Abstract. The validity of information collections can be verified by their coherence, such as in the case of Volunteered Geographic Information. However, corresponding coherence theories of truth do not readily apply to collections of data if these consist of non-interpreted or virtually non-interpretable symbols, as is often the case with machine learning models and other black box systems. This paper argues why data-driven geography requires coherence theories, to then transfer the concept of coherence theories from the information to the data level. Finally, the relevant implications on the interpretation of data, especially in the context of black box systems and machine learning, are discussed.

Abstract. Current mapping tools are often not inclusive and cannot be used by all stakeholders of spatial planning processes. In a co-design process involving scientific researchers and co-researchers with different physical disabilities, the accessibility of existing collaborative mapping tools was assessed. Based on the requirements for an inclusive mapping tool that were derived from the assessment an existing open-source software was adapted and extended to better meet these requirements. The resulting prototype of an inclusive mapping application for digital maptables was then evaluated by the group of co-researchers. The aim of this inclusive tool is to support collaborative planning processes.

Abstract. The recent influx of remote and proximal sensing data provides new opportunities to understand environmental processes. A potential application of these datasets is to facilitate forestry operations. However, forest management decision-making through sensing techniques faces many challenges, partly due to the involvement of stakeholders with different knowledge levels and objectives. We present a virtual reality application developed for forest monitoring and assessment to address some of these challenges. First, a workflow for visualizing different sources of environmental sensing data is introduced to reconstruct digitally forest and terrain characteristics. Then, the VR experience is introduced in which users can observe, manipulate, and measure LiDAR-derived forest and tree models in immersive virtual environments. Finally, a heuristic expert evaluation to assess the overall user experience and the usability of individual application features is reported. We also gathered open-ended responses from domain experts to reflect on the potential and actual uses of the application in forest-related practices.

Abstract. Despite the availability of effective interventions malaria continues to be a major public health issue in Kenya, where young children and pregnant women are particularly vulnerable. In this study we examined the spatial distribution of malaria incidence and how this relates to the environmental conditions required for malaria in 2020. The Kenya Malaria Indicator Survey (N=11,549) for 2020 was used with the Local Indicators of Spatial Autocorrelation (LISA) method to determine spatial clusters of malaria and assess their significance as well as interventions in use. Climate data was used with a Fuzzy Overlay method to create malaria risk maps. The findings suggest that malaria incidence is not evenly distributed across Kenya, with some regions having higher rates of transmission and others having lower rates. High-rate clusters of malaria and high-risk areas of malaria transmission could benefit from increased vector control measures.

Abstract. The European spruce bark beetle (Ips typographus L.) is a major disturbance agent in Norway spruce (Picea abies (L.) Karst) forests in Europe and it is estimated that a changing climate will result in more severe outbreaks in the future. To reduce the risk of large outbreaks it is important to have methods that enable early detection of bark beetle attacks to help forest managers to prevent population build-up, e.g by sanitary cutting. Several studies have been devoted to early detection of bark beetle attacks with Sentinel-2 data with a focus on spectral properties and vegetation indices for early detection with pixel-based methods. In this study we explore the potential to use changes in variability between pixels in windows of different sizes (3×3, 4×4 and 5×5 pixels). We compute the coefficient of variation for four vegetation indices (NDVI, NDWI, CCI and NDRS) in a time-series of Sentinel-2 data during a bark beetle outbreak in Sweden that was triggered by a drought in 2018. The results indicate that CCI is the most promising index for early detection and that the variability between pixels increase in windows with attacked trees from late July when the main swarming was the second week of May.

