On Tuesday, January 30, 2018 The UCSB brown-bag forum on spatial thinking presents Hydrologic Dynamics of the Greenland Ice Sheet Vena W. Chu Department of Geography University of California, Santa Barbara 12:00 p.m. Tuesday, January 30, 2018 | 3512 Phelps Hall (map) Flyer Abstract: The current need for forecasting Greenland Ice Sheet contributions to global sea level rise is complicated by the lack of understanding of ice sheet hydrology. The proportion of meltwater contributing to sea level rise, as well as the pathways transporting meltwater from snow to sea are not well understood. This presentation examines components of the Greenland hydrologic system using geospatial technologies and field measurements to understand the spatial and temporal dynamics of meltwater runoff. I will highlight recent work on supraglacial rivers and moulins that explores how well current models represent when, where, and how much water leaves the ice sheet. Bio: Vena W.

Spatial Tech Lunch: Erin Wetherley

Nov 29, 2017 • Categories: Event | Spatial Tech Lunch

On Tuesday, December 5, from 12:00–1:00 pm please join us for the next Spatial Technology Lunch in the Center for Spatial Studies (Phelps Hall 3512). This semi-regular series, hosted by spatial@ucsb, aims to promote discussion and interaction within the university’s spatial technology community. Please RSVP to Crystal Bae (cbae@spatial.ucsb.edu) by Sunday, December 3. Pizza and drinks will be provided. Evaluating vegetation type effects on land surface temperature at the city scale Erin Wetherley Abstract: The growing concentration of the global human population into cities has coincided with the rise of increasingly rich remote sensing data. Near-future hyperspectral/thermal satellites could revolutionize our understanding of urban environments by allowing us to discriminate urban materials and examine their thermal properties. With this wealth of information, we will be able to disentangle the links between land cover, management, and climate at the city scale for the very first time, with significant consequences for improved modeling of urban climate, energy, and water use, as well as targeted urban planning and public health initiatives. I will present new results in which we sampled the material and thermal heterogeneity of the Los Angeles, CA, metropolitan area (4,283 km2) to quantify, analyze, and model surface drivers of urban heat. We used airborne hyperspectral imagery (AVIRIS: 36 m resolution, 224 bands, 0.35 – 2.5 μm) to produce robust estimates of fine-scale (sub-pixel) urban patches, defined as mixtures of key urban surface classes. We then used airborne MASTER thermal imagery to quantify and model surface temperature changes as patch mixtures transitioned from low to high proportions of vegetation. Significant differences were observed between tree, turfgrass, senesced vegetation, and impervious mixtures. Finally, we used our modeled and measured temperatures to observe and quantify additional urban microclimate drivers beyond urban patch type, including income levels, building fraction, and irrigation.

ThinkSpatial: Alexander Franks

On Tuesday, November 21, 2017 The UCSB brown-bag forum on spatial thinking presents “From Pixels to Points: Using Tracking Data to Measure Performance in Professional Sports” Alexander Franks Department of Statistics University of California, Santa Barbara 12:00 p.m. Tuesday, November 21, 2017 | 3512 Phelps Hall (map) Flyer Abstract: New optical tracking technologies are increasingly used to gather high resolution spatial and time series data in professional sports. In the National Basketball Association (NBA), the technology is used to record the positions of the players and the ball at 25 frames/second, yielding hundreds of millions of observations per season. In this talk, I will describe a series of spatio-temporal models for quantifying the game of basketball. By blending Bayesian hierarchical models with geography inspired mapping tools, we will shed light on previously unidentified aspects of play. Specifically, we develop models to describe spatial variation of defensive ability, the value of decision-making and propose a model for clustering player trajectories. Importantly, efficient inference requires models that pool information both between players and across space. Although we apply these methods to professional basketball data, we emphasize the applicability of our methods to a wide range of domains. Bio: Alex Franks is an Assistant Professor in the Department of Statistics and Applied Probability. His research interests include covariance estimation, multivariate analysis and high dimensional data, errors-in-variables models, missing data, and spatio-temporal methods. His primary focus is on applications in computational and systems biology. He is also a member of XY Research (xyresearch.com), a group that conducts research in sports statistics with a focus on playertracking data. — The objectives of the ThinkSpatial brown-bag presentations 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.

Nov 16, 2017 • Categories: Event

On Thursday, November 16 at 12:00pm, please join us for a talk by Pascal Hitzler in the Center for Spatial Studies (Phelps Hall 3512). “A Brief Introduction to Semantic Web – and a Contribution to Explainable Artificial Intelligence” Pascal Hitzler Department of Computer Science and Engineering Wright State University 12:00pm Thursday, November 16, 2017 | 3512 Phelps Hall (map) Abstract: Semantic Web as a field of research and applications is concerned with methods and tools for data sharing, discovery, integration, and reuse, both on and off the World Wide Web. In the form of knowledge graphs and their underlying schemas, Semantic Web technologies are currently entering industrial mainstream. At the same time, the ever increasing prevalence of publicly available structured data on the Semantic Web enables new applications in a variety of domains, and as part of this presentation, we provide a conceptual approach that leverages such data in order to explain the input-output behavior of trained artificial neural networks. We apply existing Semantic Web technologies in order to provide an experimental proof of concept. Bio: Pascal Hitzler is endowed NCR Distinguished Professor and Director of Data Science at the Department of Computer Science and Engineering at Wright State University in Dayton, Ohio, U.S.A. His research record lists over 350 publications in such diverse areas as semantic web, neural-symbolic integration, knowledge representation and reasoning, machine learning, denotational semantics, and set-theoretic topology. He is Editor-in-chief of the Semantic Web journal by IOS Press, which is the leading journal in the field, and of the IOS Press book series Studies on the Semantic Web. He is co-author of the W3C Recommendation OWL 2 Primer, and of the book Foundations of Semantic Web Technologies by CRC Press, 2010 which was named as one out of seven Outstanding Academic Titles 2010 in Information and Computer Science by the American Library Association’s Choice Magazine, and has translations into German and Chinese. He is on the editorial board of several journals and book series and is a founding steering committee member of the Neural-Symbolic Learning and Reasoning (NeSy) workshop series, and of the Association for Ontology Design and Patterns (ODPA).
