Custom Vector Events (CVE) in the Platform

Tomorrow.io now supports the visualization of Custom Vector Events (CVEs) directly on the map. This allows users to instantly see high-impact weather and operational events from either public or private data feeds—no custom configuration required.

When to Use CVE Visualization

Use CVEs in the platform to:

• Display custom or premium weather event layers on the map
• View affected areas and asset overlap visually, in real-time
• Enable fast situational awareness without building your own data pipelines
• Explore feed-specific insight details directly from the map

What It Does

CVEs appear as interactive polygons on the map, drawn from pre-integrated vector feeds. When you click a CVE event, the side panel opens with detailed information, including:

• Feed name and description
• Severity and tags (if available)
• Linked insight (with name and description)
• Edit Insight option (if permissions allow)

CVEs are categorized into two types:

• Private CVE Feeds: Custom feeds configured for your account. Included at no additional cost.
• Public CVE Feeds: Curated feeds offered as premium data layers. For pricing, contact your Tomorrow.io Account Team.

Key Features

• Direct Map Integration: Toggle CVE layers from the Advanced Weather Overlays menu.
• Tooltip Descriptions: Hovering over a feed name displays its description.
• Grouped Layers: Private and public CVE feeds are clearly separated in the menu.
• Live Timeline Support: Events update dynamically based on the selected time.
• Insight Linkage: Some events may be associated with insights, accessible via the side panel.
• Monitoring and Alerts: Create location monitoring and alerts using supported CVE feeds as the weather trigger.

How to Access

1. Go to the Map page in the platform.
2. Expand the Advanced Weather Overlays icon.
3. Scroll to the Custom Vector Events section.
4. Toggle any CVE feed to visualize its events on the map.
5. Click any polygon to view event details in the side panel.

Monitoring and Alerts

You can use supported CVE feeds as the weather trigger when creating location monitoring and alerts.

When a monitored location intersects with a CVE event:

• The event appears in the Insights Timeline.
• Notifications are sent according to the configured alert settings.
• Monitoring follows the configuration of the selected CVE feed.

Event Information and Lifecycle

CVE events include additional information to help you understand why an event was generated and track changes over time.

Each event can include:

• Trigger values, such as the minimum, maximum, and average values that caused the event to be generated.
• Event ID, allowing you to identify and track the same event as it evolves over time.

Event Aggregation

CVE feeds support different event aggregation methods to match operational requirements.

Depending on the feed configuration, events can be generated as:

• Granular – Smaller, highly detailed events with minimal aggregation.
• Moderate – Balanced event aggregation for most operational workflows.
• Consolidated – Larger events covering broader geographic areas and longer time periods.

Note: The aggregation method is configured as part of the CVE feed and may vary between feeds.

Limitations

• Altitude filtering is not supported.
• Event aggregation is defined at the feed level and cannot be changed by end users.
• Monitoring and alerts apply to the selected feed as a whole; individual event types within a feed cannot be selected.
