  2. Next, click on the "1. Select an Area of Interest" Search Criteria grouping (grey header #1)

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


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.


There are so many columns, how do I hide some or show different ones?[edit | edit source]

  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

I received an email from an NMSO commercial satellite provider (CSP). How do I download my NMSO data (Government of Canada only)[edit | edit source]

Once an NMSO CSP delivers data to NRCan, a government employee can

  1. Do a simple search as per above: https://wiki.gccollab.ca/EODMS_FAQ#Searching
  2. For *download only* (data that EODMS cannot yet load e.g. PLEIADES) proceed directly to https://data.eodms-sgdot.nrcan-rncan.gc.ca/ and enter their EODMS username/password. After that the data can be found using the following convention: https://data.eodms-sgdot.nrcan-rncan.gc.ca/<department>/<satellite>/<sensor> (e.g. https://data.eodms-sgdot.nrcan-rncan.gc.ca/dfo/pleiades/pleiades)
