(GC only) The list of satellites under <Select Data> is missing a lot of NMSO satellites. How can I find this data?

EODMS can only load and map-search the satellites shown. However, all satellite data not loadable is stored on the EODMS Download Server with direct HTTP/FTP access. To find satellite data by name (e.g. "Flock1-ISS", "PLEIADES") we invite you to use Filezilla against data.eodms-sgdot.nrcan-rncan.gc.ca with the text search function:

Working with Results

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

Answer

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

There are so many columns, how do I hide some or show different ones?

1. Position your mouse in any column header until a blue down-arrow appears. Click it
2. Next click, Columns, which will open up the list of columns
3. Hide and Show different columns by checking and unchecking

How do I see the details of an image (i.e. metadata)?

While the result columns show some information, full metadata information can by:

1. Scrolling the results view to the right by using the horizontal scroll bar along the bottom
2. Clicking the "View" link in the "Metadata" column.

Is it possible to export the results including geometry (i.e. spatial info)

1. Above the results, click on the "Select Option" menu button
2. Choose, "Save Search Results"
3. Choose the desired format

How can I preview an image?

1. Scroll to the right until you see the "Thumbnail" column.
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:

https://www.nrcan.gc.ca/earth-sciences/geomatics/satellite-imagery-air-photos/air-photos/photo-collection/9707

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.

How do I order an image?

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

Are National Air Photo Library Photos Free?

No. Despite the "$0", order requires payment. 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

How do I know the prices of National Air Photo Library Photos

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 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 RCM #OpenData. If you are interested in expanded RCM Vetted access, please see RCM Vetted Access

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 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"

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?

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

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, 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?

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.

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.
