Nadaoka Lab. - Analysis of visible and infrared characteristics of mangrove forests
The general aim of our research on mangroves is to utilize of remote sensing methods in the mangrove canopy characterization and to create a model of the mangrove forest reflectance. Specific objectives include:
- Identification of different mangrove canopy characteristic that are measurable from remote sensing systems
- Development of different remote sensing techniques that can be used to measure mangrove canopy characteristics
- Application of the canopy reflectance model in the interpretation of satellite imagery
- Quantification of the relative importance of parameters that govern reflectivity of mangrove canopies
- Measurement and field survey to supplement model needs
- Utilization of acquired remotely-sensed data to illustrate applicability and performance of the model
The figures below show the measurement approach and the results (Click to enlarge). Multidirectional reflectance measurements (left) were performed on a mangrove tree using a visible-near infrared spectrometer equipped with a tilt sensor and camera/video. This data is used to simulate the signal coming from a remotely-sensed data (right).
