Abstract: Adapting to climate change and variability, and their associated impacts, requires integrating scientific information into complex decision-making processes. Recognizing this challenge, there have been widespread calls for information providers and scientists to work closely with decision makers to ensure they produce datasets and tools that meet real-world needs. Despite the emphasis on integrating user needs into the design of resources, tool developers often do not understand the range of ways their tools are actually incorporated into the decisions of potential users nor the reasons why someone might opt not to use a seemingly-relevant tool. Therefore, there is a need to better understand the specific social and institutional factors that influence why users use (or do not use) particular resources as well as the strategies that tool developers use to engage with users. Using the Upper Colorado River Drought Early Warning System as a case study, this study explored both the process of tool development and the process by which tool users find relevant information for drought decision making. Understanding these two groups’ experiences suggests ways to more effectively design and implement decision support tools in the future.

Geospatial information informs conservation and community forest management in the Democratic Republic of the Congo

Dr. Janet Nackoney

United States Agency for International Development (USAID)
& Department of Geographical Sciences at the University of Maryland

11:00 am (PT), Thursday, January 13, 2022 (online)

See presentation slides, below.

Abstract: Geospatial tools and data are increasingly applied to help conservation managers develop more effective strategies for the protection and long-term conservation of species and the habitats they rely on. These data can help inform the quality or condition of habitats, locate areas most important for conservation prioritization, and systematically monitor areas that are vulnerable to land cover and land use change. Recent advances in satellite-based forest monitoring have significantly increased awareness about the geographic extent of the world’s tropical forests; decision-makers now have much greater access to valuable data and tools to detect forest loss and change over time. Here, geospatial data and tools were utilized to assist habitat monitoring and conservation prioritization for the bonobo (Pan paniscus), an endangered great ape that is endemic to the Democratic Republic of the Congo (DRC). Community mapping, geospatial analysis and modeling have helped identify conservation priorities for bonobos and other terrestrial species, monitor forest loss and habitat destruction, and promote community-based forest management with local communities.

Janet NackoneyBio: Dr. Janet Nackoney is jointly affiliated with the United States Agency for International Development (USAID) Land and Resource Governance Division and the University of Maryland’s Department of Geographical Sciences. Janet is a trained geographer who uses geospatial data and technology to monitor tropical forests, conserve wildlife, manage land more sustainably, and promote food security. She is passionate about exploring the intersections and tensions between human and environment systems and helping to promote more inclusive and equitable access to land and property in the developing world. She currently serves on the Board of Directors for the Society for Conservation GIS (SCGIS) and for Congo Education Partners, which assists a small rural college in northern Democratic Republic of the Congo (DRC).

Time-lapse video of participatory mapping exercise pictured above

Abstract: Over the past two years, the National Science Foundation funded the initiation of a regional research network on sustainable development and community resilience in the Lower Great Lakes. OUTSTEPS.org utilizes a novel approach to engage scientists, stakeholders, and Indigenous Rightsholders to look at natural and social processes from a new perspective when addressing regional climate change and land use changes in coastal watersheds. The approach creates interdisciplinary teams to investigate spatial and temporal patterns around conservation and development challenges under climate change. Team individuals identify their expertise and interest in the 17 UN Sustainable Development Goals (SDGs) and the seven PEOPLES Resilience Framework Dimensions. This approach allows participants to converge as matching research partners creating interconnected teams working collaboratively on innovative research questions hypotheses at the regional scale. Several projects at the local scale feature a focus on assessing more detailed process patterns in environmental management and conservation. Among them are process-based modeling of runoff and soil redistribution, bioacoustics and bat habitat assessment, and a discussion to integrate social-cultural aspects in climate change impact and adaption assessment at the local scales.

Bio: Chris S. Renschler is a Professor in Geography and Director of the Geographic Information and Analysis Lab (GIAL) at the University at Buffalo (SUNY), Buffalo, NY. He is also the Director of the Landscape-based Environmental System Analysis & Modeling (LESAM) Lab. Renschler is recognized internationally as an expert and scholar in soil and water conservation, integrated watershed, natural resources, and hazards management. His research, teaching, and outreach activities include the development, validation, and application of integrated hydrology and sediment modeling tools developed collaboratively by scientists, engineers, and practitioners to support effective decision- and policy-making under global climate and land use/land cover change.

The objectives of the ThinkSpatial Forum are to exchange ideas about spatial perspectives in research and teaching, to broaden communication and cooperation across disciplines among faculty and graduate students, and to encourage the sharing of tools and concepts.

