Evaluation of Topological Consistency in CityGML [PDF]

open access: yesISPRS International Journal of Geo-Information, 2019
Boundary representation models are data models that represent the topology of a building or city model. This leads to an issue in combination with geometry, as the geometric model necessarily has an underlying topology. In order to allow topological queries to rely on the incidence graph only, a new notion of topological consistency is introduced that ...

Legal Requirement Analysis for 3D Cadastral Database Design

open access: yesTransactions in GIS, Volume 29, Issue 2, April 2025.
ABSTRACT The growing complexity of modern infrastructures and land ownership necessitates transitioning from 2D to 3D cadastral databases to manage rights, restrictions, and responsibilities (RRRs) effectively. Requirements collection and analysis are critical steps in gathering entities, relationships, and attributes to design a database.

A CITYGML EXTENSION FOR HANDLING VERY LARGE TINS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
Abstract. In addition to buildings, the terrain forms an important part of a 3D city model. Although in GIS terrains are usually represented with 2D grids, TINs are also increasingly being used in practice. One example is 3DTOP10NL, the 3D city model covering the whole of the Netherlands, which stores the relief with a constrained TIN containing more ...
