Recognition of open soil surface as a method of restoring agricultural land use maps in the Republic of Sakha (Yakutia)

In this paper the authors analyzed data from five different sources – topographic maps, land management materials, UAV survey, retrospective monitoring of soil and land cover, and recognition of open soil surface - to identify and involve abandoned arable land into agricultural circulation. The result of “on-ground” verification showed the different accuracy of the methods. Retrospective monitoring of soil and land cover provides the highest correctness, close to 100%. The combination of this technology with recognition of open soil surface, which allows cutting off unsuitable lands, can provide a solution for inventory arable land and introducing it into agricultural circulation.
