Several ecosystems have been significantly altered by anthropogenic nitrogen inputs. The timely estimation of concentration is essential for ensuring environmental sustainability. Academic publications between 1966 and 2016 were reviewed to assess the potential remotely sensed information estimate concentrations various applications. A discriminatory keyword search a set inclusion criteria was ...

Evapotranspiration (ET) represents crop water use and is a key indicator of health. Accurate estimation ET critical for agricultural irrigation resource management. retrieval using energy balance methods with remotely sensed thermal infrared data as the input has been widely applied scheduling, yield prediction, drought monitoring so on. However, limitations on spatial temporal resolution avail...

There are significant issues and problems in the integration of remotely sensed data and GIS due to the differences in data characterisation, data structure and data processing philosophy between the two technologies. Difficulties exist particularly in handling large data volumes in GIS which are unavoidable when using remotely sensed imagery. This paper focuses on the integration of image data...
