.png
  4. Review your cart one last time and click "Submit Aerial Photo Order" Note: While pricing shown as N/A on EODMS, these images are not free and payment will be made directly with the NAPL order desk once they process your order. For complete list of pricing you can visit: https://www.nrcan.gc.ca/earth-sciences/geomatics/satellite-imagery-air-photos/air-photos/photo-collection/9707 EODMS-FAQ-NAPL-CartSubmit.png
  5. Finally enter a name for your order and any additional comments, e.g. a custom image resolution, the reason you are making this purchase. EODMS-FAQ-NAPL-NameDesc.png
  6. Your order is now submitted to NAPL. Your cart will show as "SAVED" which is correct. You will also receive an email confirming receipt of your cart. Payment will be requested by the NAPL order desk my phone or email.

How do I know the prices of National Air Photo Library Photos[edit | edit source]

Full pricing on NAPL can always be found here: https://www.nrcan.gc.ca/earth-sciences/geomatics/satellite-imagery-air-photos/air-photos/photo-collection/9707

I received an email re: my NAPL order saying, "Your image request(s) (Order ID: 1234) have failed"[edit | edit source]

A failed email notification for an NAPL order can result 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.

If this is not the case, proceed to contact the EODMS support desk.

When I try to order a CCRS Thematic Dataset, I get an error, "You are not permitted to add more than 25 items to your cart. Please select fewer items or narrow your search for Value-Added Satellite Products"[edit | edit source]

Because of the time-series nature of CCRS thematic datasets, the size of the product depends on how wide you chose your start and end time. For example, attempting to download the MODIS 10-day composite time series product for all time (e.g. start time 2016 - 2019) amounts to a 1.36 TB product. To reduce the size of your product to enable ordering, re-do your search with a more narrow time window e.g. Jan 01 2019 - Jan 17 2019 which amounts to a smaller 26 GB.

Now that I have submitted my aerial photo order, how long does the order desk production process take?[edit | edit source]

Ordering times can vary. You can always followup on the status on your order by contacting the NAPL order desk directly: https://www.nrcan.gc.ca/earth-sciences/geomatics/satellite-imagery-air-photos/air-photos/photo-collection/9707

Download[edit | edit source]

How do I download my order data[edit | edit source]

When your order is ready, you will receive an email from EODMS with the subject "EODMS Image Request Delivery Notification" that looks like the below. You can use a web browser to access the FTP and HTTP links or the FTP client software of your choice for the FTP. When using the direct links in the email, you will need to supply the same username and password that you use to log on to the EODMS site.
