On the Use of GIS, GNSS and RFID Technologies in Modern Irrigation Systems

One of the stringent problems in Europe and worldwide is the moderate use of water resources for irrigation. This communication deals with the use of GIS, GNSS and RFID-UHF technologies to propose an intelligent moisture surveillance system for the agricultural crops. By using such technologies, the objective is to design a tool which can help the end user to decide when the best moment is and where to irrigate its agricultural crop. In this context, the authors are presenting a state-of-the-art of the already existing humidity measurement systems and highlight the advantages and the drawbacks of their proposed one. The correlation between the measured soil humidity and other geospatial attributes such as the topographic slope may be also important for the end user. An example of a humidity distribution map developed with theArcGIS tool will be also presented.
