The paper describes the implementation of the 3D city model of the pedestrian area of Cosenza, which in recent years has become the Bilotti Open Air Museum (MAB). For this purpose were used both the data available (regional technical map, city maps, orthophotos) and acquired through several surveys of buildings and "Corso Mazzini" street (photos, topographic measurements, laser scanner point clouds). In addition to the urban scale model, the survey of the statues of the MAB was carried out. By means of data processing, the models of the same statues have been created, that can be used as objects within the city model. <br><br> The 3D model of the MAB open air museum has been used to implement a Web-GIS allowing the citizen's participation, understanding and suggestions. The 3D city model is intended as a new tool for urban planning, therefore it has been used both for representing the current situation of the MAB and for design purposes, by acknowledging suggestions regarding a possible different location of the statues and a new way to enjoy the museum.

The Smart Cities data and applications need to replicate, as faithfully as possible, the state of the city and to simulate possible alternative futures. In order to do this, the modelling of the city should cover all aspects of the city that are relevant to the problems that require smart solutions. In this context, 2D and 3D spatial data play a key role, in particular 3D city models. One of the methods for collecting data that can be used for developing such 3D city models is Light Detection and Ranging (LiDAR), a technology that has provided opportunities to generate large-scale 3D city models at relatively low cost. The collected data is further processed to obtain fully developed photorealistic virtual 3D city models. The goal of this research is to develop virtual 3D city model based on airborne LiDAR surveying and to analyze its applicability toward Smart Cities applications. It this paper, we present workflow that goes from data collection by LiDAR, through extract, transform, load (ETL) transformations and data processing to developing 3D virtual city model and finally discuss its future potential usage scenarios in various fields of application such as modern ICT-based urban planning and 3D cadaster. The results are presented on the case study of campus area of the University of Novi Sad.

This work presents a concept for heating demand and resulting CO2 emissions prediction based on a 3D city model in CityGML format in various scenarios under the consideration of a changing climate. In the case study of Helsinki, the Helsinki Energy and Climate Atlas, that provides detailed information for individual buildings conducting the heating demand, is integrated into the 3D city model using the CityGML Energy Application Domain Extension (Energy ADE) to provide energy-relevant information based on a standardized data model stored in a CityGML database, called 3DCityDB. The simulation environment SimStadt is extended to retrieve the information stored within the Energy ADE schema, use it during simulations, and write simulation results back to the 3DCityDB. Due to climate change, a heating demand reduction of 4% per decade is predicted. By 2035, a reduction of 0.7 TWh is calculated in the normal and of 1.5 TWh in the advanced refurbishment scenario. Including the proposed improvements of the district heating network, heating CO2 emissions are predicted to be reduced by up to 82% by 2035 compared to 1990. The City of Helsinki’s assumed heating demand reduction through the modernization of 2.0 TWh/a by 2035 is not achieved with a 3% refurbishment rate. Furthermore, the reduction of CO2 emissions is mainly achieved through lower CO2 emission factors of the district heating network in Helsinki.

The French collection of Plan-Reliefs, scale models of fortified towns, constitutes a precious testimony of the history of France. The aim of the URBANIA project is the valorisation and the diffusion of this Heritage through the creation of virtual models. The town scale model of Strasbourg at 1/600 currently exhibited in the Historical Museum of Strasbourg was selected as a case study. In this paper, the photogrammetric recording of this scale model is first presented. The acquisition protocol as well as the data post-processing are detailed. Then, the modelling of the city and more specially building blocks is investigated. Based on point clouds of the scale model, the extraction of roof elements is considered. It deals first with the segmentation of the point cloud into building blocks. Then, for each block, points belonging to roofs are identified and the extraction of chimney point clouds as well as roof ridges and roof planes is performed. Finally, the 3D parametric modelling of the building blocks is studied by considering roof polygons and polylines describing chimneys as input. In a future works section, the semantically enrichment and the potential usage scenarios of the scale model are envisaged.

