Toxic wastes from the aluminum refinery "Ajkai Timfoldgyar Zrt" got into the river system of Hungary after a reservoir burst its banks. Károly Róbert College tasked Envirosense to acquire the first hyperspectral and Lidar imagery of the disaster area.

Károly Róbert College tasked Envirosense  to acquire the first hyperspectral and Lidar imagery of the disaster area affected by the toxic spill in Hungary. First ever "red mud" hyperspectral images in remote sensing history enable access to the area of contamination.

SPECIM´s AisaEAGLE hyperspectral system from the College has been chosen to provide the complete coverage of the territory with orthorectified imagery at 1m pixel resolution, taken over the period from October 10-12th, 2010. The ability to acquire more than 100 square kilometers of images daily with the know-how of Envirosense Hungary allows the authorities to meet their needs in just a few hours, after the image acquisition, processing and delivery of the data. Hyperspectral images of the disaster area will help determining the actual size and concentration of the pollution and to control the mud distribution, and their effects in plant and water systems.

Toxic wastes from the aluminum refinery "Ajkai Timfoldgyar Zrt" got into the river system of Hungary after a reservoir burst its banks, releasing a flood of some 1.1 million cubic meters of toxic residues on October 4. Kolontar, the village nearest the reservoir, was immediately engulfed by a torrent of red sludge. The next day, the Hungarian government declared a state of emergency in three regions, impacted by the toxic wastes spill: Veszprem, Vas and Gyor-Moson-Sopron. Hungarian authorities addressed to the European Committee on October 7 to activate the mechanism of civil protection.

Envirosense offered the in-flight operation, post-processing, field sampling and classification free of charge.
