Jozsef Gedeon, Developments in Terrain Surface Modeling
and simple modeling of terrain surface geometry is necessary for
dynamic stressing of vehicles as well as for the planning of off-road
transportation. It is advisable to convert to chaotic methods and
procedures in the measuring/recording and analysis process. IA faster
sampling is recommended than customary now. Substitution of a running
mean for the simple one is mandatory. It is possible to estimate
the proportion of random information to the deterministic one in
the record. The scale parameter gives correct conversion of spatial
spectra to time spectra necessary for input-output calculations.
Part of the spectrum problem is still open to discussions but the
present state of understanding, too, is giving correct practical
solutions. Field tests in Hungary have confirmed the advantages of
chaotic analysis and modeling.
