4- Conclusion and future plans
Multiscale mapping has got a lot of attention during the last years, thanks
to the growing interest in visual aspects of multiple representations. How-
ever surprisingly few works can be found that investigate relief representa-
tion as an element of multiscale maps. In this paper we presented
methodology that provides representation and generalization of relief on
multiscale hypsometric maps. Proposed database structure takes mapping
scales into account. Developed algorithm for DEM generalization proved
to be efficient in middle and small scales of mapping. It preserves major
relief forms, slope profiles and structure lines although not being free of
shortcomings. We also pointed out some rules of relief graphical represen-
tation in multiscale mapping environment.
We believe that the most promising area to improve our methodology is
the development and incorporation of real-time methods to control relief
representation not only in fixed set of scales but in any scale within map
scale range. This would lead to reduction of number of database LoDs,
truly scale-correspondent and continuously changing image detailisation,
and ability to interpolate symbology between scales.
