GEOREFERENCING APPLYING WEIGHTING COEFFICIENTS FOR LEAST SQUARES METHOD ADJUSTMENT
Original language description
The article describes one of the problematic aspects of georeferencing old maps. It is the issue of weighting coefficients for ground control points. A certain number of ground control points always enters the transformation calculation. If global transformation methods are used, the adjustment applying the method of least squares is made in the case of a redundant number of ground control points available. The redundant number of ground control points always guarantees the check of the selection of these points. In the case that the standard positional deviation differs by an order, this point is suspicious and it should be eliminated from the calculation after the verification. The remaining ground control points vary by their different standard positional deviation. Ground control points should preferably be evenly distributed throughout the overall map drawing. The points are chosen on clearly identifiable objects on both the local and the reference map. The choice is always easier in urban areas. In rural areas, it mostly falls on road crossings, changes in the vegetation cover on land parcels or the confluence of rivers. These ground control points tend to have worse accuracy. The introduction of weighting coefficients is only suitable for global transformation methods.
