The revised Swiss Spatial Planning Act (RPG 2016) pursues the goal of inward settlement development to slow down urban sprawl and better protect arable land. This needs to be addressed in planning processes, as quality-oriented and sustainable internal densification is required. The Geodesign Framework by Steinitz is suitable for supporting such planning processes with public participation, where models and visualizations help to convey the complex systemic interrelationships to stakeholders. This paper presents a process model based on Geodesign that integrates GIS and Parametric Design, so that effects on internal densification caused by changes to building regulations can be quantified and communicated. In addition to an overview of the process model, selected results from its tests and verification are presented. The results suggest that the model approximates real interrelations well and is a suitable basis for further work.
修订后的瑞士空间规划法(RPG 2016)追求向内定居发展的目标,以减缓城市蔓延并更好地保护耕地。这需要在规划过程中加以处理,因为需要面向质量和可持续的内部致密化。斯坦尼茨的地理设计框架适用于支持公众参与的规划过程,其中模型和可视化有助于向利益相关者传达复杂的系统相互关系。本文提出了一个基于地理设计的过程模型,将地理信息系统和参数化设计相结合,从而量化和传达建筑法规变化对内部密度的影响。除了对流程模型的概述之外,还介绍了从测试和验证中选择的结果。结果表明,该模型较好地逼近了实际相互关系,为进一步的工作奠定了良好的基础。

Map-based discussion forums can be used for crowdsourcing people’s ideas and opinions with respect to public planning processes. Their volunteered geographic information consists of text and other media that are linked to geographic features. Building on the concept of argumentation mapping, Cartoforum was developed using the Boundless geostack, an open-source geospatial software package. We present the software architecture and functionality along with three pilot studies covering cycle lane planning in Toronto, Canada; community garden site-selection in the Toronto region; and campus sustainability at the University of Kerala, India. Together, the pilot studies demonstrate the utility of argumentation mapping and illustrate the range of its potential applications in citizen participation.

Movement data analysis is a high-interest topic in many scientific domains. Even though Python is the scripting language of choice in the GIS world, currently there is no Python library that would enable researchers and practitioners to interact with and analyse movement data efficiently. To close this gap, we present MovingPandas, a new Python library for dealing with movement data. Its development is based on an analysis of state-of-the-art conceptual frameworks and existing implementations (in PostGIS, Hermes, and the R package trajectories). We describe how MovingPandas avoids limitations of Simple Feature-based movement data models commonly used to handle trajectories in the GIS world. Finally, we present the current state of the MovingPandas implementation and demonstrate its use in stand-alone Python scripts, as well as within the context of the desktop GIS application QGIS. This work represents the first step towards a general-purpose Python library that enables researchers and practitioners in the GIS field and beyond to handle and analyse movement data more efficiently
运动数据分析是许多科学领域的热门话题。尽管Python是GIS世界中首选的脚本语言,但目前还没有Python库使研究人员和从业者能够有效地与移动数据进行交互和分析。为了缩小这一差距,我们提出了MovingPandas,这是一个新的Python库,用于处理移动数据。它的开发是基于对最先进的概念框架和现有实现(在PostGIS、Hermes和R包轨迹中)的分析。我们描述了MovingPandas如何避免在GIS世界中通常用于处理轨迹的基于简单特征的运动数据模型的限制。最后,我们介绍了MovingPandas实现的当前状态,并演示了它在独立Python脚本中以及在桌面GIS应用程序QGIS上下文中的使用。这项工作代表了通用Python库的第一步,使GIS领域的研究人员和从业者能够更有效地处理和分析运动数据

Designing user-friendly Public Participatory Geographic Information Systems (PPGIS) is a challenging task, since a PPGIS is typically used by users who have different characteristics and different requirements and needs. Hence, applying Human–Computer Interaction (HCI) principles is of particular importance in designing PPGIS. This study aims to create an inventory of usability aspects of a PPGIS by focusing on understanding the characteristics of a broad range of users. The usability study included 73 participants from Colombia, Uganda and Austria. We combined a custom qualitative survey (conducted in all three countries) with an eye-tracking based survey (conducted only in Austria). Considerable usability problems were faced especially by participants with low levels of IT-literacy. This was mostly due to a lack of experience in using functionally complex smartphone applications or interactive maps. In general, we observed a high level of difference in usability between the user groups. The eye-tracking statistics for the Austrian study supported the outcomes of the qualitative survey well.
设计用户友好的公共参与式地理信息系统(PPGIS)是一项具有挑战性的任务,因为PPGIS通常由具有不同特征和不同需求的用户使用。因此,应用人机交互(HCI)原则在PPGIS设计中显得尤为重要。本研究旨在通过重点了解广泛用户的特征,创建PPGIS可用性方面的清单。这项可用性研究包括来自哥伦比亚、乌干达和奥地利的73名参与者。我们将一项定制的定性调查(在所有三个国家进行)与一项基于眼球追踪的调查(仅在奥地利进行)结合起来。相当大的可用性问题,特别是对it知识水平较低的参与者。这主要是由于缺乏使用功能复杂的智能手机应用程序或交互式地图的经验。总的来说,我们观察到用户组之间的可用性存在很大差异。奥地利研究的眼动追踪统计数据很好地支持了定性调查的结果。

