Neuro-fuzzy modeling for crop yield prediction
Neural Networks Neuro-Fuzzy Fuzzy Neural Networks
2015/8/20
The purpose of this paper is to explore the dynamics of neural networks in forecasting crop (wheat) yield using remote sensing and
other data. We use the Adaptive Neuro-Fuzzy Inference System (ANFIS)...
Monitoring crop growth conditions using the global water satisfaction index and remote sensing
water availability evapotranspiration crop growth
2015/8/20
Water availability is one of the limiting factors to crop growth in arid and semi-arid zones. Shortages of fresh water become very
serious for different regions of the world with important consequenc...
Estimation of crop water stress index in almond orchards using thermal aerial imagery
Crop Water Stress Index MASTER canopy vapor pressure deficit almond
2015/8/14
An important method for estimating Crop Water Stress Index (CWSI) is by measuring surface temperature of the canopy. A remote sensing method was used to estimate CWSI of an almond orchard in Paramount...
DETECTING CROP ROTATIONS IN CHINA USING AVHRR IMAGERY AND ANCILLARY DATA
Land use Crop Detection Classification Imagery Multitemporal
2015/7/29
The situation of cropland use in China is very complicated. In many areas, the cropland is used in multi-cropped ways. There is a
need for better information on the area and distribution of cropland...
