Using Imagery Catalogs
In the Imagery panel, you can switch between imagery catalogs to view different imagery types.
Available Imagery Catalogs
The following imagery catalogs are available in MGP Pro.
Archive Imagery contains a mix of panchromatic (black/white) and color imagery (up to 18 multispectral bands), with global coverage up to 30 cm resolution. Maxar's 125+ petabyte archive imagery library dates to 1999.
Archive Stereo Pairs are in-track images taken by the same satellite, approximately 45–90 seconds apart. These images are acquired at angles optimal for stereo viewing and manipulation.
In both card and list view, a yellow bar identifies archive stereo pairs.
Three archive stereo pairs, shown in list view.
Online Imagery is the most current imagery delivered by the Maxar constellation.
For more information, see Imagery Types.
Selecting an Imagery Catalog
Select Imagery. The Imagery panel opens.
From the Imagery Catalog drop-down, select an imagery catalog.
The Imagery panel refreshes to display imagery from the selected catalog.
The imagery catalog displays differently depending on the orientation of the Imagery panel.
Sortable and Filterable Metadata Fields
Metadata fields are sometimes visible, but cannot be used for sorting or filtering. Additionally, sortable and filterable metadata fields are different when you are viewing archive imagery than when you are viewing online imagery. Use the table below to determine whether or not a metadata field in MGP Pro is sortable or filterable when viewing different imagery catalogs.

More About Imagery Catalogs
Archive imagery displays in reduced resolution.
If you switch between imagery catalogs while filters are applied, your current filter settings are preserved.
If a filter setting exists in the online imagery catalog, but does not exist in the archive imagery catalog (e.g., NIIRS), the online dataset remembers that filter when you switch back to the online imagery catalog.
See Filtering Imagery.
The archive imagery library dates back to 1999. When you view an area, there may be thousands of images available in that area. To provide the best user experience, the archive image service only requests a few pages of imagery results at any time. However, the total number of results may be unclear (e.g, "200+"), because there are more results available than can be displayed.
To view more results:
Use the pagination options to increase the number of imagery results on each page, therefore increasing the number of total results available.
Use filters to narrow down the imagery results to locate imagery within a certain acquisition date, with a specific cloud cover, etc. See Filtering Imagery.
