The mission of the Siberian Earth System Science Cluster (Sib-ESS-C) is to provide a web-based infrastructure and comprehensive information products derived from Earth Observation that support environmental and earth system research in Siberia. The ZAPÁS project is closely linked to the SIB-ESS-C developments and uses its capabilities by integrating local and regional sclale forest resource maps and using the SIB-ESS-C land dynamics analyses tools.

After developing regional and local scale forest resource maps based on optical and SAR satellite data, all geoinformation products are now integrated in the SIB-ESS-C geoportal. The portal can be used to apply the so-called multi-resolution concept in earth observation. In the case of the ZAPÁS initiative, state and dynamics of forest resourcees can be assessed for the Central Siberian test region.

The complete set of EO-based forest resource maps related to biomass and forest cover tracking is accessable via the SIB-ESS-C Geoportal. The basic funcions are explained in a tutorial. To access the ZAPÁS products click on ZAPÁS in the Study Areas section of the Data Catalog.

Visualization of deforestation (red) and reforestation patterns (green) based on annual biomass maps derived from ALOS PALSAR (25 m mosaics provided by JAXA's Kyoto and Carbon Science Initiative). The example of the Sib-ESS-C visualization of two forest change maps indicate the state and dynamics between 2007 and 2010 of a massive Central Siberian deforestation area near the Angara River.
