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...
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...
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...
Spatial distribution density is an important constraint in map generalization, which acts on a group of objects at meso level or a whole thematic class at macro level. However, the spatial distributio...
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...
Delaunay triangulated irregular network (D-TIN) has been widely used in various fields and also played an increasingly important role on map generalization. But for massive data processing, current D-...
This paper is focused on applying digital map generalization into the updating of geo-spatial database from large scale in the collaborative updating environment for SDI, an updating production line...
