Was this helpful?

Comments allow users to collaborate by attaching notes directly to specific locations on the map. Whether you're reviewing analysis, coordinating planning, or gathering feedback from teammates, comments keep the conversation tied to the data—exactly where it matters.

Each comment supports:

  • Threaded replies

  • @mentions to notify specific users

  • Direct links for easy sharing

  • Location and zoom-level persistence

Adding comments

Adding comments is simple and it has been designed to foster user collaboration:

  1. Locate the area of interest on the map.

  2. Click the Add comment button.

  3. Click on the specific point where you want to leave a comment.

  4. Type your message and press Enter to create a new comment thread.

Editor users can always comment.

Viewer users can comment too—but only if enabled by an Editor user in Map settings for viewers.

Comment notifications

When a comment is posted, an email is automatically sent to:

  • The map owner.

  • All participants in the thread.

  • Any @mentioned users — only if they already have access to the map.

Each email includes a direct link to the comment for quick access.

Resolving comments

  • Click Resolve to archive a comment in the Resolved view.

  • Click Reopen to bring it back to the active discussion.

Comments panel

The right-side Comments panel gives you full control over collaboration:

  • Real-time updates - new comments appear instantly both in the panel and directly on the map (no need to reload).

  • Search bar to find comments by keyword or author.

  • Unread indicators to track new threads or replies.

  • Filters:

    • All comments

    • Only unread

    • My comments

  • Visibility toggle to hide/show comments on the map.

Comment permissions

  • Only logged-in users with access to the map can add or reply to comments.

  • You can only @mention users who already have access to the map.

  • Anonymous users in public maps cannot view, post, or be mentioned in comments.

Comments on published maps

Comments are disabled by default on published maps. To enable them:

  1. Open the Map settings for viewers.

  2. Enable the Comments functionality.

Once enabled:

  • Logged-in Viewers with access can add and reply to comments.

  • Anonymous/public users cannot see or interact with comments.

Comments in Split View maps

Comments retain:

  • Latitude, longitude, and zoom level.

  • The side of the split view where they were added.

When switching views:

  • Split → Single view: You’ll be prompted to merge comment threads into the main view

  • Single → Split view: New comments will default to the left map.

Duplicating Maps

When you duplicate a map, existing comments are not copied. The new map starts without any comment threads.

Mark all as read functionality located at the bottom right corner allows you to mark all your comments as read.
