Underground pipelines pose numerous challenges to 3D visualization. Pipes and cables are conceptually simple and narrow objects with clearly defined shapes, spanned over large geographical areas and made of multiple segments. Pipes are usually maintained as linear objects in the databases. However, the visualization of lines in 3D is difficult...

This paper focuses on 3D data structures supporting an alternative approach for creating 2D vario-scale maps. The smooth animated zooming functionality have lead us to investigate a volumetric representation of gradually changing vario-scale objects. In this paper, the principle of vario-scale maps with theoretical knowledge about 3D...

Depth-contours are an essential part of any hydrographic chart|a map of a water-body intended for safe ship navigation. Traditionally these were manually drawn by skilled hydrographers from a limited set of surveyed depth measurements. Nowadays this process of map making is shifted towards the digital domain, not in the last place because of the...

Hoewel variabele schaal datastructuren een mogelijke oplossing zijn om geografische gegevens op meerdere schalen consistent bij te houden en te ontsluiten (bijvoorbeeld via webservices), staat of valt een dergelijke oplossing met een goed uitgevoerd generalisatieproces. Om op kleinere kaartschalen te kunnen beschikken over lijnrepresentaties van...

Digitale kaarten worden tegenwoordig overal gebruikt van desktop tot mobiele telefoon en het gebruik is meer en meer interactief en gebaseerd op zoomen en pannen. Kaartgeneralisatie onderzoek kijkt naar generalisatie zonder vaste schalen (‘continue generaliseren’). Hoewel er een aantal eerste resultaten zijn (van Kreveld, 2001; Sester and...

A method for generating a vario-scale visual representation of n-dimensional objects (together forming a space partition) is presented comprising the steps of - generating a higher and a lower detailed n-dimensional object representation each comprising digital data representing objects by zones in said n-dimensional object representations, said...

This paper presents the problem of the current separate treatment of levels of detail in city models. We propose a solution, detail the main principles, and present our initial results on the approach. We conclude with work in progress and explain the benefits of our approach.

As explained in van Oosterom & Stoter (2012), the nD modeling approach allows us to include different aspects of geo-information in spatial modeling at a fundamental level, i.e. by treating these aspects as additional (geometric) dimensions. This paper explains how nD data models and data structures may solve the issues of redundancy and...

This paper presents the first true vario-scale structure for geographic information: a delta in scale leads to a delta in the map (and smaller scale deltas lead to smaller map deltas until and including the infinitesimal small delta) for all scales. The structure is called smooth tGAP and its integrated 2D space and scale representation is...

Although the validation of single polygons has received considerable attention, the automatic repair of invalid polygons has not. Automated repair methods can be considered as interpreting ambiguous or ill-defined polygons and giving a coherent and clearly defined output. At this moment, automatic tools are not satisfactory and repairing is thus...

The use of geo-information is changing by the advent of new mobile devices, such as tablet-pc's that harness a lot of computing power. This type of information is more and more applied in mainstream digital consumer products, in a net-centric environment (i.e. dissemination takes place via the Internet) and the advances in mobile hardware also...

This paper introduces the concept of a space-scale partition, which we term the space-scale cube – analogous with the space-time cube (first introduced by Hägerstrand, 1970). We take the view of ‘map generalization is extrusion of 2D data into the third dimension’ (as introduced by Vermeij et al., 2003). An axiomatic approach formalizes the...

In this paper, we will give a description of a design of a fat client and study some implementation issues, to use the tGAP structures for progressive data streaming. This is an experiment to validate the theory of Haunert et al. (2009). Furthermore this theory is extended and a solution is proposed to make the progressive data streaming more...
