REMOTE SENSING FOR IRRIGATION SCHEDULING |
| Author: | B. Olivieri |
| Abstract:
The scheduling of irrigations based on remotely sensed data has not been, so far, fully realized. Many of the generally accepted data needs are not met by the currently handled remote sensing systems in terms of spatial resolution, time coverage, and real time availability. Furthermore, a rapid and precise analysis and interpretation of the acquired data sets demands more suitable models of the relationships between spectral data and crop and soil properties. This review introduces some basic ideas in remote sensing and gives some details about the major missions of some significance for hydrology. It focuses some points of concern in modelling the relations between soil moisture content, rainfall, evapotranspiration, and the reflectance data, stressing the role of surface dependent parameters such as roughness. It describes, in conclusion, the importance of the ground segment for: data processing, archiving, and dissemination to users. | |
