Agricultural monitoring of Russia using Remote Sensing: an overview
Savin I., Bartalev S., Loupian E. Some features of R&D at IKI
Focus is on national level (entire Russia) monitoring with application, if suitable, to sub-continental, or potentially, global coverage Primary sources of EO data are moderate resolution satellite instruments (mainly MODIS and SPOT-VGT), while resent developments in Russia are rapidly increase the potential role of high-res. (e.g. SPOT-HRV/HRVIR) data for national monitoring Focus on long-term time-series data analysis Development of automatic satellite data receiving and processing chains to perform monitoring in the routine and repeatable manner Sown area distribution in Russia

To extend arable lands map for entire Northern Eurasia region To develop operational mode for crop types mapping on entire Russia level To develop operational land-use change monitoring (e.g. land abandonment, aforestation, newly-ploughed virgin lands and etc.) To develop operational monitoring of risk of crop damage due to insects invasions (locusts, Colorado potato beetle…) To combine moderate and high-resolution satellite data to improve crop area estimated accuracy To introduce a new methods of crop yield forecasting based on crop growth modeling
