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