Abstract: Currently in Poland to a number of engineering problems is used digital terrain model (DTM) generated based on data from laser scanning, which provides adequately accurate but very large data sets. Such large datasets pose significant problems in many issues. This is often the need to reduce the DTM. The paper presents the results of analyzes carried out on the impact of the field on the accuracy of the DTM in its reduction. To carry out the analysis used an original method for evaluating the accuracy of the numerical approximation of the land surface (Wysocki, 1998) and the method of prof. F.Ackermann on the assessment of the accuracy of the digital terrain model. Good convergence of the results obtained on the basis of both methods.The analysis has demonstrated the ability to reduce altitude information about the area for more than 90% without significant loss of obtained accuracy.
