This paper is an attempt to evaluate existing theoretical models for the accuracy of digital terrain models (DTM) both through a theoretical analysis and by experimental tests. In order to extend the discussion, some comments on the general form in which a DTM accuracy model should be constructed are also made and a possible solution is offered.
