The Result screen's map view displays too many image footprints to make sense of

How can I preview an image?

  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.

Why do only certain aerial photos have a preview?

While the EODMS catalog contains over 3.5M aerial photo records, only a percentage of those have actually been digitized from original film. Only successfully digitized photos which have been loaded into the system have a preview available.

I received an email saying my order has failed. Why?

A failed email notification for an order is often for the following reasons:

  1. 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.
  2. 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 RCMOpenData. If you are interested in expanded RCM Vetted access, please see RCM Vetted Access
  3. For any other situation, we invite you to re-submit your order using the Resubmit option as follows:

 

To verify the order failed reason, simply click on the Order Status link on the homepage and then on the order name. Use the Contact Us page if you still require help.

I am trying to order RADARSAT images, but when I click the order checkbox I am presented with Order Desk information

This message is presented to users who are not logged in as well as for RAW collections (e.g. *RADARSAT-1 Raw Catalog*, *RADARSAT-2 Raw Catalog*). 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.

Now that I have submitted my aerial photo order, how long does the order desk production process take?

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

How do I create a standing order?

Download

How do I download my order data

When your order is ready, you will receive an email from EODMS with the subject "EODMS Image Request Delivery Notification". To download your data, 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.

How do I bulk-download files without having to click one-by-one in my browser

We invite you to use a terminal to download your orders. Don't forget the trailing '/' at the end of the url directory:

For a restricted cart, using username and password (for RCM data): 

 wget --recursive -e robots=off --no-parent -l inf --no-directories --http-user XXX --http-password XXX https://data.eodms-sgdot.nrcan-rncan.gc.ca/rcm/carts/123456789-cc12-4e0b-93dc-b11ab84fd1fd/

For, for public cart (e.g. NAPL, RADARSAT-1, Canada Lands) you may run without username and password: 

 wget --recursive -e robots=off --no-parent -l inf --no-directories https://data.eodms-sgdot.nrcan-rncan.gc.ca/public/carts/123456789-cc12-4e0b-93dc-b11ab84fd1fd/

You can also bulk download open data, such as all the NRCan emergency flood maps for 2023 

 wget --recursive -e robots=off --no-parent -l inf --no-directories https://data.eodms-sgdot.nrcan-rncan.gc.ca/public/EGS/2023/Flood/CAN/QC/

...or all the NAPL photos for roll number 22042 captured of Tuktoyaktuk, NWT: 

 wget --recursive -e robots=off --no-parent -l inf --no-directories https://data.eodms-sgdot.nrcan-rncan.gc.ca/public/NAPL_PNA/22000/22042/

If you are on Windows, you can download wget from https://eternallybored.org/misc/wget/. You can also customize directory options per https://www.gnu.org/software/wget/manual/wget.html#Directory-Options. `CTRL+C` to interrupt. For more advanced users, we recommend the https://github.com/eodms-sgdot/eodms-cli to perform searches, save results and downloads all from the command line.

I downloaded my image order. What software can I use to view the images?

QGIS

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

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.    

Can I just download satellite imagery without going through the whole order process?

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
  3. Click the link and voila!
 

For all other collections, this service is not yet available. The EODMS team is working hard to make this service available for all open collections.

My RCM order was fulfilled with more than 1 product zip files

e.g. 

 RCMX_OKXXXXXX_PKXXXXXXX_1_BEAMMODE_20XXXXXX_XXXXXX_VV_VH_GRD.zip, RCMX_OKXXXXXX_PKXXXXXXX_2_BEAMMODE_20XXXXXX_XXXXXX_VV_VH_GRD.zip.

Often images are acquired in a longer swaths and then when processed, are broken down into multiple products/images. SAR image processing applications can typically stitch them back together.
