Advanced Remote Sensing, 2nd Edition

14.5. Synthesis methods of multisource data

Theoretically, forest AGB is directly determined by forest height, stand density, DBH, and species. How to make full use of multisource remote sensing dataset is an important topic.

After the field campaign and acquisition and processing of remote sensing and other environmental data, we have the biomass and corresponding imagery data over a set of points within a study area. Assume B _i , i   =   1, 2 ,…, N, is the biomass and X is the data vector. The biomass estimation is to find a prediction model F:

B ˆ = F ( X )

The objective of developing such model is to minimize ...
