Goal and objectives of the project

Model development of quantifying mangrove canopy  biophysical traits  based on radiative characteristics of remote sensing images for mangrove ecosystems monitoring.

Main results

Theoretical results: Establishing a scientific fundamental for quantifying mangrove canopy  biophysical traits based on radiative properties of remote sensing images
Applied results: Successfull development of a radiative transfer model for quantifying mangrove canopy biophysical traits, as well as providing an automated solution for mangrove forest cover classification using remotely sensed images.

Novelty and actuality and scientific meaningfulness of the results

- The cloud computing platform Google Earth Engine provides an automated solution for mangrove cover and changes monitoring, high performance of big spatial data processing, and straightforward transferability
- The radiative transfer model was first developed to estimate the biophysical mangrove canopy biophysical traits for mangrove forest health monitoring. The model may present high transferability and scalability to apply to different research areas.
- Combining these two methods brings a complete solution for mangrove monitoring not only by quality (biophysical properties, forest health) but also by quantity (forest cover, forest change).
