“…Further research and development could be done to insert the third dimension in terms of digital elevation models (DEM) and 3D building models (BIM) to get a better visualization of the renovation area throughout the time. With regard to climate protection measures in urban surroundings, the third dimension could help to calculate the potential of regenerative energy such as solar or photovoltaic on building or landscape surfaces and optimize the already installed facilities (Bruse et al 2015, Coors et al 2016).…”

Abstract. The German law concerning Urban Development Promotion (Städtebauförderungsgesetz; StBauFG) is an important component of the Building Law (Baugesetzbuch). It enables municipalities to be financially supported by the federal and provincial governments for promoting urban development in downtown areas being in need of renovation, maintaining historical centers, or enhancing the value of socially imbalanced areas. Therefore, the law plays an important role for the economical, ecological, social and cultural status of cities. If an urban renovation area is formally declared the reconstruction measures taking place there lead to an upgrading of the real estate land values. The present work contributes on one side to the initial phase for the declaration of an urban renovation area and on the other side to the final phase comprising the legal accounting procedure. At first, the city planners must document the urban status concerning the structure and quality of buildings, vacancy rate for housing and industry, road condition and numerous other urban quality and structure deficits. To acquire these data, the open-source GIS plugin QField serves as an appropriate and easy to handle tool installed on a tablet for the urban planners to collect the necessary data on-site. The planners can then easily assign defined qualities and states of the objects on a map or edit and comment new objects and attributes. Through automatic updating of these data in the PostgreSQL-database, an interactive map in QGIS will then be automatically created in Python. For the last phase, the legal closure of a declared renovation area, our work supports the analysis and modelling of the relationships in the Authoritative Real Estate Cadastre Information System ALKIS® in order to identify the property owners being charged a so-called balance payment for the upgrading of the standard land values resulting from the applied renovation measures. The work shows the high potential of the ALKIS® data being processed with open-source software like PostgreSQL, QGIS, and QField towards a more effective urban planning.

“…The model is flexible, taking into account different levels of detail (LODs), and it is modular foreseeing the potential coupling of Energy ADE with other ADEs. The Energy ADE is supported by several implementations and studies [15,[17][18][19], and it is established both in an XSD schema and UML class diagram (Fig. 4).…”

The Application Domain Extension (ADE) is a built-in mechanism of CityGML to augment its data model with additional concepts required by particular use cases. The goal of this paper is to provide an overview of the ADE mechanism and a literature review of developments since its introduction a decade ago. The discovery of publications found that currently there are 44 ADEs supporting a wide range of applications, but also application-agnostic purposes such as harmonisation with national geographic information standards. We hope this paper to double as a reference material for the developers of new ADEs.

“…Often these errors are not visible at the scale the datasets are visualised [18], and, as a consequence, practitioners are not aware of the problem. In most cases, these errors prevent us from using the datasets in other software and applications, see Nouvel et al [21], Steuer et al [28], and Bruse et al [8] for concrete examples. However, it should be noticed that, even for visualisation purposes, errors can be problematic since the shading/colouring of surfaces is often based on the orientation of their normals.…”

val3dity: validation of 3D GIS primitives according to the international standards

The validity of 3D primitives in 3D GIS datasets is often a prerequisite for using them in simulation and decision-making software, e.g. visibility analysis, noise pollution assessment, and energy estimation. However, while agreed definitions exist (in the international standard ISO19107), most software vendors ignore them and implement simpler 3D primitives, for instance by excluding interior boundaries in surfaces and/or solid. Such limitations prevent practitioners from exchanging and converting datasets, and thus to use these in other software and applications. I present in this paper val3dity, an open-source software to validate 3D primitives according to the international definitions of ISO19107. Practitioners can use it directly, without limitations: its code is freely available under the GPLv3 license, both binaries and a web-application are publicly available. It takes as input several formats (including the international standard CityGML), and outputs a report that helps users identify and understand the errors. I describe some of the engineering decisions supporting val3dity, and show that it can be used to validate real-world datasets.
