High-resolution change detection
FORMOSAT-2 Satellite

FORMOSAT-2 is a high-resolution optical satellite able to revisit the same point on the globe every day in the same viewing conditions.
Its unique orbit and 2-metre resolution are well suited to change detection and rapid coverage of large areas.

Change detection

Changes in land occupancy and infrastructures are highlighted by comparing multi-date images. You specify how often you need to acquire imagery: daily, weekly or according to a regular cycle. Repeat imagery is acquired with the same viewing conditions and using the same parameters every time. Below is a sample of change-detection applications:

Airbus Defence and Space’s satellite-based monitoring service GO MONITOR
Monitoring the Arak nuclear plant in Iran Security and Defence
Monitoring areas hit by Hurricane Katrina in New Orleans Risk Management
Shipping movements in the port of Norfolk, USA Maritime Surveillance
Monitoring the mud volcano in Java, Indonesia Environmental Monitoring

Rapid large-area coverage

FORMOSAT-2 South Korea Coverage

With its 24-km swath and daily revisits, the FORMOSAT-2 can cover large areas in a matter of weeks.

For example, this mosaic of South Korea covers more than 100,000 with 270 scenes processed to obtain a uniform natural colour

A unique orbit

FORMOSAT-2 is unrivalled today in the civil high-resolution satellite market. Operating from its geosynchronous orbit, it revisits the same points on the globe within its coverage area every day. And because the orbit is also Sun-synchronous, each point is imaged under the same lighting conditions every time (9:30 a.m. equator-crossing time). The satellite completes exactly 14 orbital revolutions every day.
