September 29 Coffee Hour with Guido Cervone: Citizen Science During Nuclear Emergency: Analysis of The Fukushima-Dahichi Nuclear Accident
The 2011 Fukushima-Daiichi nuclear accident resulted in a series of controlled and accidental releases of radioactive Cesium in the environment. The citizen science Safecast project was started immediately after the accident to map radiation using off the shelf instruments, and generated over 60 million observations since April 2011. A robust methodology is presented to calibrate contributed Safecast radiation measurements acquired between 2011 and 2016 in the Fukushima prefecture of Japan. The Safecast data are calibrated using official observations acquired by the U.S. Department of Energy at the time of the 2011 Fukushima Daiichi power plant nuclear accident.

Applying Critical Race And Memory Studies To University Place Naming Controversies: Toward A Responsible Landscape Policy
By Jordan Brasher, Derek H. Alderman, Joshua Inwood
Forthcoming in Papers In Applied Geography
Access http://www.tandfonline.com/toc/rpag20/current
A number of U.S. universities are embroiled in debates over the long-time commemoration and valorization of white supremacy through the campus landscape. Recognizing place naming as a legitimate political arena, activists have called for—and in some instances succeeded—in removing from university buildings the names of historical figures shrouded in racial controversy. However, for the broader public and even sympathetic higher education officials, there is a lack of understanding about why these demands are important and even less recognition about the violence that racially insensitive place naming inflicts on the belonging of marginalized groups. Instead, the renaming of campus landscapes is understood as merely an act of political correctness and thus campus authorities have offered uneven and incomplete solutions in the name of progressive reform. Applying recent innovations in race and memory studies, specifically the ideas of “wounded” places and “memory-work,” we situate ongoing university place naming controversies in a critical context. Specifically, we build upon the recent work of law scholar Stephen Clowney and discuss the opportunities and challenges of developing a policy of landscape fairness that recognizes the power of place to transmit ideas about racial power across generations and the right of critics to challenge dominant historical narratives.

Analysis of errors introduced by geographic coordinate systems on
weather numeric prediction modeling
By Yanni Cao, Guido Cervone, Zachary Barkley, Thomas Lauvaux, Aijun Deng, and Alan Taylor
In Geosci. Model Dev., 10, 3425–3440, 2017
Access https://doi.org/10.5194/gmd-10-3425-2017
Most atmospheric models, including the Weather Research and Forecasting (WRF) model, use a spherical geographic coordinate system to internally represent input data and perform computations. However, most geographic information system (GIS) input data used by the models are based on a spheroid datum because it better represents the actual geometry of the earth. WRF and other atmospheric models use these GIS input layers as if they were in a spherical coordinate system without accounting for the difference in datum. When GIS layers are not properly reprojected, latitudinal errors of up to 21 km in the midlatitudes are introduced. Recent studies have suggested that for very high-resolution applications, the difference in datum in the GIS input data (e.g., terrain land use, orography) should be taken into account. However, the magnitude of errors introduced by the difference in coordinate systems remains unclear. This research quantifies the effect of using a spherical vs. a spheroid datum for the input GIS layers used by WRF to study greenhouse gas transport and dispersion in northeast Pennsylvania.

Developing and Evaluating VR Field Trips

Access https://doi.org/10.1007/978-3-319-63946-8_22
We present our work on creating and assessing virtual field trip experiences using different VR and AR setups. In comparative studies, we address the question of how different settings and technologies compare regarding their ability to convey different kinds of spatial information and to foster spatial learning. We focus on a case study on an informal settlement in Rio, Brazil, in which we used an informal assessment to help inform and improve the design of different VR site experiences.

Immersive technologies have the potential to significantly improve and disruptively change the future of education and research. The representational opportunities and characteristics of immersive technologies are so unique that only the recent development in mass access fostered by heavy industry investments will allow for a large-scale assessment of the prospects. To further our understanding, this paper describes a project that aims at creating a comprehensive suite of immersive applications for archeological sites, including 360∘ immersive tours, skywalks, and self-guided explorations for education, and immersive workbenches for researchers.

Coffee Hour with Don McCandless | EcoChallenge | Geospatial advisory board



The Sustainability Institute at Penn State is piloting a new program called EcoChallenge to choose actions to reduce your impact. You pick your own challenge and set a goal that stretches your comfort zone and makes a difference for you, your community, and the planet. Challenges encompass a variety of eco-issues such as waste, food, health, transportation, energy, water, and nature, and range in difficulty. For example, one challenge could be using a reusable water bottle each day, while another challenge could be carrying your trash that you accumulate throughout the duration of the challenge.

September 22 Coffee Hour with Don McCandless: Research to Start-Up: Initial steps to technology commercialization for Penn Staters
The thought of translating fundamental research into a commercial product can appear mysterious and daunting to many in the research and academic community. However, there is a process, with multiple pathways, that can be followed to increase the chances of success. These paths are lumpy, not linear. But by creating and investigating “Business Models” (not a “Business Plan”), researchers can get a better idea on whether there is actually a commercial need for their proposed product/service. This process is currently being implemented at the national level thru I-Corps programming at NSF and NIH, as well as by the 68 teams in the past five years in our TechCelerator@StateCollege Entrepreneurial boot camps. Today’s talk will outline several ways to get started, including an overview of licensing, funding options, prototyping, team formation, and customer discovery techniques.

