Summary: Over the past decade, the number of refugees and internally displaced people has doubled, leading to the construction of more refugee camps with diverse structures. However, there is currently no standardized inventory for these camp structures. In this study, a global database of settlement structures from 285 camps was created using satellite imagery and visual image interpretation. The findings highlight the importance of considering morphological differences in image analyses and provide a foundation for future humanitarian applications.

Summary: Variable precision rough set (VPRS) has been widely studied as an essential way of knowledge representation and acquisition in uncertainty theory. This paper investigates the corresponding CVPRS model based on a covering-based rough set model, and systematically studies its algebraic structures and properties. An attribute reduction approach is proposed for a covering-based decision information system using the CVPRS model, and the performances of different boundary operators and related indices in these reduction methods are compared. Necessity rules and possibility rules extraction methods corresponding to decision classes are established, and their validity and security are theoretically verified.

Summary: The paper presents and evaluates an approach based on Rough Set Theory to analyze Information Disorder phenomena. Rough Set Theory concepts and constructs are used to model and reason on social media user groups and sets of information. Information theoretic measures are used to evaluate Complexity and Milestone concepts in Information Disorder. The adoption of Rough Set Theory constructs and operators in this new field allows for modeling and reasoning on key elements of Information Disorder and interpreting its effects.

Summary: In Yemen, community-based surveillance was effective in detecting suspected outbreaks in IDP camps. However, in the early stages of the COVID-19 pandemic, the system failed to produce expected results in general communities in urban settings where little was known about the disease. Feasibility and acceptability studies should be conducted before expanding CBS in urban communities, while also expanding the project in IDP camps with dedicated reporting sites for COVID-19 and other outbreaks.

Summary: This paper proposes a new distributed lattice Kalman filter (DLKF) to deal with the high-dynamic and communication coupling in multiple micro-target tracking and positioning. The DLKF uses Cranley-Patterson shift and Korobov lattice rule for prediction, and weighted average consistency for update fusion. Simulation results show that DLKF achieves estimation accuracy with significantly fewer sampling points compared to other quasi-Monte Carlo (QMC) filters, and has significantly lower computational complexity for application to multiple micro-targets.

Summary: This paper proposes a Z-number-valued rule-based decision tree (ZRDT) and provides the learning algorithm. Compared with other classical decision trees, ZRDT performs better in terms of classification accuracy and decision tree size. ZRDT uses information gain to select features in each rule instead of fuzzy confidence, and generates a second fuzzy number with negative samples to improve the model's fit to the training data. Based on statistical tests, ZRDT achieves the highest classification performance with the smallest size for the produced decision tree.

Summary: This paper discusses the importance of granular representations of crisp and fuzzy sets in rule induction algorithms based on rough set theory. It demonstrates that the OWA-based fuzzy rough set model, which has been successfully applied in various machine learning tasks, allows for a granular representation. The practical implications of this result for rule induction from fuzzy rough approximations are highlighted.

Summary: With the advancement of positioning technology, the application and demand for location information have gained attention from various industries. In this paper, a novel 3D low-cost, high-precision target perception algorithm is introduced using an RFID mobile reader and double tags.

Summary: The alpine infrastructure of trails and huts is crucial for summer tourism, but is prone to damage from mass movements caused by extreme rainfall events. This study utilized susceptibility mapping techniques to assess the mass movement susceptibility of alpine hut and trail infrastructure in Austria. Two statistical methods, logistic regression and informative value, were employed and compared, with both methods showing high prediction rates. Field validation demonstrated the reliability of the informative value method. Alpine associations recognize the potential of susceptibility mapping for strategic management of alpine infrastructure.

Summary: In this study, two-dimensional deformation estimates derived from Persistent Scatterer Interferometric (PSI) analysis of Synthetic Aperture Radar (SAR) data were examined for their improved characterization of spatially and temporally varying deformation processes of Earth's surface. By analyzing Sentinel-1 SAR image data from 2015 to 2018, the study obtained 2D vertical and horizontal surface deformation velocities, which showed good agreement with independent GPS measurements.

Summary: This article explores the technology landscape for managing big Earth observation data and the importance and challenges of local EO data cubes. By analyzing examples of global and local EO data cubes, it is found that local EO data cubes can benefit various stakeholders but require technical developments such as establishing global and cloud-native EO data streaming mechanisms. The article argues that blurring the dichotomy between global and local aligns with the vision of the Digital Earth.

Summary: The current climate change in the Arctic has unprecedented impacts on the environment and landscape. In Arctic Sweden, aeolian sand dunes are affected by climate changes, and their type, location, and orientation can be used to understand past wind patterns and landscape destabilization. Geographic object-based image analysis is a suitable method to map these dunes. The study reveals that glaciofluvial and fluvial disturbances played a significant role in the formation of dune systems in Arctic Sweden.

Summary: This study proposes an evaluation method using C-band Sentinel-1 synthetic aperture radar (SAR) data to provide evidence of flood characteristic changes after the restoration of a floodplain. The evaluation framework replicates previous change detection research approaches and analyses the effects of Natural Flood Management (NFM) measures on flood risk mitigation. The study verifies the change detection methodology using flood records from drone footage and achieves an overall accuracy of 75% using the Change Detection and Thresholding (CDAT) technique. The use of SAR data maps the actual flood extent and evaluates the positive and negative outcomes of post-restoration floods.

Summary: More than half of the world's population lives in urban areas, with over 1 billion people lacking basic services and infrastructure. Spatially targeted, data-driven policies are crucial for sustainable urban planning to improve these situations and increase resilience. Earth observation can support the achievement of the Sustainable Development Goals, particularly SDG 11. The integration of heterogeneous datasets for humanitarian response requires adequate data assimilation strategies and a good understanding of data quality.