This paper presents and discusses the results regarding the initial steps (selection, analysis, preparation and eventual integration of a number of datasets) for the creation of an integrated, semantic, three-dimensional, and CityGML-based virtual model of the city of Vienna. CityGML is an international standard conceived specifically as information and data model for semantic city models at urban and territorial scale. It is being adopted by more and more cities all over the world. &lt;br&gt;&lt;br&gt; The work described in this paper is embedded within the European Marie-Curie ITN project “Ci-nergy, Smart cities with sustainable energy systems”, which aims, among the rest, at developing urban decision making and operational optimisation software tools to minimise non-renewable energy use in cities. Given the scope and scale of the project, it is therefore vital to set up a common, unique and spatio-semantically coherent urban model to be used as information hub for all applications being developed. This paper reports about the experiences done so far, it describes the test area and the available data sources, it shows and exemplifies the data integration issues, the strategies developed to solve them in order to obtain the integrated 3D city model. The first results as well as some comments about their quality and limitations are presented, together with the discussion regarding the next steps and some planned improvements.

<p>El propósito de este artículo es reflexionar críticamente en torno a la noción de paisaje y sus vinculaciones con modos -diferenciados y desiguales- de imaginar y habitar la ciudad. El análisis se sustenta en un estudio de caso en La Boca, un barrio de la zona sur de la Ciudad de Buenos Aires, donde confluyen procesos de reconversión urbana y déficit habitacional. Desde un abordaje etnográfico junto al uso de fuentes secundarias, el trabajo explora las principales características y transformaciones socioespaciales del barrio en relación con el resto de la ciudad. El artículo focaliza en prácticas de habitantes y usuarios, en diálogo con distintas aproximaciones al concepto de paisaje, y con estudios que destacan la relación entre una estetización de las ciudades contemporáneas y un modelo exclusivo de ciudad. Desde una perspectiva del habitar -centrada en las prácticas urbanas- el enfoque propuesto procura tomar en cuenta las tensiones e imbricaciones entre los paisajes urbanos cotidianos de sus habitantes y los paisajes culturales orientados a un consumo visual, incorporando en el análisis las relaciones desiguales de poder.</p><p><br /><strong>Abstract</strong></p><p><br />This article aims to critically reflect upon the notion of landscape and its links with -differentiated and unequal- ways of imagining and inhabiting the city. The analysis is based on a case study in La Boca, a neighborhood in the southern area of the city of Buenos Aires, where urban reconversion processes coexists with housing insufficiency. Through an ethnographic approach supplemented with secondary sources, the paper explores the main characteristics and socio-spatial transformations of the neighborhood in relation with the rest of the city. The article focuses in dwellers and passersby practices, in dialogue with different approaches to the concept of landscape, and with studies that emphasize the relation between the aestheticisation of the contemporary cities and an exclusive city model. From a dwelling perspective -centered in urban practices- the proposed approach seeks take into account the tensions and interweaving between the daily urban landscapes of La Boca’ s dwellers and the cultural landscapes oriented toward visual consumption, incorporating in the analysis the unequal power relations.</p>

This article explores ‘dialectical design dialogues’ as an approach to engage with ethics in everyday urban planning contexts. It starts from Paulo Freire’s pedagogical view (1970/2017), in which dialogues imply the establishment of a horizontal relation between professionals and amateurs, in order to understand, question and imagine things in everyday reality, in this case, urban transformations, applied to participatory planning and enriched through David Harvey’s (2000, 2009) dialectical approach. A dialectical approach to design dialogues acknowledges and renegotiates contrasts and convergences of ethical concerns specific to the reality of concrete daily life, rather than artificially presenting daily life as made of consensus or homogeneity. The article analyses an atlas as a tool to facilitate dialectical design dialogues in a case study of a low-density residential neighbourhood in the city of Genk, Belgium. It sees the production of the atlas as a collective endeavour during which planners, authorities and citizens reflect on possible futures starting from a confrontation of competing uses and perspectives of neighbourhood spaces. The article contributes to the state-of-the-art in participatory urban planning in two ways: (1) by reframing the theoretical discussion on ethics by arguing that not only the verbal discourses around designerly atlas techniques but also the techniques themselves can support urban planners in dealing more consciously with ethics (accountability, morality and authorship) throughout urban planning processes, (2) by offering a concrete practice-based example of producing an atlas that supports the participatory articulation and negotiation of dialectical inquiry of ethics through dialogues in a ‘real-time’ urban planning process.

