pgRouting library provides functions to compute shortest path between any two points of a road network which is of great demand and also a topic of interest in the field of GIS, graph theory and trans...
Road generalization is not only helpful to simplify complicated road networks but can also satisfy the needs of reasonable display of roads under varying scales, thus offering basis for updating and g...
In this study, we first develop a hypothesis that existing quantitative visual complexity measures will overall reflect the level of cartographic generalization, and test this hypothesis. Specifically...
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 ...
Generalization is the task of producing multiple maps, of a different scale or purpose, from a single detailed data source. The field of generalization can be split into model generalization and carto...
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...
It is one of the important ways for GIS data updating based on map generalization. This paper analyzes the main steps for road data updating based on map generalization. As the core of this updating p...
As the Geospatial Technology (GT) grows, the generation and utilization of 3D city spatial model are actively studied. In some applications, the fundamental model is too detail comparing with the leve...
In this paper we present an approach realizing the integration of data sets of different origin and with different resolution levels. The underlying idea is to reveal semantic correspondences between ...
This paper describes an animation for multi-scale representation of spatial data. More specifically, morphing technique is employed to animate the operations for the geometric transformations in digit...
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...
Street network vector data is represented as Regular Closed Network. The combinatorial structure of the Regular Closed Network is modelled through abstract cell complex. Two abstraction operators and ...
As one of the key techniques in multi-representation database, GIS, mapmaking and Digital Earth, automatic cartographic generalization has been intensively researched since decades. Current developmen...
Automating the map generalization process has traditionally been a major focus of research in cartography and GIS environment, even though a usable holistic generalization method is still lacking. The...
