RESUMO

The topographic representation of a terrain may be modeled through a digital elevation model. They may contain several errors, which cause uncertainty about the reliability of the data. Realiable use of elevation data requires that uncertainty be identified and removed. However, a critical problem is the fact that these errors can be caused by many different reasons for each generated digital elevation model, making their identification and correction very difficult
