Accuracy of the new generation elevation models

New elevation models from the Czech Republic are produced using airborne laser scanning. These new elevation models achieve much higher accuracy than previous models whose accuracy is expressed in meters. Declared accuracy was subjected to verification in five selected locations. Despite some problems with accuracy, especially in areas of significant microrelief shapes, these models comply the declared accuracy and they are a major contribution in the field of geoinformatics and terrain analysis. So far conducted tests confirm declared accuracy of both models.
