4 Conclusion

New requirements on always more superior altimetry map sources for needs of road
designing call (within more effective collection of altimetry data and their sub-
sequent elaboration) for suitable selection of the acquisition method. Using above
stated methods for acquisition of source materials for designing works and above all
their accuracy, 3D character and optimization of the designing works will enable to
suggest and create a real work, which will be both economical and ecological one.
