The paper describes some experiences and the methodology used for evaluation the vertical accuracy of data on the official (state) topographic maps. The vertical accuracy is an important element of quality 3D representation on the topographic maps in digital, as well as in analoguos forms. A comparative way of testing is usually applied for determining the vertical accuracy, namely the comparison of the measured values of topographic maps with "true" or "conditionally true" values (numeric data

To a large extent, the vertical accuracy of data and geomorphology (geographic) fidelity relief on the topographic maps is not always sufficient quality. The type of survey and how the matter affects the quality, or the geodetic control points are drawn precisely, where the accuracy of the contour lines is lower. However, the application of a new technology is changes the 3D visualization of terrain, thus increasing the vertical accuracy of data.
