Integration of Hightech Components for Operating Ragweed Mapping and Control System in Hungary Using Remote Sensing and GIS

摘要

The Institute of Geodesy, Cartography and Remote Sensing (FOMI) has a 30 years programme and experience in the applications of remote sensing. The method-ology of the operational Crop Monitoring and Production Forecast Programme (CROPMON, 1997-2003) provided a basis for further applications development. One of the operationally proven programme components supports the ragweed control. The ragweed pollen induced allergy came an important issue in Hungary. It is at the point of a special kind of disaster and serious threat to the health of the citizen. Some 80 MEUR cost in medication annually is duplicated by the loss in the agri production. All these constituted a need for a National Ragweed Control Program revision. To the efficiency of this program, the government amended the plant protection law in 2005. This authorized the Plant and Soil Protection National Service to eliminate the infected areas immediately after their detection. In Hungary, some 500.000 – 700.000 hectare area is estimated to be strongly infected by ragweed. About 80% of this area can be pinpointed by remote sensing on the arable land. The development of remote sensing (RS) and GIS methods plus the GPS technology makes the tasks of the reconnaissance and in situ control more efficient. This system increases the success of the preventions of ragweed development. The system is a model for a range of integrated thematic applications of remote sensing. The four years' operational experiences in Hungary provide a realistic basis for adaptation.
