Motivation Scientists increasingly rely on intelligent information systems to help them in their
daily tasks, in particular for managing research objects, like publications or datasets. The …

This paper proposes an approach for data modelling in five dimensions. Apart from three
dimensions for geometrical representation and a fourth dimension for time, we identify scale …

The various levels of detail (LODs) of a 3D city model are often stored independently,
without links between the representations of the same object, causing inconsistencies, as …

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

An important aspect of a Dutch research project into usable (and well scaled) mobile maps
for consumers is presented: the development of an appropriate field-based usability …

Landscape metrics are quantitative indices that describe the abundant information about
landscape patterns and specific characteristics of the landscape composition and …

When users zoom in or out on a digital map, the map should change correspondingly to
present geographical information at proper levels. A way to help map users better keep track …

This paper introduces the concept of the smooth topological Generalized Area Partitioning
(tGAP) structure represented by a space-scale partition, which we term the space-scale …

Until now, road network generalization has mainly been applied to the task of generalizing
from one fixed source scale to another fixed target scale. These actions result in large …

This chapter summarises cartographic generalisation operators used to generalise
geospatial data. It includes a review of recent approaches that have been tested or …
