A method based on radiative transfer models (RTM) incorporating multi-angle data is used to estimate LAI. The estimation of LAI from inversion will be based on Look Up Tables (LUT) approach. The usefulness of the method was verified using the data of Spectral database of Chinese typical features. The determination coefficient R2 between estimated result and measurement data is high to 0.6046. The...
A virtual forest modeling approach using SRTM and TM data is proposed. L-systems (a plant modeling language) is used to create the coniferous and deciduous tree models with different LAI (Leaf Area Index) values. Output images of these tree models are planted on the 3D terrain built from SRTM data, via the image-based method of crossed-billboards. TM image pl93r026 is used to generate the land use...
Ocean primary production (OPP) is an important indicator of ocean ecological system. The spatial and temporal pattern of OPP is helpful for global climate change study. Remote sensing has the advantage of dynamic and large-scale information collection. Integration of remote sensing and ecological model is promising for OPP study. The aim of our study is to: 1) choose the suitable coefficient algorithms...
