Quantifying the Impact of NDVIsoil Determination Methods and NDVIsoil Variability on the Estimation of Fractional Vegetation Cover in Northeast China

Yanling Ding, Xingming Zheng, Kai Zhao, Xiaoping Xin, Huanjun Liu
2016 Remote Sensing  
Fractional vegetation cover (FVC) is one of the most critical parameters in monitoring vegetation status. Accurate estimates of FVC are crucial to the use in land surface models.  ...  Two NDVI soil determining methods were compared for estimating FVC. The first method used an invariant NDVI soil for the Northeast China.  ...  The authors sincerely appreciate the use of in situ FVC at the Hulun Buir site provided by the Virtual Laboratory of Hulunber Grassland Remote Sensing.  ...

Impact of Soil Reflectance Variation Correction on Woody Cover Estimation in Kruger National Park Using MODIS Data

Ibrahim, Balzter, Mathieu, Tsutsumida
2019 Remote Sensing  
Time-series of imagery acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) has previously been used to estimate woody and herbaceous vegetation cover in savannas.  ...  Here, woody cover is estimated over Kruger National Park (KNP) from the MODIS 16-day composite time-series data using dry season NDVI/SAVI images and applying NDVIsoil determination methods.  ...  Special thanks to National Aeronautics and Space Administration (NASA) for providing the MODIS data. Conflicts of Interest: The authors declare no conflict of interest.  ...

The Three-North Afforestation Program (TNAP), initiated in 1978 and scheduled to be completed in 2050, is the world's largest afforestation project and covers 4.07 × 106 km 2 (42.4%) of China.  ...  In addition to its direct impacts, the TNAP has enhanced people's awareness of environmental protection and attracted consistent attention and long-term commitment from the Chinese government to the restoration  ...  The coefficient of determination (R 2 ) and the root mean square error (RMSE) were used to determine the accuracy of the estimated maize yields in Northeast China (R 2 =0.74, RMSE=520.02 kg ha -1 ).  ...
