The availability of efficient mapping systems to produce accurate representations of initially
unknown environments is recognized as one of the main requirements for autonomous …

For point clusters, the conflict and crowding of map symbols is an inevitable problem during
the transition from large to small scales. The cartographic generalization involved in this …

This paper presents an algorithm for point cluster generalization. Four types of information,
ie statistical, thematic, topological, and metric information are considered, and measures are …

In the typical nonparametric approach to classification in instance-based learning and data
mining, random data (the training set of patterns) are collected and used to design a …

This paper describes an approach for the typification of buildings using a mesh‐
simplification technique. The approach is adapted from the area of computer graphics and …

With a focus on mobile and web mapping, we propose several algorithms for on-the-fly
generalization of point data, such as points of interest (POIs) or large point collections. In …

In moving object visualization, objects and their attributes are commonly represented by
glyphs on a geographic map. In areas on the map densely populated by these objects …

提出了一个基于加权Voronoi 图的地图点群综合算法. 为点群中包含的统计, 专题,
拓扑和度量信息分别选定量化描述因子, 并把这些因子运用到点群综合过程中 …

In this paper, we examine three different measures of roughness based on a geometric
property of surfaces known as curvature. These methods were demonstrated using an …

One of the most frequent operations in mapping for mobile information services is the
conflation and portrayal of geo-coded thematic information with a topographic base map in …
