Visualizing Cartographic Generalization

Map generalization is a complicated and not well-understood process. In order for users to go beyond the simple and arbitrary application of generalization operators, and accompanying tolerance values, to features in databases, visualization techniques must be designed to allow a better understanding of the effects. Through such visualization users can quickly understand, and adjust, their deci...

Knowledge Representation of Cartographic Generalization

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 records in database. Information that conducts user’s viewpoint to specific matter is a collection of facts or data. While knowledge exist in our brains which are the fusion of experience, information a...

Cartographic Generalization in Virtual Reality

This article describes the transposition of cartographic concepts to virtual reality (VR) applications. Versions of cartographic maps can be created by using Generalization. These versions can be implemented for VR applications using Levels of Detail. Cartographic Generalization is concerned with model visualization that uses twelve operators and domain-specific knowledge. There is no known tra...

How the Quality of Cartographic Generalization Is Assured – the Approach with an Automatic Cartographic Generalization Chain

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 developments worldwide have been concentrated on the efforts towards adaptive and easily embeddable automatic generalization modules or services. Based on an analysis of the common rules concerning the quali...
