Abstract

Mining waste is becoming one of the major issues in environmental management. Continuous monitoring is essential to ensure proper remediation activities. Polarimetric radar plays an important role in providing useful information about the conditions of tailings in cloud-prone areas such as Indonesia. This paper discusses the possibility of monitoring the wetness of tailings in the deposition zone, in order to support land reclamation. We discover that an acceptable level of accuracy is provided by a Mahalanobis classifier on linear polarisation C- and L-band radar data. Taking into account the recent launch of the Envisat radar sensor, we assess the possibility of using partial polarimetric radar data. Interestingly, we attain comparable accuracies on quad and dual polarimetric data. It suggests that partial polarimetric data can be useful and efficient for this specific purpose.
