    Number Description
    1 Title of the Subscription. Generated manually by the Planet Account Manager.
    2 Subscription Description Description of the Subscription. Each Subscription generates a description that is designed to give additional information about what the Subscription is for.
    3 Date Filter. Choose the dates you wish to see. The dates you select must be within the Subscription start and end dates. 
    4 Toggle for Basemaps without Detections. There may be times where a Planet Basemap has zero detections. By default, the Analytic Feeds Viewer does not display these Basemaps, but you can toggle on the display of Basemaps without detections.  
    5 Results Sorting. Use this toggle to determine the order in which you wish to view results. Sort by date or number of detections.
    6 Number of Detections within the Image. The number of detections found within the image.
    7 Link to Explorer. Click this link to view imagery within the same AOI or that you have access to in Planet Explorer.
    8 Scene ID. This is the unique ID for the scene that was processed for the detection.
    9 Review & Export. Enables you to export detections as a geojson file. 
    10 Visualization Option: Heatmaps. Choose to see a heatmap of detectionsor each individual detection.
    11 Visualization Option: Individual Detections. Choose to see individual detections.
    12 Show all Time. This will toggle whether you see only detections for the selected time period or all time periods shown.
    13 Confidence Score Filter. Use the confidence score filtering feature to show bounding box detections with higher confidence and remove false positives with lower confidence scores.
    14 View Over Time. View how your area has changed over time and let Planet’s detections guide you to where the most change has taken place
    15 Confidence Score. A score (0 - 1.0) of how likely it is that this detection is a true positive (correct) detection
    16 Detection Diagonal Length. The measurement in m of the diagonal length of the bounding box detection. This can be a good proxy for object length.
    17 Image Acquisition Timestamp. The time at which the image was captured - this reflects the time that the object detected was present.
    18 Location. The Latitude and Longitude of the centroid of the detection.
    19 Link to Tasking Dashboard. Task a skysat to capture a high resolution image of the area. Note: You must already have access to the Tasking Dashboard

    Through the Review & Export flow, you’ll be able to quickly cycle through change detections shown on-screen, selecting the time period where you first see the change take place. After reviewing all detections, you’ll export the change detections into a clean dataset.

    Note: Your progress will not be saved once you leave the review flow. You’ll need to review all detections or export the entire dataset.

    Number Description
    1 Keyboard Shortcuts. Using the number keys, you can quickly select the time period which corresponds to when the change occurred.
    2 Progress Bar. You’ll see how many detections you’ve reviewed and how many more there are to go.
    3 Export All. You can bypass the review flow and export all detections
    4 No Change. Occasionally, you’ll run into false positive change detections - select “No Change” when you find a detection that doesn’t show change.
    5 Previous Detect. Go back to the previous detection
    6 Exit. Return to the main Feed Viewer display.