Under scenarios of urbanization coupled with increasing frequency and intensity of natural hazards, urban disaster risk is set to rise. Simulating future urban expansion can provide relevant information for the development of future exposure scenarios and the identification of targeted risk reduction and adaptation strategies. Here, we present an urban growth simulation for the coastal city of Monastir, Tunisia. The approach integrates local knowledge and a data-driven urban growth model to simulate urban sprawl up to 2030. A business-as-usual projection is used to predict the future growth of the city based on the historical trend. Thirteen Landsat images for the period 1975 to 2017 were used to delineate past changes in urban land cover following the European Urban Atlas standard, which served as the main input for the urban growth model. The simulation revealed that the city’s residential area is likely to grow by 127 ha to an overall size of 1,690 ha by 2030, corresponding to an increase of 8.1% compared to the urban footprint of 2017. The outcomes of the analysis presented here served as an input for the spatial simulation of future exposure to flash floods in the case study area.
在城市化的情况下,加上自然灾害的频率和强度不断增加,城市灾害风险必将上升。模拟未来城市扩张可以为制定未来暴露情景和确定有针对性的风险降低和适应策略提供相关信息。在这里,我们提出了一个突尼斯沿海城市莫纳斯提尔的城市增长模拟。该方法将当地知识与数据驱动的城市增长模型相结合,模拟到2030年的城市扩张。商业常规预测是根据历史趋势预测城市未来的增长。根据欧洲城市地图集标准,使用1975年至2017年期间的13张Landsat图像来描绘城市土地覆盖的过去变化,这是城市增长模型的主要输入。模拟显示,到2030年,该市的住宅面积可能会增加127公顷,达到1690公顷,与2017年的城市足迹相比,增长了8.1%。本文提供的分析结果可作为案例研究区域未来遭受山洪暴发的空间模拟的输入。

Replication of the Question-Based Spatial Computing Approach – Experiences and Suggestions for Further Developments 基于问题的空间计算方法的复制-进一步发展的经验和建议

Geographic Information Systems (GIS) have developed into complex toolboxes and require analysts to formulate spatial questions according to the requirements of data formats and tools provided by their GIS-application. The recently proposed language for spatial computing aims to provide a question-based and thus more comprehensible approach for spatial analyses that especially supports scientists and experts from other disciplines to conduct spatial analyses in their fields. In this contribution, we apply the question-based spatial computing approach to a case study in the humanitarian field and compare the resulting script to a script written with a conventional GIS tool. The comparison of the two versions of the analysis is based on six criteria covering qualitative and quantitative aspects of the analysis as well as the implementation concept behind the new language. Our results show, that the new approach requires fewer computational steps than the conventional script. In addition, the declarative approach lets users focus on the content of the spatial question and the query-like character of the language makes it in fact more comprehensible. Besides these benefits of the language for spatial computing, observations on challenges of the further development of the language are shared as an outcome of this study.
地理信息系统(GIS)已经发展成为复杂的工具箱,需要分析人员根据其GIS应用程序提供的数据格式和工具的要求来制定空间问题。最近提出的空间计算语言旨在为空间分析提供一种基于问题的更容易理解的方法,特别是支持其他学科的科学家和专家在他们的领域进行空间分析。在本文中,我们将基于问题的空间计算方法应用于人道主义领域的案例研究,并将结果脚本与使用传统GIS工具编写的脚本进行比较。比较两个版本的分析是基于六个标准,这些标准涵盖了分析的定性和定量方面以及新语言背后的实施概念。我们的结果表明,新方法比传统脚本需要更少的计算步骤。此外,声明性方法让用户专注于空间问题的内容,而语言的类似查询的特性实际上使其更易于理解。除了空间计算语言的这些好处之外,本研究还分享了对该语言进一步发展的挑战的观察。

