摘要:The red mud disaster occurred on 4th October 2010 in Hungary has raised the necessity of rapid interventionand drew attention to the long-term monitoring of such threat. Both the condition assessmentand the change monitoring indispensably required the prompt and detailed spatial survey of the impactarea. It was conducted by several research groups - independently - with different recent surveyingmethods. The high spatial resolution multispectral aerial photogrammetry is the spatially detailed (highresolution) and accurate type of remote sensing. The hyperspectral remote sensing provides more informationabout material quality of pollutants, with less spatial details and lower spatial accuracy, whileLIDAR ensures the three-dimensional shape and terrain models. The article focuses on the high spatialresolution, multispectral electrooptical method and the evaluation methodology of the deriving high spatialresolution ortho image map, presenting the derived environmental information database.
