High resolution Sentinel-2 and Landsat-8 true-color images in the Tarkka service often load close-up when focusing. These images do not cover the entire area of Finland and the Baltic Sea on a daily basis, but areas about 200-300 m wide. Tarkka's background systems (interfaces of spatial data sets, interfaces of water quality data) will be tentatively updated during 2024 between approximately 3 pm and 7 pm on the following days: 26.3.2024 , 28.5.2024 , 1.10.2024 ja 26.11.2024.

New generation of Tarkka service was available since 1st June 2022.