GEOGRAPH SU17: From the Department Head
(Your name here): Building community, supporting international travel, and celebrating excellence
A few times during the year, our college development folks email me about upcoming visits with alumni, and they ask me what our department funding priorities are. They might also ask what specific opportunities exist for someone with a special focus on x-y-z. So, as head, I need to think about our development priorities from two different points of view; first, what will strengthen and position the department overall for success, and second, what unique projects will appeal most to particular donors. I currently have four things on my general department funding wish list:

Penn State Online Geospatial Education advisory board meets
On Monday, August 28, the advisory board for the Penn State Online Geospatial Education program held its annual meeting. Each year, the board evaluates the MGIS degree and GIS, GEOINT, and Remote Sensing certificate programs. Members provide advice and insight on how we can continually refine our classes and programs to anticipate the needs of geospatial professionals and society. Members of the Advisory Board include senior leaders from Esri, CARTO, the National Geospatial-Intelligence Agency, eMap International, 18F, and Azavea, as well as from academic units within and outside of Penn State. Several board members are alumni of the Department of Geography and our online programs, ensuring that we have the voices of our students as well as their potential employers in mind.

At the 2017 meeting, board members reviewed course content with faculty and made suggestions on how to build upon the program’s strengths. Engagement with the board enhances our ability to respond to continuing changes in the geospatial professional landscape. In the year ahead we will be redesigning our core GIS Certificate courses based in part on Advisory Board recommendations.


SensePlace3: a geovisual framework to analyze place–time–attribute information in social media
By Scott Pezanowski, Alan M MacEachren, Alexander Savelyev & Anthony C Robinson
In Cartography and Geographic Information Science
Access http://dx.doi.org/10.1080/15230406.2017.1370391
SensePlace3 (SP3) is a geovisual analytics framework and web application that supports overview + detail analysis of social media, focusing on extracting meaningful information from the Twitterverse. SP3 leverages social media related to crisis events. It differs from most existing systems by enabling an analyst to obtain place-relevant information from tweets that have implicit as well as explicit geography. Specifically, SP3 includes not just the ability to utilize the explicit geography of geolocated tweets but also analyze implicit geography by recognizing and geolocating references in both tweet text, which indicates locations tweeted about, and in Twitter profiles, which indicates locations affiliated with users. Key features of SP3 reported here include flexible search and filtering capabilities to support information foraging; an ingest, processing, and indexing pipeline that produces near real-time access for big streaming data; and a novel strategy for implementing a web-based multi-view visual interface with dynamic linking of entities across views. The SP3 system architecture was designed to support crisis management applications, but its design flexibility makes it easily adaptable to other domains. We also report on a user study that provided input to SP3 interface design and suggests next steps for effective spatiotemporal analytics using social media sources.

GeoCorpora: building a corpus to test and train microblog geoparsers
By Jan Oliver Wallgrün, Morteza Karimzadeh, Alan M. MacEachren & Scott Pezanowski
In International Journal of Geographical Information Science
Access http://dx.doi.org/10.1080/13658816.2017.1368523
In this article, we present the GeoCorpora corpus building framework and software tools as well as a geo-annotated Twitter corpus built with these tools to foster research and development in the areas of microblog/Twitter geoparsing and geographic information retrieval. The developed framework employs crowdsourcing and geovisual analytics to support the construction of large corpora of text in which the mentioned location entities are identified and geolocated to toponyms in existing geographical gazetteers. We describe how the approach has been applied to build a corpus of geo-annotated tweets that will be made freely available to the research community alongside this article to support the evaluation, comparison and training of geoparsers. Additionally, we report lessons learned related to corpus construction for geoparsing as well as insights about the notions of place and natural spatial language that we derive from application of the framework to building this corpus.

Flying down to Rio
Students use digital technology to explore design solutions for Brazilian favela
As the world’s population grows, so does the problem of affordable housing. In some rapidly growing urban areas, particularly in developing countries, the only recourse is to build your own.

The informal settlements that pop up on the edges of many modern cities are often derided as problem areas or slums, ramshackle neighborhoods beset with sanitation issues and crime. To Jose Duarte, however, they are “not a problem to be solved, but a solution that has some problems.”

A regional assessment of white-tailed deer effects on plant invasion
By KM Averill, DA Mortensen, EAH Smithwick, S Kalisz, and others
In Annals of Botany Plants, 2017
Access: doi.org/10.1093/aobpla/plx047
Herbivores can profoundly influence plant species assembly, including plant invasion, and resulting community composition. Population increases of native herbivores, e.g., white-tailed deer (Odocoileus virginianus), combined with burgeoning plant invasions raise concerns for native plant diversity and forest regeneration. While individual researchers typically test for the impact of deer on plant invasion at a few sites, the overarching influence of deer on plant invasion across regional scales is unclear. We tested the effects of deer on the abundance and diversity of introduced and native herbaceous and woody plants across 23 white-tailed deer research sites distributed across the east central and northeastern United States and representing a wide range of deer densities and invasive plant abundance and identity.

September 8 Coffee Hour with Erica Smithwick
Transformative Learning Spaces for an Uncertain World
Resilience is about complexity, change, and coping with uncertainty. It depends on a deep understanding of intertwined socio-ecological systems. However, uncertainty and complexity in both socio-ecological systems increasingly hinders decision-making. New knowledges and ontologies are needed to transform society for a mature Anthropocene. Using case studies from Ghana, South Africa, and the Menominee Nation (Wisconsin), Erica Smithwick will explore how biosphere stewardship can be enhanced through transformative research and education approaches that embrace interdisciplinary and cross-cultural ways of knowing.
