This paper reviews the methodological issues related to the integrated use of optical and radar satellite imagery in operational monitoring of boreal forests. Images from both Russian and foreign missions were used in the development of a dedicated treatment algorithm for tracking changes in forested areas caused by natural factors and human impact. A relevant land cover change database was created for the forested areas of the Khanty-Mansi Autonomous District, openly available online through a regional Centre of Spatial Services (CSS) geoportal. The developed system supports baseline and periodical surveys, and operational monitoring, with both qualitative and quantitative data on changes in forested areas. Our results can be used in land cover monitoring operations led by the regional divisions of the Federal Service for State Registration, Cadastre and Cartography (Rosreestr).
Keywords: operational monitoring, remote sensing, forest land, landcover change, radar data, processing algorithm, Rosreestr
