New Techniques and Methods for Modelling, Visualization, and Analysis of a 3D City

The recent years observe the vast development in new techniques and methods for modelling, visualization, and analysis of 3D digital cities, as the need of digital twins of urban environment in different applications and simulations has been increased dramatically. This special issue attempts to give an overview of the recent progress and...

3D Cadastres Best Practices, Chapter 3: 3D Cadastral Information Modelling

In this chapter we address various aspects of 3D Cadastral Information Modelling. Of course, this is closely related to the legal framework and initial registration as presented in the first two chapters. Cadastral data models, such as the Land Administration Domain Model, which include 3D support, have been developed for legal information...

Resolution in photovoltaic potential computation

In this paper, an analysis of the effect of the various types of resolution involved in photovoltaic potential computation is presented. To calculate solar energy incident on a surface, shadow from surrounding buildings has been considered. The incident energy on a surface has been calculated taking the orientation, tilt and position into...

The Possibilities of Using CityGML for 3D Representation of Buildings in the Cadastre

The main objective of the paper is to elaborate the possibilities of applying CityGML for cadastral purposes, drawing particular attention to the three-dimensional representation of buildings. Technical realization of the issue is executed at the conceptual level by integration the Land Administration Domain Model, officially published as an...

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)....
