Abstract
The most commonly used topographic vector data are currently two-dimensional. The topography is modeled by different objects; in contrast, a digital terrain model (DTM) is a continuous representation of the Earth surface. The integration of the two data sets leads to an augmentation of the dimension of the topographic objects, which is useful in many applications. However, the integration process may lead to inconsistent and semantically incorrect results. In this paper we describe recent work on consistent and semantically correct integration of 2D GIS vector data and a DTM. In contrast to our prior work in this area, the presented algorithm takes into account geometric inaccuracies of both, planimetric and height data, and thus achieves more realistic results. Height information, implicitly contained in our understanding of certain topographic objects, is explicitly formulated and introduced into an optimization procedure together with the height data from the DTM. Results using real data demonstrate the applicability of the approach.
