Abstract: A novel procedure for georeferencing raster images of the Third Military Survey maps from 19th century (1876-1880) is proposed in the contribution. There were several attempts to design a proper transformation model for georeferencing of these maps, but none of them have satisfactory resolved crucial problems of positional discrepancy between the old maps and contemporary maps. In the contribution, these problems are resolved with the aid of three approaches: huge number of control points, complex four-step nonlinear transformation procedure with easily tunable simple set of comprehensible transformation parameters, controlled accuracy propagation of an arbitrary transformed point. Due to these three unique features the positional accuracy was dramatically reduced.
