Using Card View and List View

In the Imagery panel, you can switch between card view and list view. Each view has unique functionality.

Using Card View

Card view is ideal for selecting imagery because you can see thumbnails of each image in the Imagery panel. Card view is the default view for the Imagery panel when viewing online imagery.

Card view is the default view for the Imagery panel when viewing online imagery. If the Imagery panel is currently in list view, you can switch back to card view from the Imagery panel toolbar.

  1. Zoom to level 11 or higher.

  2. Select Imagery. The Imagery panel opens.

  3. On the Imagery panel toolbar, select Card View Imagery panel: card view off.

    When in list view, you can switch back to card view from the Imagery panel toolbar.

You can use card view to select imagery and work with it in the viewport. You can perform the following basic image-related tasks in card view:

  • Toggle the image selection checkbox.

  • Hover over any card to see the corresponding image's footprint outlined in the viewport. The footprint shows the image acquisition date.

  • Drag and drop cards to reorder them and change their stacking order in the viewport.

When using card view at lower zoom levels (13.9 – 11), you will see a generic overlay on the card. This overlay provides basic image metadata to help you quickly locate the imagery you want to view.

Imagery results are not available below zoom level 11.

When using card view at zoom level 14 and above, you will see a small basemap on each thumbnail image. This thumbnail image serves as a "mini viewport" to indicate where the image strip is in the viewport.

The Imagery panel shows several images with thumbnails. An image is selected in the panel and indicated in the viewport as well as in the mini viewport.

When looking at the mini viewport, remember:

  • The mini viewport includes the area underneath the Imagery panel.

  • The Imagery panel locks when you select an image. When locked, the imagery in the Imagery panel does not refresh when you pan or zoom. This includes thumbnail images, so the mini viewport may not be accurate if you pan or zoom after the Imagery panel locks.

Using List View

List view is ideal for working with image metadata. In list view, you can edit the visible metadata fields and sort images by metadata. List view is the default view for the Imagery panel when viewing the archive imagery catalog.

List view is the default view for the Imagery panel when viewing the archive imagery catalog. If the Imagery panel is currently in card view, you can switch to list view from the Imagery panel toolbar.

  1. Zoom to level 11 or higher.

  2. Select Imagery. The Imagery panel opens.

  3. On the Imagery panel toolbar, select List View Imagery panel: list view off.

    When in card view, you can switch back to list view from the Imagery panel toolbar.

You can use list view to select imagery and work with it in the viewport. You can perform the following image-related tasks in list view:

  • Toggle the image selection checkbox.

  • Hover over any metadata row to see the corresponding image's footprint outlined in the viewport.

  • Drag and drop images in the list to reorder them and change their stacking order in the viewport.

When you open list view, you will see default metadata columns. These columns vary depending on whether you are in vertical or horizontal orientation.

  • Default Metadata Attributes: Vertical Orientation

    • Acquisition Date

    • Cloud Cover

    • Sensor

  • Default Metadata Attributes: Horizontal Orientation: Online Imagery

    • Acquisition Date

    • Age Days

    • Acquisition Time UTC

    • Sensor

    • Ground Sample Distance (GSD)

    • Cloud Cover

    • Off-Nadir Angle (ONA)

    • Image ID

    • Archive Catalog ID

  • Default Metadata Attributes: Horizontal Orientation: Archive Imagery

    • Acquisition Date

    • Sensor

    • Ground Sample Distance (GSD)

    • Cloud Cover

    • Off-Nadir Angle (ONA)

    • Archive Catalog ID

List view allows you to see a large amount of image metadata in one place. If you do not want to use the default metadata attributes, you can change them in the Toggle Attribute Visibility dialog

  1. While in list view, select Settings settings. The Toggle Attribute Visibility dialog opens.

  2. Select the toggle next to each attribute to show or hide that attribute in list view.

  3. (Optional) If you want to show or hide all attributes, select Show All or Hide All.

    You cannot hide the Image ID.

  4. Select Apply.

Toggling attribute visibility affects only the selected catalog (i.e., selections for the archive catalog do not affect the online catalog).

List view allows you to see large amounts of image metadata in one place. You can sort the list by column to help you find imagery that fits your specific criteria.

  • To sort a column in ascending or descending order, select the arrow at the top of any column.

  • The active metadata field appears in yellow with an arrow to indicate sort direction.

    sort ascending applied

    Sorted in ascending order.

    sort descending applied

    Sorted in descending order.

When viewing archive imagery, sorting is limited to Acquisition Date, Cloud Cover, and Off Nadir Angle (both in the Sort By menu and when using sort arrows in the Imagery panel). This is a limitation of the Archive Discovery API.

Changing the sort order will re-render imagery in the viewport. This will likely change the existing stacking order (even if the Imagery panel was locked).

Use filters to narrow down your list even more. See Filtering Imagery.

You can also sort using the Sort By menu. For more information about all sorting options, see Sorting Imagery.
