Long Term Soil Productivity study using very high spatial resolution imagery

Soil productive is critical to Earth surface vegetation management and monitoring with significant environmental and economic value. The human impact has played a very important role in agriculture and forest soil disturbances. In this study, very high spatial resolution multi-spectral imagery was investigated for its value and potential in soil treatment study. Individual tree height and DBH were retrieved from the imagery and was used to estimate the biomass, which is expected to be important indicator of ground soil treatment. Controlled ground experimental sites were used to validate the result and preliminary results have shown the biomass can't directly reflect the tree health condition. The normalized year difference would be a much better indicator for this study.
