SplitArea: Een algoritme om vlakken te splitsen voor de tGAP datastructuren

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...

3D Cadastral complexities in dense urban areas

The current paper aims to study the multi-stakeholding urban area locations in Delhi and around where (infrastructural) changes are creating the complex land management situations for the authorities involved

Standards for new approaches

Th e new Land Administration Domain Model (LADM) has evolved as an ISO-recognised standard to provide a formal language for describing traditional land administration methods, spot the similarities and diff erences, and provide a way forward.

Transportation mode-based segmentation and classification of movement trajectories

The knowledge of the transportation mode used by humans (e. g. bicycle, on foot, car, and train) is critical for travel behaviour research, transport planning and traffic management. Nowadays, new technologies such as the GPS have replaced traditional survey methods (paper diaries, telephone) since they are more accurate and problems such as...

Variable-schaal geo-informatie [1]

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...

Maps4Science - National Roadmap for Large-Scale Research Facilities 2011 (NWO Application form)

The Netherlands is historically known as one of worlds' best-measured countries. It is continuing this tradition today with unequalled new datasets, such as the nationwide large-scale topographic map, our unique digital height map (nationwide coverage; ten very accurate 3D points for every Dutch m2) and a range of public and private collections...

Indoor Pedestrian Navigation Using Foot-Mounted IMU and Portable Ultrasound Range Sensors

Many solutions have been proposed for indoor pedestrian navigation. Some rely on pre-installed sensor networks, which offer good accuracy but are limited to areas that have been prepared for that purpose, thus requiring an expensive and possibly time-consuming process. Such methods are therefore inappropriate for navigation in emergency...

Progressive transmission of variable scale vector data over the web - more details on demand

Connectivity in the regular polytope representation

In order to be able to draw inferences about real world phenomena from a representation expressed in a digital computer, it is essential that the representation should have a rigorously correct algebraic structure. It is also desirable that the underlying algebra be familiar, and provide a close modelling of those phenomena. The fundamental...

3D cadastre in the Netherlands: Developments and international applicability

This paper presents the design and implementation of the cadastral system extension for registration of 3D rights and restrictions in the Netherlands fitting within the ISO 19152, Land Administration Domain Model (LADM) final draft international standard. The implementation will be conducted in two phases. The first phase of the solution does...
