Model validation of channel zapping quality

In an earlier paper we showed, that perceived quality of channel zapping is related to the perceived quality of download time of web browsing, as suggested by ITU-T Rec.G.1030. We showed this by performing subjective tests resulting in an excellent fit with a 0.99 correlation. This was what we call a lean forward experiment and gave the rule of...

Embedding 3D into multipurpose cadastre

There is no doubt that the cadastral map provides a useful entrance to information in a land parcel based information system. However, such information system could be made more meaningful and useful if it can be extended for multiple usages with multi data layers, and in three-dimensions (3D). Currently, many national mapping and cadastral...

3D Cadastre modelling in Russia

The paper presents the on-going project on 3D cadastre modelling in Russia. The aim of this project is to provide guidance in the development of a prototype and to create favourable legal and institutional conditions for the introduction of 3D cadastre modelling in Russia based on experience of the Netherlands and other countries. Among the...

World-wide inventory of the status of 3D cadastres in 2010 and expectations for 2014

In this paper, the background, set-up, and a preliminary analysis of the survey conducted by the FIG joint commission 3 and 7 working group on 3D-Cadastre, 2010-2014 is presented. The purpose of the survey is to make a world-wide inventory of the status of 3D-Cadastres at this moment (November 2010) and the plans/expectations for the near future...

The road to a standard land administration domain model, and beyond ...

The Land Administration Domain Model (LADM) is a Draft International Standard (ISO DIS 19152) and in January 2011 was distributed by the ISO central secretariat for a five month voting and commenting time interval. If everything goes as planned, ISO 19152 will be an International Standard (IS) by 2012. In this paper the road towards this...

Design of the 3D cadastre model and development of the prototype in the Russian Federation

This paper presents the on-going project on 3D cadastre modelling in the Russian Federation. The aim of this project is to provide guidance in the development of a prototype and to create favourable legal and institutional conditions for the introduction of 3D cadastre modelling in the Russian Federation based on experience of the Netherlands...

The final steps towards an international standard for land administration

The Land Administration Domain Model (LADM) moved forward to the FDIS stage (FDIS = Final Draft International Standard): ISO FDIS 19152. This is the last stage before becoming an International Standard (expected in July 2012), after a four year standards development process within ISO/TC211 (Geographic Information) and six years of preparation...

The 3D cadastre prototype and pilot in the Russian Federation

This paper presents the developed prototype and the planned pilot of the on-going project on 3D cadastre modelling in the Russian Federation. The aim of this project is to provide guidance in the development of 3D Cadastral registration and to create favourable legal and institutional conditions for the introduction of a 3D cadastre. The Russian...

Technology battles for complex systems: The influence of networks and standard flexibility

Most literature on standard selection focuses on compatibility standards for single products or large but single systems that are developing, such as the internet or a telecommunications network. In this study, we focus on systems that connect multiple existing subsystems and new subsystems to form a new complex system. We hypothesize that in...

ISO 19152:2012, LADM Expected Impact (abstract)

ISO 19152: 2012, Land Administration Domain Model published by ISO

This paper describes the last developments of the Land Administration Domain Model (LADM). The Final Draft International Standard, ISO FDIS 19152, unanimously passed on 1 November 2012 the final vote towards becoming an International Standard (IS). After technical editing by ISO secretariat in Geneve, Switzerland, the first edition has been...

Home Energy Systems: the State of the Art

Smart home energy systems are technically possible to realize but are not yet applied on a large scale partly due to the fact that no common standards exist that enable interconnection of components that make up these smart energy systems. Multiple standards have been developed which are competing in standards battles. In this paper we conduct a...

Towards an integration of GIS and BIM data: What are the geometric and topological issues?

Geographic information and building information modelling both model buildings and infrastructure, but the way in which they are modelled is usually complimentary and BIM-GIS integration is widely considered as a way forward for both domains. For one, more detailed BIM data can feed more general GIS data and GIS data can provide the context...

Committee III.2: Fatigue and Fracture

Concern for crack initiation and growth under cyclic loading as well as unstable crack propagation and tearing in the ship and offshore structures. Due attention shall be paid to the suitability and uncertainty of physical models and testing. Consideration is to be given to practical application, statistical description and fracture control...
