Building Information Modelling: essentials and issues: The need to Integrate BIM and Geoinformation

In the construction industry, business relationships are often short-term and one-off. There are many unique processes and activities. The resulting complexity and fragmentation may obstruct quick and effective exchange and integration of information and thus hamper project progress. Building Information Modelling (BIM) aims at preventing...

3D Indoor Models and Their Applications

Indoor environments are often referred as to enclosed spaces. However, the general definition of space can already indicate that a space can be bounded. Wordnet (http://​wordnet.​priceton.​edu) defines space as “an empty areas usually bounded in some way between things.”

Utilizing 3D building and 3D cadastre geometries for better valuation of existing real estate

Valuation of the properties is known as real estate appraisal, property valuation or land valuation and is a process which focuses on determining the value of a building or a land lot. The valuation of each real estate is required prior to any transaction as every property is unique in terms of shape, volume, location, orientation, quality and...

Semantically rich 3D building and cadastral models for valuation

The current valuation practices in various countries are analyzed: Turkey, United Kingdom, USA, Germany, and the Netherlands. The (possible) role of semantically rich 3D building models and 3D cadastres in relation to valuation and taxation is explored.

Semantically rich 3D building and cadastral models for valuation

Valuation of real estate/ properties is in many countries/ cities the basis for fair taxation. The value depends on many aspects, including the physical real world aspects (geometries, material of object as build) and legal/virtual aspects (rights, restrictions, responsibilities, zoning/development plans applicable to the objects spaces)....

Exploring the processes of generating LOD (0-2) CityGML models in greater municipality of Istanbul

3D models of cities, visualised and exploded in 3D virtual environments have been available for several years. Currently a large number of impressive realistic 3D models have been regularly presented at scientific, professional and commercial events. One of the most promising developments is OGC standard CityGML. CityGML is object-oriented model...

Standards for Exchange and Storage of 3D Information: Challenges and Opportunities for Emergency Response

3D standards have been developed throughout the years for many different purposes: visualisation (fast and realistic), data management (efficient storage), modelling (validity and topology) or data exchange (platform independence). The developers also vary from companies to international standardisation organisations that originated from CAD/BIM...

Sensor services for buildings: A framework and opportunities

The Ubiquitous Computing and the Internet-of-Things concepts are gathering more attention day-by-day. In the near future networks of interconnected sensors that are monitoring the environment around us will start to generate enormous amounts of data. This newly emerging paradigm can be named as „Sensors Everywhere”. This new paradigm will lead ...

IFC to CityGML Transformation Framework for Geo-Analysis: A Water Utility Network Case

The development of semantic 3D city models has allowed for new approaches to town planning and urban management (Benner et al. 2005) such as emergency and catastrophe planning, checking building developments, and utility networks. Utility networks inside buildings are composed of pipes and cables located between ceilings and walls (examples of...

A SWOT analysis on the implementation of Building Information Models within the geospatial environment

Building Information Models as product models and Building Information Modelling as a process which supports information management throughout the lifecycle of a building are becoming more widely used in the Architecture/Engineering/Construction (AEC) industry. In order to facilitate various urban management tasks (such as evacuation operations)...
