In this
paper aspects of using various technologies as a topographic basis for creating
orienteering maps are discussed. As a result the technique of laser scanning is
introduced as a possible option. It is anticipated, that the availability of
laser scanning technique will increase the possibilities of creating
orienteering maps. In this context some detailed problems as the inclusion of
break lines, the automated derivation of contour lines, the derivation of land
cover (esp. vegetation) and the extend of the necessary field work are
discussed. As the result of laser scanning data acquisition a fundament for
modelling the general terrain geometry is delivered but semantic information is
mostly missing. Therefore our proposal for a general workflow is discussed in
this paper. Demonstrated by an example a
workflow of including laser scanning technology into the orienteering map
production is shown. As a result the advantages and limitations of for the
production of orienteering maps is analysed.
