The development of a sampling design is basic in environmental risk management plan. The aim of the present research is the environmental sampling design optimisation to monitor herbicides utilised in agriculture, combining remote sensing information whit other qualitative and quantitative data, managed in different format (raster, alphanumeric, vectorial. Remote sensing images can represent terrain surfaces of different nature and origin in a synthetic and uniform way. Using aerial-imaging the proposed method produced a map of soil classification, which allowed locating sources of risk and identifying main human and environmental targets exposed to risk. Then was applied the proximity analysis using information on position of the area and on other priori information. The output of this second step was the identification of homogeneous zones, where samples were collected.
The approach allows using remote sensing to overlap different informative levels in order to collect representative samples in large-size areas and provides a useful tool in the management of environmental risk.
