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. More »
The two days ZAPÁS validation workshop started on Tuesday 14 May with a welcoming by Anatoly Shvidenko followed by a project status presentation given by Christian Hüttich. The Meeting aimed to prepare a road map for the next steps, in particular how to operationalize and implement developed methods, derive product validation information and prepare the task on terrestrial carbon accounting for Central Siberia.
The status of the available forest inventory was presented by Mikhail Korets. The inventory could be provided for all local test sites. It was stated that in some cases the old inventory is (probably) more accurate than the most recent update. Reasons could be that information was eventually transferred from old maps from the 70ies. The local scale mapping (methods and products) was presented by the FSU team. More »

One key objective of the ZAPÁS project (in close cooperation with the ESA project BIOMASAR-II) is the mapping and monitoring of growing stock volume at multiple scales. Different satellite data are being explored, for intance to track cover changes of the natural Taiga forest in the Krasnoyarsk and Irkutsk regions in Central Siberia. In the framework of the EU-Russia Space Dialogue data from the ESA ROSCOSMOS and JAXA Space Agencies are analyzed. After the first project year, the following data sourses are analysed:
- Very high resolution: RESURS DK-1 [5 m] (Validation)
- High resolution: ALOS PALSAR [25 m] (local to regional scale Growing Stock Volume mapping)
- Coarse resolution: ENVISAT ASAR [1 km] (regional scale Growing Stock Volume mapping)
The recently published book “Let’s embrace space” contains around 50 projects from thwe 3rd call of the FP7 SPACE research programm. Ongoing research projects covering topics from land monitoring, space propulsion, and space whether are introduced. The ZAPÁS project is included in Chapter 14 in part I Earth Observation - land monitoring. The 560 page book is available for download in the EU book shop.
Let’s embrace Space
A spatially consistent picture of forest dynamics in Central Siberia is provided with JAXA’s ALOS PALSAR 25 m orthorectified mosaic data. In the framework of the joint Kyoto & Carbon Science Initiative FSU cooperates with the K&C science team in order to improve global forest monitoring and forest disturbance mapping.
Using the ALOS PALSAR Mosaic data will be on step forward for area-wide forest monitoring, in particular in vast forests of Central Siberia. the video presented here shows a virtual flight over the siberian Irkutsk and Krasnoyarsk region along the Angara River as seen by the ALOS PALSAR satellite. The multitemporal RGB false color composite indicates SAR HH backscatter dynamics between 2008 and 2010. Blue and green colours indicate biomass loss in 2008 and 2009. Bright backscatter values indicate stable growing stock conditions.
As a key part of the ZAPÁS research network the recently launched web map serice provides access to the satellite data sets and thematic products as well as the study area locations developed within the project. Going beyond the visualization of the geographical distribution of forest biomass related maps, such as growing stock volume, forest cover and disturbances (e.g. fire and clear cutting), the map portal provides a toolset for various data analyses methods.
In particular, the web-based geo-spatial analyses functionatities aim at fostering the joint exploitation of Russian and European Earth Observation data, where new cross-validation approaches are possible to analyse up- and down-scaling effects of integrated data sets and products and finally to improve their overall accuracies.
A one-day field trip to the Bolshemurtinskoe local test sites was realized on 28 August together with FSU and and the Suchachev Intitute of Forest of the Russian Academy of Sciences (SIF-RAS). The field trip organized by SIF-RAS was aiming to validate the first set of local map products, such as forest biomass and disturbance maps. First reference data were collected for the validation of local mapping activities. More »
On August 22, a Workshop “Environment and Global Climate Change” within the joint German-Russian Project “Central Siberian Laboratory on Global Climate Change – Sib-Lab” was held at the Center for Grant-Oriented Activity, Siberian Federal University (SibFU). http://www.sfu-kras.ru/en/10764
The Workshop participation was represented by 46 researchers and PhD students from the Russian Federation (SB-RAS institutions and universities), SibLab project partners from Jena and Berlin, Germany and by exchange students from France as starting researchers. More »
