Data systems
The Finnish environmental administration has collected, stored and used environmental data since the early 1970s. The oldest data stored in our data systems start from about the 1850s.
Our data systems include a large amount of nationwide information, which is used for research, monitoring, control, planning, and assessments of the environment. At this time, not all of the database descriptions are available in English; those descriptions only in Finnish can be found via the link on the right.
The most important environmental data systems are the following:
Environmental Information System (HERTTA), which consists of various subsystems including information on, among other things, monitoring of water quantity and quality, environmental protection, biological diversity, land use and environmental loading.
Subsystems of HERTTA are:
The Compliance Monitoring Data System (VAHTI) which contains data on pollution loading, water and air pollution control, waste management and noise abatement.
Geographical Information Systems, which consists of over 50 nationwide GIS databases.
Direct access to environmental data systems through OIVA
OIVA - the environmental and geographical information service for experts - includes information on water resources, surface waters, ground waters, species, pollution and land use which the environmental administration has collected and stored in data systems. Additionally, OIVA includes a service to download the environmental and geographical information.
Registration and acceptance of the terms of use are required in order to use the service. The service is intended mainly for experts and the use of the service is free of charge.
