Working with Results[edit | edit source]

The Result screen's map view displays too many image footprints to make sense of[edit | edit source]



You can hide result thumbnails using the "View only selected footprints" menu option in the top left of the results screen.

  2. Next click, Columns, which will open up the list of columns
  3. Hide and Show different columns by checking and unchecking

  1. Scrolling the results view to the right by using the horizontal scroll bar along the bottom

  2. click the checkbox
  3. Observe the preview on the map.
  4. Note: In the case of NAPL aerial photos, you may see a place holder image. This usually means digitization has not been completed and the photo still resides on film only. You can contact NAPL directly to see if they can provide a preview:


Ordering[edit | edit source]

How do I order an image?[edit | edit source]

  1. With results loaded, check the "Order" checkbox EODMS-FAQ-NAPL-CartTab.png
  2. Check the "Select item(s)" checkbox
  3. Finally, click the "Update Cart" button.
  4. Observe a new cart tab appears.

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.

I am trying to order RADARSAT images, but when I click the order checkbox I am presented with Order Desk information[edit | edit source]

This message is presented for the *RADARSAT-1 Raw Catalog* and *RADARSAT-2 Raw Catalog* collections. You should instead re-do your search by selecting the "RADARSAT-1 Open Data Products [Online]" or the "RADARSAT-2 Products [Online]" collection.

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". To download your data, you have a few options:

  1. Click the ftp link in the email e.g. ftp://data.eodms-sgdot.nrcan-rncan.gc.ca/public/carts/xxx-xxx-xxx-xxx-xxxx to open a browser and prompt you to enter your EODMS username and password.
  2. Click the https link in the email e.g. https://data.eodms-sgdot.nrcan-rncan.gc.ca/public/carts/xxx-xxx-xxx-xxx-xxxx to open a browser and prompt you to enter your EODMS username and password.
  3. Use an FTP client (e.g. Filezilla, Windows Command Line ftp.exe) and use hostname data.eodms-sgdot.nrcan-rncan.gc.ca, and your EODMS username and password. If the setting allows, select to use Passive Mode.

Note: Some government departments have reported issues with FTP access. This is usually attributed to a firewall issue at the department end. FTP access to the open Internet is a service that should always be up.

I downloaded my image order. What software can I use to view the images?[edit | edit source]

QGIS[edit | edit source]

QGIS is a well-supported desktop GIS tool which supports a variety of GIS image formats. You can download QGIS for free from their website.


MapReady and Google Earth[edit | edit source]

Another method is to download MapReady from https://www.asf.alaska.edu/data-tools/mapready/. open your product (.sarl file, for example), leave all the defaults and click, process file. Finally, click on the Google Earth icon to display it. At this time, MapReady only supports RADARSAT-1 Product Type SGX. Mapready.png Rs1-google-earth.png

Can I just download satellite imagery without going through the whole order process?[edit | edit source]

For RADARSAT-1, Yes! You do not even need to login. Simply

  1. perform a search for RADARSAT-1
  2. Scroll to the right, until you see the "Download Link" column