As pesquisas elaboradas para compreender a urbanização desigual em Curitiba enfatizaram o papel do planejamento urbano nesse processo. Entendendo que essa desigualdade é resultado da forma como se dá a valorização da terra e da apropriação diferenciada desta pelas camadas sociais, torna-se necessário compreender como a prática do planejamento urbano se articula a essa dinâmica. Considerando que o avanço dessa discussão deve procurar revelar as causas dessa desigualdade, e não apenas constatar sua existência, este artigo tem como objetivo compreender essa relação a partir da análise de um caso específico: o Ecoville. Originalmente concebido como uma nova frente de expansão urbana que evitaria a ocupação de áreas impróprias na cidade, sua implantação ocorreu de maneira totalmente oposta, produzindo um espaço com baixa densidade populacional voltado para camadas de alta renda. Argumenta-se que o estudo do Ecoville contribui para construir uma explicação sobre a prática do planejamento urbano em Curitiba, porque evidencia as contradições que são produzidas em torno da valorização da terra. Palavras-chave: Ecoville; Curitiba; planejamento urbano; urbanização; valorização da terra. Abstract: In order to understand the uneven urbanization in Curitiba, previous researches have emphasized the role played by urban planning on this process. Believing that this urban inequality results from the manner that land values and ways of occupation by different social classes are established, it urges then to understand the work extent of urban planning on this dynamic. The goal of this article is to move forward the debate on this field by revealing the causes of this inequality, and not only assuming its existence, through the analysis of a specific case study: “Ecoville”. Originally conceived as a new urban front that would avoid settlement at improper areas within the city, its materialisation followed a totally opposed path, producing a low density development only suitable for upper classes. The research of this case study – “Ecoville” – helps to build an explanation of the urban planning practice in Curitiba, as it reveals the contradictions that stir around land values.

This paper presents an English case of urban agriculture, the Edible Public Space Project in Leeds, contextualised in a context of urban agriculture initiatives committed to social-environmental justice, to the reproduction of common goods and the promotion of an urban planning which promotes the right to food and to the construction of urban space from the bottom up. The case study emerged as the result of action-research at the crossroads between urban planning policies, community work and critical geography. As opposed to many similar initiatives, the Edible Public Space Project is not intended merely as a temporary initiative hidden within the tiny folds of the city, but rather as an experiment which imagines and implements alternatives to current forms of urban planning within those folds and it contextualises them in the light of the ecological, fi nancial and social crisis of the last decade.

Back in 2007 the municipality of Frederikshavn in Northern Jutland in Denmark decided to use only 100% renewable energy for electricity, heat and transport by the year of 2015. Frederikshavn, the largest city in the municipality, was naturally chosen as case city. To be able to verify whether the green energy balance is possible to achieve, it was necessary to create energy scenarios for the whole city and also give the possibility to alter the current energy production and consumption. At the same time the city decided to involve as many people living in the city as possible, making it a project for the citizens of Frederikshavn. One result of this decision was an interactive Web application developed at Aalborg University. The application uses a 3D city model of the city of Frederikshavn as interface and gives the possibility to alter inputs for the energy consumption and energy production of the city using sliders and buttons as part of the interface. While the 3D model gives an immediate visual result, a connection to an underlying numerical energy model developed in earlier years at the University delivers a quite precise calculation on all vital data involved in the overall calculation of renewable energy within a closed energy system. This chapter describes the underlying theories and methods for creating such a system and presents the system, which can be understood as a case story among many.

The rapid increase in applications of Light Detection and Ranging (LiDAR) scanners, followed by the development of various methods that are dedicated for survey data processing, visualization, and dissemination constituted the need of new open standards for storage and online distribution of collected three-dimensional data. However, over a decade of research in the area has resulted in a number of incompatible solutions that offer their own ways of disseminating results of LiDAR surveys (be it point clouds or reconstructed three-dimensional (3D) models) over the web. The article presents a unified system for remote processing, storage, visualization, and dissemination of 3D LiDAR survey data, including 3D model reconstruction. It is built with the use of open source technologies and employs open standards, such as 3D Tiles, LASer (LAS), and Object (OBJ) for data distribution. The system has been deployed for automatic organization, processing, and dissemination of LiDAR surveys that were performed in the city of Gdansk. The performance of the system has been measured using a selection of LiDAR datasets of various sizes. The system has shown to considerably simplify the process of data organization and integration, while also delivering tools for easy discovery, inspection, and acquisition of desired datasets.
