Release Notes

Stereo Pairs

You can now search for and view stereo pair imagery in Discover. Stereo imagery products are designed for users with advanced image processing capabilities and photogrammetric tools. This product is ideal for Digital Elevation Model (DEM) generation, 3D visualization and feature extraction applications. Stereo images are collected in-track, meaning on the same orbit, and are acquired at angles optimal for stereo viewing and manipulation.

To view stereo pair imagery, draw an area. From the Product drop-down, select Stereo Imagery. If stereo imagery is available in your area, it will display in the Imagery panel.

See Overview: Imagery Panel.

Vivid Mosaic Imagery

You can now view and order Vivid Mosaic imagery in Discover. Vivid Mosaics is a suite of high-resolution, high-accuracy imagery basemap products, available off the shelf. From metro to global scale, Vivid Mosaics offer solutions to meet a range of customer needs and budgets.

To view Vivid Mosaic imagery, draw an area. From the Product drop-down, select the Vivid Mosaics product you want to view. If Vivid Mosaic imagery is available in your area, it will display in the Imagery panel.

See Viewing Vivid Mosaic Products.

Apps Icon

If you have access to Discover, you can now use an Apps icon in the bottom-left corner of the Discover interface to quickly access other tools, such as the developer portal and Discover.

See Overview: Interface.

Area Cloud Cover

Area cloud cover is now the default cloud cover metadata value when viewing image results in the Imagery panel.

Area cloud cover indicates the amount of cloud cover for an image strip within the selected area, while image cloud cover indicates the amount of cloud cover over the entire image strip. Depending on the size of the area and the location of each image strip in the area, the area cloud cover and image cloud cover percentages for each image strip may be very different, or they may be identical.

In this example, the image cloud cover is only 13%, but the area cloud cover is 77%.

See Filtering Areas.

Export All Areas and Copy Area Details

You can now use Discover's area export tool to export all areas at once to a GeoJSON, KML, or a Shapefile. Exporting one or more areas lets you save your areas so you can upload them again at a future time, or share them with someone else.

You can also copy the details of a single area or all of your areas to the clipboard, and then paste them into another document or program. This functionality does not technically "export" the area(s), but it does allow you to easily copy details like the area name, catalog ID, and size to the clipboard.

See Exporting Areas.

Multiple Image ID Search

You can now search for multiple image IDs at the same time using the Imagery panel. If you search for one or more image IDs, and the image(s) is found, an area is drawn around the image(s) and it is added to the search results. Each found image is added as a separate area. Expand any area to view the image and its metadata.

See Searching.

Open Data Enhancements

Enhancements have been made to the Open Data feature. The most notable enhancement is that all Open Data events are now visible without having to log in to Discover (however, you will need to log in to access event data). The subscription feature, which is no longer in use, has been replaced with social media icons. Some language clarifications make the Open Data feature easier to use and understand.

See Open Data.

Product Drop-Down

A Product drop-down has been added to the Imagery panel. The Product drop-down is a type of filter for the product categories that should display in the Imagery panel (e.g., core imagery, stereo imagery, Vivid Mosaic imagery). Core Imagery is selected by default. When changing product types, your filters and selected images are saved.

See Set Default Filters: Imagery Type Drop-Down.

Filter Updates

Several enhancements have been made to the filter functionality in Discover. These include:

• Global Default Filters and Area Filters You can now create search filters globally as well as for individual areas.

  • Global Default Filters These settings are inherited by all areas, including any new areas that you create.

  • Area Filters These settings apply only to the selected area and override global default filter settings.

    If you change area filter settings, global default filters are turned off. When you make new changes to the global default filters, the global default filter changes overwrite any area filters that you applied to individual areas.

• High-Definition Eligible Imagery Only You can now filter your search results to only include high definition imagery.

  When you select High-Definition Eligible Imagery Only, the available ranges for GSD, Area Off Nadir, and Sun Elevation automatically adjust to ensure the best possible imagery results.

  • GSD ≤60 cm (i.e., 70cm not available)

  • Area Off Nadir 0° – 30°

  • Sun Elevation 15° – 90°

  Be sure to check your filter settings if you have previously made changes to these filters.

• Ikonos Imagery Imagery from Ikonos-02 is now discoverable in Discover. When creating a filter, select this sensor from the Imagery Source drop-down.

• Search by Catalog IDs Within an Area When adding an area-specific filter, you can now search by specific catalog ID(s) within the area.

See Filtering Areas.

Multiple Shapefile Import

You can now import ZIP files containing multiple shapefiles. These shapefiles will import as individual AOIs.

See Importing Areas.

Coordinate Entry for AOIs

You can now create a rectangular AOI using desired center point coordinates and specified length and width measurements.

See Adding Areas.

Area Upload: Simplified Geometries

Area upload now simplifies complex geometries. If an imported area has more than 1000 vertices, it is automatically simplified to comply with order standards (e.g., fewer than 1000 vertices, simple geometry, no holes, no duplicate vertices, no self-interections, no incomplete polygons, vertices >1m apart).

See Importing Areas.

Download and Export Enhancements

The following enhancements have been made to downloading/exporting imagery:

• You can now export an area with or without the related metadata. If you export imagery metadata, it is included as a separate file in the ZIP file. See Exporting Areas.

• If an area does not have 100% coverage, the unfulfilled portion of the area now displays in red. When you export an area that does not have 100% coverage, Discover automatically packages the unfulfilled portion of the area along with the complete area for reference. See Exporting Areas.

• You can now save browse imagery to your computer. Right-click the browse link and select Save Link As... to save the browse image. See Overview: Imagery Panel.

Guest Login Flow Removal

You now must be logged in to access all functionality within Discover. Create a free account using a simple self-registration process, then use your new account to log in.

See Registering for an Account and Logging In and Logging Out.

Image Selection Enhancements

You can now easily view imagery collected within the last 72 hours. This allows you to easily see if new imagery has been collected over your areas of interest (AOIs).

See Showing Recent Collects.

Imagery Panel Redesign

The Imagery panel has been redesigned to provide a better user experience and more logical flow.

There are three main parts of the Imagery panel:

1. Search and Filters, where you can search for imagery, set default filters, and define the imagery type you want to view;

2. Your Areas List, where you can view your current areas and create new areas;

   and

3. Area Imagery Results, an expanded panel where you can view imagery results for one area at a time. These results are visible as tiles or as a list.

See Overview: Imagery Panel.

Permalink Updates

Permalinks have been updated to support up to 100 AOIs and 50 images per AOI. Ordering of AOIs and names are preserved. When sending to SFDC/RCA, no more than 10 AOIs can be sent due to memory limitations.

See Sharing Sessions.
