Based on time series data of SPOT / VGT and DMSP / OLS, the built-up and non-built-up areas of countries in South Asia were extracted via the local support vector machine method. Accuracy assessment showed that Kappa coefficients were above 0.85 were achieved in 1998 and 2013. Based on built-up areas detected, the urban expansion of the eight South Asian countries and their major cities were analyzed...
Vegetation phenological dynamics is an indicator of plant response to climate regime. Various methodologies are developed to determine the timing of vegetation greenup and senescence using time series of remote sensing data, but most of them are used for forests. This paper presented a simple phenology model to identify wheat (Triticum aestivum L.) greenup onset date from SPOT/VEGETATION data. An...
