The Result screen's map view displays too many image footprints to make sense of. Can I simplify it?
A couple of tips:
- Checking "Select" or clicking the first hyperlink in a given result on the left will centre the map over the corresponding image on the right.
- Clicking a footprint on the map to the right of the results presents a "Select Result" link, which if clicked, highlights the corresponding result row on the left.
- Results can be be hidden using the "View only selected footprints" menu option in the top left of the results screen.
- Position your mouse in any column header until a blue down-arrow appears. Click it
- Next click, Columns, which will open up the list of columns
- Hide and Show different columns by checking and unchecking
While the result columns show some information, full metadata can be accessed:
- Scrolling the results table to the right by using the horizontal scroll bar along the bottom
- Clicking the "View" link in the "Metadata" column.
- Above the results, click on the "Select Option" menu button
- Choose, "Save Search Results"
- Choose the desired format
- Scroll to the right until you see the "Thumbnail" column.
- click the checkbox
- Observe the preview on the map.
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 physical photo film only.
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.

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 and to you. An order marked as "SAVED" is correct and no further action is required on your part. You can ignore the failed notification.
- For RCM: For 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://github.com/eodms-sgdot/eodms-website/wiki#public.
- 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.

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
