Judul : ET Estimation of Agricultural Lands in Pietermaritzburg, South Africa using Satellite Images
Abstrak :

Evapotranspiration (ET) is one of the most important parameters in agricultural water management. The aim of this research is to estimate actual evapotranspiration using satellite imagery, by ET Index approach in Pietermaritzburg, South Africa, to monitor the agricultural water management in the area. Another aspect of this study is to test the performance and the applicability of the ET Index approach, as this is the first application of the approach closely to a southern hemisphere. NDVI and ET related information were derived using the combination of local weather data and the seven clear-sky Landsat 8 imagery for year 2015. The data availability of Landsat 8 implied some limitations of time-series monitoring of agricultural practice of this area in 2015, especially in summer season, due to the cloud availability. This problem might be avoided by more careful selection of study area. The derived preliminary ET estimation results reported in this paper seemed rational, and will be more carefully evaluated in future considering weather conditions and the land uses.
