This shift seeks to move away from extractive research practices by fostering collaborations built on reciprocity and respect - particularly with Indigenous and marginalized groups. At the core of this approach is co-produced knowledge, wherein communities actively shape research priorities, methodologies, and interpretations. Rather than imposing external frameworks, these collaborations recognize the value of local and Indigenous knowledge systems in informing research and driving meaningful outcomes. In this paper, we review contemporary CBR literature in geography and GIScience and present a case study on environmental health concerns related to mining legacies in the U.S. This research, led by GIScience and geospatial experts in collaboration with a Tribal community, illustrates opportunities to advance CBR theory and practice within these fields. As CBR becomes increasingly integrated into GIScience projects, we critically examine the positionality of GIScience researchers in this transition, the challenges they face, and the lessons learned. The paper closes with a discussion of best practices for CBR. While all research involves some degree of extractivism, we explore how CBR can help ensure that communities derive direct and tangible benefits from participation in GIScience and geography research.</p>","PeriodicalId":47562,"journal":{"name":"Cartography and Geographic Information Science","volume":"53 1","pages":"113-128"},"PeriodicalIF":2.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12782218/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145953340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

COVID-19 case and death data are essential to understanding the pandemic and serve as key inputs for prediction models that inform policy-decisions; consistent information across datasets is critical to ensuring coherent findings. We implement an exploratory data analytic approach to characterize, synthesize, and visualize spatial-temporal dimensions of uncertainty across commonly used datasets for case and death metrics (Johns Hopkins University, the New York Times, USAFacts, and 1Point3Acres). We scrutinize data consistency to assess where and when disagreements occur, potentially indicating underlying uncertainty. We observe differences in cumulative case and death rates to highlight discrepancies and identify spatial patterns. Data are assessed using pairwise agreement (Cohen's kappa) and agreement across all datasets (Fleiss' kappa) to summarize changes over time. Findings suggest highest agreements between CDC, JHU, and NYT datasets. We find nine discrete type-components of information uncertainty for COVID-19 datasets reflecting various complex processes. Understanding processes and indicators of uncertainty in COVID-19 data reporting is especially relevant to public health professionals and policymakers to accurately understand and communicate information about the pandemic.</p>","PeriodicalId":47562,"journal":{"name":"Cartography and Geographic Information Science","volume":"1 1","pages":"200-221"},"PeriodicalIF":2.6,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11196018/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44113959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although multivariate maps have attracted research for decades, only several studies have compared the effectiveness of maps that use extrinsic and intrinsic encoding styles, and even fewer have tried to incorporate other map-related factors that could significantly affect the user’s performance and clarify the relationship between the selected encoding style’s efficiency and the user’s cognitive processes. In this paper, we report on an empirical replication study focused on the performance differences of experienced map users solving a task using a map and the possible effect of their cognitive styles on the efficiency of bivariate map encoding styles and the map task type. For the experiment, we recruited 77 spatial planning and geography university students in China considered as experienced map users. The study indicated that extrinsic visualizations outperformed intrinsic visualizations in the main observed variables of correctness and response time but not always significantly. A detailed analysis of the tasks, which involved the use of either one variable or two variables concurrently, confirmed our hypothesis.KEYWORDS: Bivariate mapextrinsicintrinsiccognitive styleresponse timeaccuracy AcknowledgmentsThe study was supported by the Czech Science Foundation (GC19-09265J: The Influence of Socio-Cultural Factors and Writing Systems on the Perception and Cognition of Complex Visual Stimuli.

{"title":"Keeping walls straight: data model and training set size matter for deep learning in building generalization","authors":"Cheng Fu, Zhiyong Zhou, Yu Feng, Robert Weibel","doi":"10.1080/15230406.2023.2264757","DOIUrl":"https://doi.org/10.1080/15230406.2023.2264757","url":null,"abstract":"ABSTRACTDeep learning-backed models have shown their potential of conducting map generalization tasks. However, pioneering studies for raster-based building generalization encountered a common “wabbly-wall effect” that makes the predicted building shapes unrealistic. This effect was identified as a critical challenge in the existing studies. This work proposes a layered data representation model that separately stores a building for generalization and its context buildings in different channels. Incorporating adjustments to training sample generation and prediction tasks, we show how even without using more complex deep learning architectures, the widely used Residual U-Net can already produce straight walls for the generalized buildings and maintains rectangularity and parallelism of the buildings very well for building simplification and aggregation in the scale transition from 1:5,000 to 1:10,000 and 1:5,000 to 1:15,000, respectively. Experiments with visual evaluation and quantitative indicators such as Intersection over Union (IoU), fractality, and roughness index show that using a larger input tensor size is an easy but effective solution to improve prediction. Balancing samples with data augmentation and introducing an attention mechanism to increase network learning capacity can help in certain experiment settings but have obvious tradeoffs. In addition, we find that the defects observed in previous studies may be due to a lack of enough training samples. We thus conclude that the wabbly-wall challenge can be solved, paving the way for further studies of applying raster-based deep learning models on map generalization.POLICY HIGHLIGHTS Demonstrates the effectiveness of the proposed data structure with multiple evaluation indicatorsIdentifies a “wabbly-wall effect” a challenge in deep-learning backed image based map generalizationProposes a layered data structure that separates a target building and its surrounding buildings to ease the learning task in training deep learning models for raster-based map generalization.KEYWORDS: Map generalizationdeep learningrasterbuilding simplificationU-Net AcknowledgmentsThe authors also appreciate the comments of four anonymous reviewers which helped improve the paper.Disclosure statementNo potential conflict of interest was reported by the author(s).Data availability statementThe raw maps that support the findings are available by request to Dr Yu Feng (y.feng@tum.de).