A Spatial Decision Support System and Open Knowledge Network for Fire-Risk Reduction in Santa Barbara County

John Gallo, Ph.D.

Conservation Biology Institute

11:00 am (PT), Thursday, December 2, 2021

View a PDF of the presentation’s slides.

Abstract. Extreme wildfire events are an increasing threat to both human and natural communities in the Western United States. Efforts to mitigate this threat are extremely complex and involve a bevy of jurisdictions and competing interests. Spatial Decision Support Systems (SDSS) can help these socio-political processes come to consensus on where people should do what treatments. Open Knowledge Networks (OKN), in addition, can help with the aspatial aspects of decision-making and action. Through this “Regional Priority Planning” project, funded by the California Coastal Conservancy and in part by the National Science Foundation, we pilot an SDSS and an OKN for Wildfire Risk Reduction in Santa Barbara County. The SDSS uses the Environmental Evaluation Modeling System (EEMS), a multicriteria combination software with a graphical user interface in DataBasin.org and eemsonline.org. SDSS development continues as part of the Regional Wildfire Mitigation Program funded by the National Wildlife Foundation. I will detail the SDSS and give a demonstration of its use. The OKN, which is in a more preliminary phase, will be described in terms of its underlying science, path and process.

What Are Links in Linked Open Data? A Characterization and Evaluation of Links between Knowledge Graphs on the Web

Armin Haller

Australian National University

3:00 p.m. (PT)

Thursday, April 8, 2021

The recorded video of this talk can be found here.

Slides can be found here.

 

Abstract. Linked Open Data promises to provide guiding principles to publish interlinked knowledge graphs on the Web in the form of findable, accessible, interoperable, and reusable datasets. I will argue that while as such, Linked Data may be viewed as a basis for instantiating the FAIR principles, there are still a number of open issues that cause significant data quality issues even when knowledge graphs are published as Linked Data. In this talk I will first define the boundaries of what constitutes a single coherent knowledge graph within Linked Data, i.e., present a principled notion of what a dataset is and what links within and between datasets are. I will also define different link types for data in Linked datasets and present the results of our empirical analysis of linkage among the datasets of the Linked Open Data cloud. Recent results from our analysis of Wikidata, which has not been part of the Linked Open Data Cloud, will also be presented.

Bio. Armin Haller is an Associate Professor of Business Information Systems at the Australian National University. His research interests include knowledge graph engineering, ontology engineering, linked data, the Internet-of-Things and the semantic Web in general. Haller has received funding from organisations including: the Department of Finance, to develop an ontology framework for government information and an open-source software that allows domain experts to maintain knowledge graphs called Schímatos; and from the Australian Research Council’s Linkage Program, for a project with Sydney Trains. He has published in the premier journals and conferences in his field, including Semantic Web Journal, Journal of Web Semantics, Applied Ontology, World Wide Web Conference and the International Semantic Web Conference. Haller has been an active contributor to several W3C working groups and chaired the Semantic Sensor Network Ontology working group. This work has resulted in an international standard for the description of sensors and actuators on the Internet-of-Things.

Abstract. Unsupervised text encoding models have recently fueled substantial progress in NLP. The key idea is to use neural networks to convert words in texts to vector space representations (embeddings) based on word positions in a sentence and their contexts, which are suitable for end-to-end training of downstream tasks. We see a strikingly similar situation in spatial analysis, which focuses on incorporating both absolute positions and spatial contexts of geographic objects such as POIs into models. A general-purpose representation model for space is valuable for a multitude of tasks. However, no such general model exists to date beyond simply applying discretization or feed-forward nets to coordinates, and little effort has been put into jointly modeling distributions with vastly different characteristics, which commonly emerges from GIS data. Meanwhile, Nobel Prize-winning Neuroscience research shows that grid cells in mammals provide a multi-scale periodic representation that functions as a metric for location encoding and is critical for recognizing places and for path-integration. Therefore, we propose a representation learning model called Space2Vec to encode the absolute positions and spatial relationships of places. We conduct experiments on two real-world geographic data for two different tasks: (1) predicting types of POIs given their positions and context, (2) image classification leveraging their geo-locations. Results show that because of its multi-scale representations, Space2Vec outperforms well-established ML approaches such as RBF kernels, multi-layer feed-forward nets, and tile embedding approaches for location modeling and image classification tasks. Detailed analysis shows that all baselines can at most well handle distribution at one scale but show poor performances in other scales. In contrast, Space2Vec ’s multi-scale representation can handle distributions at different scales.
