The spatial soil database of the southern area of Ob River  in Tomsk Oblast is a set of spatial and attribute database in MapInfo. The spatial database was created by tracing of soil maps on paper and contains information on the territory of 22,000 sq. km. There are Tomsky, Krivosheinsky, Kozhevnikovsky and Zyryansky districts of the Tomsk Oblast incledes in database.