Abstract. Access to homecare is paramount for the older population wishing not to move to retirement homes. In Zurich, the organization “Spitex Zürich” is the public homecare provider, allowing the older population to experience high-quality life at home through regular visits. A major factor for ensuring self-determined living for the older population consists of a detailed understanding of the spatial accessibility to Spitex locations. Therefore, this paper is concerned with applying four different FCA methods for assessing the spatial accessibility of Spitex homecare workers to people aged 65 + in Zurich through the road and bike networks. The modified-Huff-model-three-step-FCA method is found to be best suited for modeling potential spatial accessibility in Zurich. Spatial accessibility index values show similar geographical distributions regardless of transportation mode. The neighborhoods of Seebach and Hottingen are identified as regions with relatively low spatial accessibility. Our findings contribute to a better understanding of the interpretation and the measurement of spatial accessibility, thereby facilitating autonomous living for the older population residing in Zurich, ultimately increasing the inclusiveness of the city.
摘要对于不想搬到养老院的老年人来说，获得家庭护理是至关重要的。在苏黎世，“Spitex z rich”组织是公共家庭护理提供者，让老年人通过定期访问体验高质量的家庭生活。确保老年人口自主生活的一个主要因素是对Spitex地点的空间可达性的详细了解。因此，本文关注的是应用四种不同的FCA方法来评估Spitex家庭护理工作者通过道路和自行车网络对苏黎世65岁以上人群的空间可达性。改进的赫夫模型-三步fca方法最适合苏黎世潜在空间可达性的建模。空间可达性指数在不同交通方式下的地理分布相似。Seebach和Hottingen社区被认为是空间可达性相对较低的区域。我们的研究结果有助于更好地理解空间可达性的解释和测量，从而促进居住在苏黎世的老年人口的自主生活，最终增加城市的包容性。

Abstract. With the increasing use of social media, we can analyze digital data to gain insights into social and cultural aspects of landscapes and cities. The understanding of the existing cultural ecosystem services (CES) can help improve human life quality through proper planning and execution of plans. This study aims to locate CES produced by Estonian forests and urban green spaces using Flickr photographs. Quantitative analysis of Flickr photos identified hot spots within the study area and determined the suitable distance of CES accessibility. CES were categorized into four categories: recreation, sense of identity, aesthetic pleasure, and education. The results showed aesthetic pleasure and sense of identity were the most identified CES, while recreation and education were identified less. Factors such as population density, seasonal variation, biodiversity, accessibility, and facilities can impact the identification of CES. While social media data has limitations, combining qualitative research methods with surveys and questionnaires can provide a more well-rounded result. The findings can help stakeholders make better plans and management policies for Estonian forests and urban green spaces.

Abstract. Dasymetric mapping is a well-known technique when attempting to refine census data spatially and/or temporally. Existing approaches in micro-level census disaggregation make use of building areas or volumes in the mapping process. In an empirical error comparison it is shown that using additional address data rather than only building footprints or 3D models can substantially reduce dislocation of residential population. We propose the use of address points as a geometric representation unit for a more refined census disaggregation method in the future.

Abstract. In order to design better pan-scalar maps, i.e. interactive, zoomable, multi-scale maps, we need to understand how they are perceived, understood, processed, manipulated by the users. This paper reports an experiment that uses an eye-tracker to analyse the gaze behaviour of users zooming and panning into a pan-scalar map. The gaze data from the experiment shows how people look at landmarks to locate the new map view after a zoom. We also identified different types of behaviours during a zoom when people stare at the mouse cursor, or during a pan where the gaze follows a landmark while the map translates.

Abstract. We present the design and implementation of an empirical synchronous remote study for exploring the relation between spatial ability and performance on web-mapping services involving undergraduate University students; digital natives. The study exploits Spatial Thinking Ability Test to assess participants’ spatial ability and to reveal if and to what extent it is related to their ability to perform tasks on popular web-mapping services. Participants’ performance was assessed on the basis (a) of successfully executing tasks and (b) of how much time participants needed to properly perform tasks. A usability scale was used to measure participants’ subjective perceptions of web-mapping services usability. Moreover, participants were self-assessed in digital skills using the Digital Natives Assessment Scale. Results reveal differences among services in task accuracy indicating that not only the web-mapping service but also the nature of tasks guide participants’ performance. Correlations between spatial ability, digital skills, system usability, familiarity, and performance using web mapping services tend to be low and not significant leading to the assumption that success when interacting with a web mapping service is underlined by other factors as well.