Assessing Shrub and Tree Encroachment in Alpine Pastures from Airborne Laser Scanning Data 基于机载激光扫描数据的高寒草原灌木和乔木入侵评估
Q3 Social Sciences Pub Date : 2019-01-01 DOI: 10.1553/giscience2019_02_s73
Christoph Giger
The forest area in alpine regions is increasing. Agricultural land is abandoned; shrub and tree encroachment and reforestation are the consequences, with negative impacts on agriculture, biodiversity and tourism. Assessing encroachment on agricultural land from Airborne Laser Scanning (ALS) data was tested in three study areas in Switzerland. The results of the data evaluation were compared with those for manually collected data from the interpretation of orthophotos. The evaluation indicated that when a higher point density was available, the detection rate for areas with shrub and tree encroachment was also higher. The workflow using the Vertical Complexity Index (VCI) turned out to be robust for both large areas and large datasets. The accuracy levels achieved in this study for the encroachment index may provide a solid basis for prioritizing certain areas for projects that aim to limit the process of reforestation.
高寒地区的森林面积正在增加。农用地被废弃;灌木和树木的入侵和重新造林是其后果,对农业、生物多样性和旅游业产生负面影响。利用机载激光扫描(机载激光扫描)数据对瑞士三个研究地区的农业用地侵占情况进行了评估。将数据评价结果与人工采集的正射影像解译数据进行比较。评价结果表明,当点密度较高时,灌木和乔木入侵区域的检出率也较高。事实证明,使用垂直复杂性指数(VCI)的工作流对于大区域和大数据集都具有鲁棒性。本研究取得的侵蚀指数的准确度可以为限制再造林进程的项目确定某些地区的优先次序提供坚实的基础。

In this paper, we demonstrate environmental monitoring in a young citizen science project. The dynamics of urban tree phenology and microclimate regulation throughout the growing season is measured in a cross-city approach, along intraand inter-urban gradients and for a set of the most common urban tree species. We equipped urban trees in five European cities with beacons that connect via Bluetooth to a tailor-made app. The app is used for phenological monitoring, to display microclimate measurements, and to broadcast information on the trees' microclimate-regulating ecosystem services. The approach and setting are scalable to other citizen-engagement and VGI projects. It fosters an understanding of how urban trees are in sync with urban climate, and deepens our understanding of systemic feedback, which is key for implementing urban tree management. Results show inter-species differences in the length of the growing season as measures of the delivery of regulatory ecosystem services and as responses to urban heat island intensity.
在本文中,我们展示了环境监测在一个青年公民科学项目。通过跨城市的方法,沿着城市内和城市间的梯度和一组最常见的城市树种,测量了整个生长季节城市树木物候和小气候调节的动态。我们为欧洲五个城市的城市树木安装了信标,信标通过蓝牙连接到一个定制的应用程序。该应用程序用于物候监测,显示小气候测量结果,并广播有关树木小气候调节生态系统服务的信息。该方法和设置可扩展到其他公民参与和VGI项目。它促进了对城市树木如何与城市气候同步的理解,并加深了我们对系统反馈的理解,这是实施城市树木管理的关键。结果表明,物种间生长季节长度的差异是调节生态系统服务提供的指标,也是对城市热岛强度的响应。

Results show inter-species differences in the length of the growing season as measures of the delivery of regulatory ecosystem services and as responses to urban heat island intensity.","PeriodicalId":29645,"journal":{"name":"GI_Forum","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89778550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over recent years, unprecedented urbanization has fostered the rapid development of multi-storey buildings and infrastructure facilities, resulting in spatial and functional complexities in cities. Land and property information plays a vital role in a wide range of applications in land administration in rapidly growing cities. However, the current fragmented practice relying on 2D representation does not provide a reliable and accurate legal description of underground and aboveground properties as a foundation for evidence-based decisions in support of economic prosperity, human activities and public safety in urban areas. We propose a conceptual framework for 3D digital management of urban land and property information. The framework provides a foundation to federate various 3D models, validate their integrity, and analyse them for land administration. Using a case study of a multi-owned building located in the state of Victoria, Australia, this paper explores the practicality of the framework to support decision-making in building subdivision.
近年来,前所未有的城市化进程促进了多层建筑和基础设施的快速发展,导致城市空间和功能复杂化。土地和财产信息在快速发展的城市土地管理中的广泛应用中起着至关重要的作用。然而,目前依赖二维表示的支离破碎的实践并没有提供可靠和准确的地下和地上财产的法律描述,作为支持城市地区经济繁荣、人类活动和公共安全的循证决策的基础。我们提出了一个城市土地和财产信息三维数字化管理的概念框架。该框架为联合各种3D模型、验证其完整性以及分析它们以用于土地管理提供了基础。本文以澳大利亚维多利亚州的一栋多业主建筑为例,探讨了该框架在建筑细分决策中的实用性。
