So far, most spatial data infrastructures (SDIs) provide services for the generation of fixed-scale maps only. In a project funded by the German Ministry of Education and Science, the potential ...
The generalization operation should first make decision of object importance at geographic level, which relates not only to the geometric properties of independent object but also the other context ob...
As 3D city models are becoming available and attractive for consumer purposes in personal navigation systems or visualization applications, the hardware used to visualize these models changes from spe...
Institute for Photogrammetry (ifp), Universität Stuttgart, Germany Geschwister-Scholl-Str. 24D, D-70174 Stuttgart martinlike presentation. In this paper, a generalization algorithm is presented t...
In order to simplify the generalization of contour lines during the compilation of maps at smaller scales, an indirect method is put forward based on the generalization of the corresponding DEM first ...
This article presents a novel approach for the automatic generalization of 3D building models with regard to a cartographic 3D visualization. Here, the goal is not to render realistic, but rather visu...
With the development of the technique of multiple dimension GIS databases, the problem of the key-scale becomes an important technical problem. The paper presents a new method about how to determine t...
Data, information and knowledge are the three inseparable levels in info-flow. Data are a serial of descriptions of discrete facts and geospace from the ontological view, which are considered as recor...
Technological development in the field of map and spatial database generalization is very fast, following the trend from manual cartography to computer-based cartography. Map generalization is an int...
This paper introduces the author's work on the compression of vector geospatial data intended for transport on the Internet. WebGIS vector data format is shifting to ASCII code such as XML. In some ap...
Cartographic maps are representations of the Earth upon a flat surface in the smaller scale than it’s true. Large scale maps cover relatively small regions in great detail and small scale maps cover l...
In recent years, 3D models have been created of many cities around the world. Most of these models are, however, only used for visualization in web frontends or navigation systems. With the rapid prog...
