Urban And Environmental Planning

<p><strong>Abstract.</strong> Precise and comprehensive knowledge about 3D urban space is required for simulation and analysis in the fields of urban and environmental planning, city administration and disaster management. In order to facilitate these applications, geo-information about functional, semantic, and topographic aspects of urban features, their mutual dependencies and relations is needed. Substantial work has been done in the modelling and representation of above-ground features in the context of 3D city modelling. However, the belowground part of the real world, of which utility networks form a big part, is often neglected. Existing data models for utility networks are generally very domain-specific and, therefore, not suitable either. This paper describes a 3D data modelling approach for integrated management of below-ground utility networks and related above-ground city objects. This approach consists of manipulating first the structure of existing utility data in the commonly used Feature Manipulation Engine ETL software in order to make the data compliant to the CityGML Utility Network ADE data model. Subsequently, workspaces are created that take care of storing the CityGML data into the free and open-source 3D City Database, which has been extended in order to manage utility network data, too. Moreover, the research shows the suitability of the extended 3DCityDB to perform graph-based topological operations by means of the PostgreSQL pgRouting extension. Lastly, the results are visualized in typical GIS applications, e.g. QGIS and ArcGIS.</p>

Farm Buildings

Over the centuries, farm buildings, which accompany the development of agriculture, have played an important role in defining spatial and environmental planning. In some European countries in particular, these rural structures have been built based on traditional agricultural needs and typical land characteristics. Considering the land abandonment that has occurred over the last five decades, with farmers moving to more comfortable residences in neighboring urban settlements, historical farm buildings have often been abandoned, thus causing a leakage of the historical-cultural heritage of the rural landscape. Nowadays, open data and geographic technologies together with advanced technological tools allow us to gather multidisciplinary information about the specific characteristics of each farm building, thus improving our knowledge. This information can greatly support the protection of those buildings and landscapes that have high cultural and naturalistic value. In this paper, the potential of Geographic Information Systems to catalogue the farm buildings of the Basilicata region (Southern Italy) is explored. The analysis of these buildings, traditionally known as masserie, integrates some typical aspects of landscape studies, paving the way for sustainable management of the important cultural heritage represented by vernacular farm buildings and the rural landscape.

The Way

Before we parked cars—we parked trees. These ‘parked’ verges, supplanted by parking places during the 1900’s, now present opportunities in cities such as Oslo, looking to cultivate car free, climate resilient, liveable spaces. The prospect of re-parking street trees has a poetic quality, but is not without its challenges. A key feature of street trees are the way they connect, complement, and conflict with other entities across the full profile of the street section—from subterranean to skyline. It is this attribute, we argue, that makes street trees great infrastructural connectors: boundary agents through which urban space above and below ground can be comprehended, diverse practitioners connected, and the agency of street trees in the repository of the street section, foregrounded in urban development and design.

Urban And Environmental Planning

AbstractA major challenge for researchers and urban planning practitioners is how to obtain meaningful and influential contributions on urban and environmental planning activities from children and young people within the constraints of adult policy and practice. The key elements of this challenge concern traditional methods of communication between ‘experts’ and children and young people in rationalist planning settings, versus emerging research in relation to children's and young people's views and agency around civic participation. This article will address the work of a number of researchers and practitioners who have grappled with the inherent tenions of making planning practice and urban design more inclusionary, while facilitating and respecting children and young people's civic participation. This article also advocates the advantages and strengths of their participation in planning and urban design processes.With a focus on two exploratory programs developed by the authors in the Australian states of New South Wales and Victoria, this article will demonstrate how the sharing of knowledge and skills between planning and design professionals and children and young people can lead to more meaningful and influential contributions from them. The programs examined were informed by leading practice both in Australia and internationally, and have assisted to develop children and young people's sense of spatial competence, and their confidence and efficacy in their local environment, contributing ultimately to their wellbeing. They have also supported the establishment of youth leadership groups with the confidence and skills to contribute to ongoing local government urban and environmental planning activities.

Abstract We present Monte Carlo Physarum Machine (MCPM): a computational model suitable for reconstructing continuous transport networks from sparse 2D and 3D data. MCPM is a probabilistic generalization of Jones's (2010) agent-based model for simulating the growth of Physarum polycephalum (slime mold). We compare MCPM to Jones's work on theoretical grounds, and describe a task-specific variant designed for reconstructing the large-scale distribution of gas and dark matter in the Universe known as the cosmic web. To analyze the new model, we first explore MCPM's self-patterning behavior, showing a wide range of continuous network-like morphologies—called polyphorms—that the model produces from geometrically intuitive parameters. Applying MCPM to both simulated and observational cosmological data sets, we then evaluate its ability to produce consistent 3D density maps of the cosmic web. Finally, we examine other possible tasks where MCPM could be useful, along with several examples of fitting to domain-specific data as proofs of concept.
