New methods are needed to automate cartographic generalization. This article presents a
method for automating the displacement of vector data, called the constraint method. The …

Abstract Geographic Information Systems (GIS) are computer systems used for storing,
retrieving, analyzing, and displaying spatial data. Considering the spatial nature of many …

This study examines the effects of line simplification on the positional accuracy of linear
features. The goal is to quantify the relation between the level of simplification and the …

Cartographic generalisation is the process of simplifying a representation to suit the scale
and purpose of a map. As such, generalisation has always been a central part in map …

Positional accuracy of spatial data can be assessed by means of line-based methods. In this
work we develop an analysis of the following four methods: Hausdorff Distance, Mean …

Map generalization changes the semantics and geometry of map objects according to the
context defined by users. How to evaluate and ensure the quality of generalization has …

Since the late 1960's automated methods for map generalisation have been studied, but
thus far no comprehensive system has been achieved. This is due to the general complexity …

Le premier chapitre a introduit le contexte de la recherche, la problématique à surmonter
ainsi que les objectifs fixés et la méthodologie suivie. Ce présent chapitre trace une …

Few studies have systematically examined the effects of different possible generalization
methods on the products of GIS operations. In this paper the effects of generalizing a Digital …
