The Schwarzenberg is a mountain southwest of Tamsweg on the southern side of the Mur valley with an altitude of about 1780 m. A big mire complex with an extent of about 80 ha has developed in the summit region. The Mires of the Schwarzenberg became a Ramsar site in 2004.

Ortho-rectification of SPOT 5 was required due to the site's high elevation, and it proved very difficult to identify mires from the imagery. SAR data - sensitive to water - is being used to complement the analysis, with the team responsible planning to evaluate dry season SAR imagery for additional information.
