Presentation by David Maidment

NCGIA is pleased to welcome David Maidment for a talk entitled:

“From magnifying glass to microscope: the new National Water Model”

Abstract:

In August 2016 the National Weather Service launched the new National Water Model, which continually forecasts the flow in 2.7 million stream reaches covering 3.2 million miles of rivers and streams of the continental United States.  From atmosphere to the oceans, from coast to coast, water is now forecast just like weather – at local scale, and in near real-time.  The seminar will describe how the National Water Model came about, what it does, and what it may mean for the future of water resources science and management in the United States.

David R. Maidment is the Hussein M. Alharthy Centennial Chair in Civil Engineering at the University of Texas at Austin, where he has been on the faculty since 1981.  He is a surface water hydrologist, and was elected to the National Academy of Engineering in 2016 for development of geographic information systems applied to hydrologic processes.

Evaluating and Alleviating Cognitive Map Decay for Older Adult Navigators through the use of Virtual Reality Simulation

Abstract. The aging process is associated with changes to various tasks of daily life for older adults, e.g. driving and walking. This is particularly challenging in rural areas where public transportation is often non-existent. The current research explored how age affects navigation ability through use of virtual reality simulations. Particularly, these research studies focus on the decay of cognitive maps (mental representations of space) for older adult navigators over time. In each study, participants were required to learn and sketch cognitive maps of various virtual environments at several time intervals (in-lab and after 1-day, 1-week, and 2-weeks). Results consistently show that older adult performance was lower than the younger adult group and also revealed declines of cognitive map accuracy over the time delay periods. Results also demonstrate the efficacy of immersive virtual reality as an effective research tool. Based on these findings, compensatory augmentations (navigational aids) are currently being developed and tested. This research provides evidence for cognitive map decay, implications of potential solutions, and enriches the understanding of navigation and age-related concerns.

Spatial Preposition Use in Indoor Scene Descriptions

Abstract. In order to provide accurate automated scene description and navigation directions for indoor space, human beings need intelligent systems to provide an effective cognitive model. Information provided by the structure and use of spatial prepositions is critical to the development of accurate and effective cognitive models. The use and choice of spatial prepositions in natural language is extremely varied, presenting difficulties for natural language systems attempting to provide descriptions of indoor scenes and wayfinding directions. The goal of the present study is to better understand how English language speakers use spatial prepositions to communicate spatial relationships within virtual environment (VE) indoor scenes. This talk will present findings from a series of experiments that investigate spatial preposition use and the influence of scale, topology, orientation and distance within indoor scene.

Priority Amphibian and Reptile Conservation Areas (PARCAs): Applying quantitative approaches and expert opinion to identify conservation areas and evaluate vulnerability

 

Abstract. The PARCA project is a national initiative to map important amphibian and reptile habitats based on knowledge of species’ distributions and habitat associations. We applied PARCA guidelines with species distribution modeling via the Maximum Entropy algorithm to model habitat suitability for northeastern herpetofauna of conservation significance. Our modeled PARCAs combined habitat suitability models based on known species occurrences and important abiotic variables with species richness and landscape integrity estimates. We evaluated our models by comparing predicted with observed data, identified gaps in species occurrence and richness datasets affecting model outcomes, consulted with state herpetologists to understand how our spatial application of the PARCA criteria captured quality habitat for modeled species, and evaluated representation of PARCAs in the network of current conservation lands. Our efforts can inform conservation of priority landscapes for northeastern herpetofauna, including assessment of the long-term vulnerability and climate resiliency of these habitats.

Seeking Space and Place in the Holocaust

Abstract. The Holocaust has become a new focus of spatial historical research, both theoretical and empirical. The wealth of bureaucratic records and plans makes it relatively easy to map Nazi actions, the establishment and demise of camps and ghettos, and Nazi spatial visions for the Reich. Although interviews with Holocaust survivors contain many kinds of spatial information, much of it is poorly suited to GIS and other modes of conventional geographical analysis and representation. This presentation will explain the issues of bridging the gap between perpetrator and victim histories in the Holocaust, and describe the modes of textual analysis that may enable spatial interpretation of victims’ experiences.

NCGIA- Maine has strong representation at COSIT

Several faculty and students from NCGIA- Maine presented at COSIT  held this year in Sante Fe, New Mexico.

Max Egenhofer, current Ph.D. student Joshua Lewis, M.S. student Shirly Stephen, and former student Mark Plummer were authors on the paper titled “Swiss Canton Regions: A Model for Complex Objects in Geographic Partitions.” This paper explores the ability to construct queries that go beyond the simple topological queries to more complex representation where separations, holes, and self-adjacency matter.

Upward Bound Math-Science student Jordan Barrett, now attending Syracuse University for Mathematics and Physics and Max Egenhofer collaborated the  pape “From Metric to Topology: Determining Relation in Discrete Spaces.” This paper presented a set of metrics that can uniquely identify simple topological relations between pixelized objects where the boundary is considered to be the outer set of pixels.

Ph.D. student Christopher Dorr, Reinhard Moratz, and Longin Jan Latecki from Temple University collaborated on the paper “Shape Similarity Based on the Qualitative Spatial Reasoning Calculus eOPRA.” The paper investigated the use of qualitative spatial representations (QSR) about relative direction and distance for shape representation.

Professor Torsten Hahmman and Lynn Usery of the U.S. Geological Survey collaborated on a paper is entitled “What is in a Contour Map? A Region-based Logical Formalization of Contour Semantics.” This paper analyses and formalizes contour semantics in a first-order logic ontology that forms the basis for enabling computational common sense reasoning about contour information.

PhD candidate Stacy Doore presented her research on “Spatial Preposition Specification for Improved Scene Descriptions” at the Doctoral Colloquium session. Her research investigates usage and preferences for spatial prepositions in describing different indoor scene settings.
