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.
