Editing a Project

Editing a project allows you to visualize your selected images, manually select new images, remove images that don't meet your needs, and stack the images to best meet your project requirements. You can edit a project immediately after creating it, or you can open a project in edit mode.

  1. On the side panel, select the Projects icon . The Projects pane opens.

  2. Select Manage Projects. The Projects dialog opens.

  3. Next to any project, select the Action Menu , then select Edit Project. The Project Edit pane opens.

  4. Select a cell using the cell locator grid.

  5. Expand the Imagery section. Select the checkboxes next to the images you want to include in the project. Clear the checkboxes next to the images you want to exclude.

    Select the checkbox at the top of the imagery list to select all of the available images on the page. Clear the checkbox to remove all of the selected images on the page. The pagination arrows at the bottom of the Imagery section let you navigate through multiple pages of imagery, if available.

  6. (Optional) Drag images in the list to rearrange their stacking order. Use the Choose Images dialog to compare imagery and select different imagery for the project (see Choosing Images).

  7. Select the next cell using the arrow buttons, or select a new cell using the cell locator grid. Make additional image selections for each cell in the project.

  8. To entirely replace your selections for the project, select Reset.

  9. To apply additional filtering to your project, select the Filter button.

    • Acquisition Date / Time of Day Date and time ranges for when the image was acquired.

      The time of day filter does not return mosaic imagery.

      Be sure to format date and time ranges correctly.

      • Acquisition Date Format (yyyy-mm-dd)

        • Use the calendar picker to automatically format dates.

        • Date formats such as dd-mm-yyyy are not accepted.

      • Time of Day Format HH:MM AM/PM

        • Time ranges must be entered manually.

        • You must include AM or PM. Enter a space between the time and AM or PM (e.g., 08:17 AM, 12:42 PM).

        • Time ranges must use 12-hour format. 24-hour format is not accepted.

      You will receive an error if you format a date or time range incorrectly.

    • Cloud Cover The maximum cloud cover percentage. (0%–50%)

      The cloud cover filter applies to the entire strip, not your area of interest. Using this filter may filter out strips that have good coverage over your area but are cloudy elsewhere.

    • Source The source(s) you want to use for the imagery.

      Third-party data sources will be available if they are turned on for your account.

    • Sensor Type Select the Maxar sensor(s). (Satellite, Aerial, Radar)

    • Content Type Selections depend on your subscription. Generally, select from mosaics vs. strips.

    • NIIRS The NIIRS value. (0–7.0)

    • Max GSD The maximum ground sample distance. (5m–30cm)

    • Image Bands Select one or more image band types.

    • Off Nadir Angle A range for the off nadir angle. (0°–60°)

    • Sun Elevation A range for the sun elevation angle. (0°–90°)

    • Target Azimuth A range for the target azimuth. (0°–360°)

  10. When are finished making changes, select Exit.

Project Edit Interface Overview

The Project Edit interface is slightly different depending on if you created a dynamic grid project (i.e., not aligned with the coordinate grid) or a coordinate grid project. Dynamic grid projects are centered within an arbitrary grid with 1-degree-size cells, while coordinate grid projects show the cell designations. The top left cell is active.

Project Edit Interface: Dynamic Grid

Project Edit Interface: Coordinate Grid

 

Name

Description

1

Cell Details

Provides information about the active cell.

  • Cell Gives the active cell identifier—dynamic grid cells are numbered A–KE horizontally and 1–120 vertically; coordinate grid cells use applicable identifiers.

  • Available Gives a count of possible images for the current cell.

  • Selected Gives a count of selected images for the current cell.

  • Coverage Calculates the fulfilled portion of the cell based on current selections.

Use the First, Previous, Next, and Last arrow buttons to move from cell to cell in the grid.

2

Cell Locator

The black square indicates the current cell. Hover over a cell to highlight it in the viewport. Select a cell to zoom to it and make it active.

3

Imagery List

Select the checkboxes for the images you want use in your project. Clear the checkboxes for the images you want to exclude. Only selected images are shown in the viewport.

For dynamic grid projects, clearing the checkbox for an image in one cell removes it from the project even if you selected it for a prior cell. For coordinate grid projects, each cell has a separate cell list, so selections for one cell do not affect the selections for adjacent cells.

Each change you make is automatically saved.

4

Move Selected Images to Top

Select this button to move all the images you have selected to the top of the Imagery list. Unselected images are moved to the bottom of the list.

5

Select/Deselect All

Select this checkbox to select all of the available images on the page. Clear the checkbox to remove all of the selected images on the page.

6

Image Menu

This menu also opens when you right-click an image, and includes the following additional options:

  • Remove from Selection Equivalent to unchecking the image in the image list.

  • Choose Images Opens the Choose Images dialog, where you can view all images beneath a certain spot, such as a cloud, and select or remove the images. See Choosing Images.

  • Copy Lat/Lon to Clipboard See Copying Latitude & Longitude Using the Cursor.

See Using the Image Menu.

7

Pagination Arrows

Navigate through multiple pages of imagery, if available. For cell-based projects, you can navigate through imagery for that cell.

8

Comments

Expand this section to see comments associated with a project. See Commenting on a Project.

9

Filter

  • Applying a more rigorous filter during your material selection process removes and removes images that do not match filter criteria.

  • Loosening a filter brings in additional images that match the filter criteria, but does not automatically select them.

  • Filters are not retained across editing sessions. If you save a project and edit it later, any images that were previously filtered out will be listed in your new editing session.

For dynamic grid projects, filtering applies to the entire project, not just the current cell.

The filters you set in the New Project Settings dialog are not reflected in the Filters dialog. To reset your project and start from scratch, with new initial filters, use the Reset icon.

10

Reset

Discards your selections and resets the project. All filters are discarded. However, new images that were added to the online catalog and that meets the criteria selected when the project was created will be included.

11

Actions

Export a shapefile of your project, and export comments. Additionally, users with the Large Area Download account configuration can create mashups. See Exporting a Project as a Shapefile, Commenting on a Project, and Creating Mashups from Project Imagery.

12

Exit

Closes the Project Edit interface.

13

Viewport

Your AOI is overlaid on an arbitrary grid of 1-degree cells (dynamic grid) or on the coordinate grid. Footprints for the selected images are shown with image dates up to zoom level 10; imagery displays at zoom levels 11 and higher.
