Abstract Dataset containing a Normalized Decorrelation Change Index used for deriving disturbances based on coherence information inside mine defined areas. Based on Sentinel 1 IW SLC data, the Index is computed using a temporal filter to reduce noise from the coherence information across the whole period, from 01/01/2015 till 01/10/2016. The temporal filtering is applied to ignore noisy data from Semptember till May. The values of the index are higher where decorrelations occured along the study period and lower where no relevant disturbances were identified. This depository contains data generated within the European S34 project. The data are in raw form and have not been further processed. Processed data are published in other depositories.
