Xu, Longxiang (author), León Sánchez, C.A. (author), Agugiaro, G. (author), Stoter, J.E. (author)Nowadays, our society is in the transit to adopt more sustainable energy sources to reduce our impact on the environment; one alternative is solar energy. However, this is highly affected by the surroundings, which might cause shadowing effects. In this paper, we present our method to perform shadowing calculations in urban areas using semantic...conference paper 2024

Bachert, Carolin (author), León Sánchez, C.A. (author), Kutzner, Tatjana (author), Agugiaro, G. (author)With the increasing adoption of semantic 3D city models, the relevance of applications in the field of Urban Building Energy Modelling (UBEM) has rapidly grown, as the building sector accounts for a large part of the total energy consumption. UBEM allows us to better understand the energy performance of the building stock and can contribute to...journal article 2024

Agugiaro, G. (author), Pantelios, Konstantinos (author), León Sánchez, C.A. (author), Yao, Zhihang (author), Nagel, Claus (author)This paper introduces a new plug-in for QGIS that allows to connect to the free and open-source 3D City Database to load CityGML data, structured as classic GIS layers, into QGIS. The user is therefore not required to be a CityGML specialist, or a SQL expert, as the plug-in takes care of hiding from the user most of the complexity in terms of...conference paper 2024

Lehner, Hubert (author), Kordasch, Sara Lena (author), Glatz, Charlotte (author), Agugiaro, G. (author)This paper presents a CityGML-based data model developed for the semantic 3D city model of Vienna, Austria. The data model consists in a profile of the CityGML 2.0 standard and has been extended by means of an Application Domain Extension (ADE) developed by the Department for Surveying and Mapping of the City of Vienna in order to comply with...conference paper 2024

León Sánchez, C.A. (author), Agugiaro, G. (author), Stoter, J.E. (author)Current GIS software offer tools to perform the solar irradiance calculations. However, these computations based their work on data assumptions or generalisations to speed up their processing time. In this work, a method is shown to perform the calculation using very high and very low spatial resolution open datasets. The results show that there...conference paper 2023

Peng, Y. (author), Nijhuis, S. (author), Zhang, Guangting (author), Stoter, J.E. (author), Agugiaro, G. (author)This paper focuses on GIS-based visibility analysis to explore landscape architecture com-positions as a means to understand visual-spatial characteristics and identify related design principles. More specifically, the paper elaborates a practical method to employ high-resolution data acquired by terrestrial LiDAR (Light Detection and Ranging or...journal article 2022

Giannelli, D. (author), León Sánchez, C.A. (author), Agugiaro, G. (author)In this paper, five commonly used software tools to estimate solar radiation in the urban context (GRASS GIS, ArcGIS, SimStadt, CitySim and Ladybug) are run on the same test site and are compared in terms of input data requirements, usability, and accuracy of the results. Spatial and weather data have been collected for an area located in the...journal article 2022

(author)In the last 15 years semantic 3D city models have seen a steady growth in terms of creation and adoption. Many cities world-wide have now at least one city model which can be used for several applications. Energy- and sustainability-related topics are among those that have experienced a noteworthy increase of interest from the Geomatics...journal article 2022

Roy, E.I. (author), Pronk, Maarten (author), Agugiaro, G. (author), Ledoux, H. (author)Data on the number of floors is required for several applications, for instance, energy demand estimation, population estimation, and flood response plans. Despite this, open data on the number of floors is very rare, even when a 3D city model is available. In practice, it is most often inferred with a geometric method: elevation data is used...journal article 2022

Tufan, Ö (author), Arroyo Ohori, G.A.K. (author), León Sánchez, C.A. (author), Agugiaro, G. (author), Stoter, J.E. (author)3D city models are frequently used to acquire and store energy-related information of buildings for energy applications. In this context, CityGML is the most common data model, and the Energy ADE, one of its most complex extensions, provides a systematic way of storing detailed energy-related data in XML format. Contrarily, even though...journal article 2022

León Sánchez, C.A. (author), Agugiaro, G. (author), Stoter, J.E. (author)This document introduces the process for the creation of a testbed for energy applications based on a semantic 3D city model for the municipality of Rijssen-Holten in The Netherlands. The creation of this dataset requires the consolidation from multiple data sources as well as a lot of manual work so the authors can warranty as much as...journal article 2022

Widl, Edmund (author), Agugiaro, G. (author), Peters-Anders, Jan (author)Worldwide, cities are nowadays formulating their own sustainability goals, including ambitious targets related to the generation and consumption of energy. In order to support decision makers in reaching these goals, energy experts typically rely on simulation models of urban energy systems, which provide a cheap and efficient way to analyze...journal article 2021

León Sánchez, C.A. (author), Giannelli, D. (author), Agugiaro, G. (author), Stoter, J.E. (author)The 3D BAG v. 2.0 dataset has been recently released: it is a country-wide dataset containing all buildings in the Netherlands, modelled in multiple LoDs (LoD1.2, LoD1.3 and LoD2.2). In particular, the LoD2.2 allows differentiating between different thematic surfaces composing the building envelope. This paper describes the first steps to...journal article 2021

Dahle, F. (author), Arroyo Ohori, G.A.K. (author), Agugiaro, G. (author), Briels, Sven (author)In many countries digital maps are generally created and provided by Cadastre, Land Registry or National Mapping Agencies. These maps must be accurate and well maintained. However, in most cases, the update process of these maps is still done by hand, often using satellite or aerial imagery. Supporting this process via automatic change...journal article 2021
