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

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)....

Semantic annotation of existing geo-datasets: A case study of disaster response in Netherlands

Use of relevant geo-information is one of the important issues for performing different tasks and processes in disaster response phase. In order to save time and cost, services could be employed for integrating and extracting relevant up-to-date geo-information. For this purpose, semantics of geo-information should be explicitly defined. This...

Shadow effect on photovoltaic potentiality analysis using 3D city models

Due to global warming, green-house effect and various other drawbacks of existing energy sources, renewable energy like Photovoltaic system is being popular for energy production. The result of photovoltaic potentiality analysis depends on data quality and parameters. Shadow rapidly decreases performance of the Photovoltaic system and it always...

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...

Monitoring the extent of flooding: Based on a case study in Queensland

“Of droughts and flooding rains” (Dorothea Mackellar 1885-1968, “My Country”). The recent flooding in Queensland affected rural areas, mines, towns and cities including the state capital. Tracking such an event on a day-by day basis raises practical and theoretical issues. While this year’s floods captured world headlines, there is a major...

Information management in civil engineering infrastructural development: With focus on geological and geotechnical information

In civil engineering infrastructural projects, information exchange and (re-) use in and between involved parties is difficult. This is mainly caused by a lack of information harmonization. Various specialists are working together on the development of an infrastructural project and are all using their own specific software and definitions for...
