13.01.2017 07:42Sensitive observation data have undergone obfuscation including spatial aggregation so that precise locations and other sensitive information is not publicly available. The precise location, place names, dates, names of observers and other information may have been obscured or removed. Read more about sensitive observations.
Data may have a research embargo (usually 2–4 years), during which data may have been hidden or obscured as described above. Data producer-owners may have chosen to permanently obfuscate all or part of their data.
To gain access to non-obscured data, you may make a data request. Non-obscured data is also available to Finnish authorities
