Passenger aircraft offer a low-cost, high-frequency alternative for remote sensing in emergencies. This volunteered passenger aircraft remote sensing (VPARS) method uses volunteer-captured images for rapid disaster mapping, complementing satellite data.
Area of Science:
- Geosciences
- Remote Sensing
- Computer Vision
Background:
- Satellite remote sensing faces limitations in rapid disaster response due to low frequency, high cost, and cloud cover.
- Passenger aircraft present an alternative platform with high revisit rates, dense coverage, and lower costs.
Purpose of the Study:
- To introduce and validate a volunteered passenger aircraft remote sensing method (VPARS) for emergency response.
- To demonstrate VPARS's capability for rapid ground disaster mapping.
Main Methods:
- Utilizing images captured by volunteer passengers on commercial flights.
- Applying computer vision algorithms and geocoding for image processing.
- Employing multi-angle tilt images to mitigate cloud cover effects.
Main Results:
- Developed a VPARS method for emergency response applications.
- Successfully processed volunteer images into mosaic orthoimages for disaster mapping.
- Demonstrated effective cloud removal using multi-angle images in a case study.
Conclusions:
- VPARS offers a cost-effective and efficient complement to traditional remote sensing for emergency response.
- Frequent revisit times, dense coverage, and multi-angle imaging are key advantages of VPARS.
- The method shows significant potential for improving rapid ground change detection and disaster management.
