The process of gathering land cover information has evolved significantly over the last decade. In addition to this, current technical infrastructure allows for more rapid and efficient processing of large multi-temporal image databases at continental scale. But whereas the data availability and processing capabilities have increased, the production of dedicated land cover products with adequate accuracy is still a prerequisite for most users. Indeed, spatially explicit land cover information is important and does not exist for many regions. Our study focuses on the boreal Eurasia region for which limited land cover information is available at regional level.
