NGAD (Nuclear Guardian Against Disaster) v1.0 is a web browser-based system that uses GIS (Geographic Information System) maps to actively monitor the status of natural disasters, including wildfires, typhoons, earthquakes, and meteorological special reports.
When a natural disaster occurs, NGAD provides immediate situational awareness by displaying the disaster's location and meteorological information to the user. Critically, it visually represents the distance to key locations such as nuclear power plants, transmission lines, and transmission towers.

Enables organizations monitoring and controlling critical facilities to check real-time information related to disaster events.

The system generates immediate x-alerts when a natural disaster occurs near a major facility, ensuring users are instantly aware of the event.

NGAD collects natural disaster information via OpenAPI from government agencies, including the Korea Meteorological Administration and the Korea Forest Service. All collected disaster information is displayed on a GIS map.

When a wildfire occurs, the system displays the wildfire's location, especially those near major facilities, along with the distance to adjacent facilities.

Based on the Korea Meteorological Administration's ultra-short-term forecast, NGAD shows wind data for 3 and 6 hours from the current time, along with the distance from the wildfire to nearby major locations.

A wildfire x-alert message appears in a slide at the top of the screen, and a voice message is played. Pop-up windows provide the wildfire's start time, location, distance to adjacent facilities, and weather information.

Displays the typhoon’s scale, movement path, and projected path on the map.

An x-alert is triggered if major facilities fall within the typhoon's strong wind radius, both current and projected, after its formation. This x-alert also includes an audio message.

- Expected Typhoon Path Inquiry: Displays the most recent forecast path and allows users to view past forecast paths.
- Similar Typhoons Inquiry: Enables searching for past typhoons that followed a similar path to the current one.
- Past Typhoon Simulation: Provides a simulation function that shows the typhoon's position and path change over time after it formed.

Collects and displays information on earthquakes that occurred near major facilities, showing the location and distance from those facilities. Pop-ups provide the time, location, intensity, magnitude, and distance to nearby facilities.

When a weather advisory is issued, its details appear, and the affected area is shown on the map with an animation and an audio message plays.
