Scientific Solutions in Byte Size (Setempber 1 - October 31, 2017 issue)

It’s been a fruitful fall season for the scientific solutions team - we have been active in several conferences while making progress in our ongoing projects.

First, congratulations to Rajesh for being named Young Professional of the Year by the Science Gateways Community Institute (SGCI) in recognition of his work on multiple science gateways including the GABBs project most recently. A well-deserved award for Rajesh!

Presentations at Gateways 2017

Several from the team participated in the conference last week at U of Michigan. Rob presented our latest work on extending GABBs to work with field data collection via mobile apps (paper and slides). Rajesh demonstrated how a science project could utilize GABBs geospatial data management and workflow features (paper and slides). The team also had discussions with interested projects around its poster at the conference.

Abstracts to AGU accepted

All of our submitted abstracts have been accepted for presentation at the AGU Fall Meeting 2017 in New Orleans! Larry will give a talk on the MultiSpec online tool. Rajesh will present a poster on the MyGeoHub geospatial gateway. Our collaborating scientist Adnan in civil engineering will present a poster on helping hydrologic modellers prepare earth observation data using HydroGlobe, an application that we have developed on MyGeoHub. 

GABBs@SGCI Bootcamp, October 2017

Carol and Carolyn attended the weeklong bootcamp with GABBs as the project focus with a cohort of other Science Gateways professionals. Topics included many of the business related items that come with launching a successful product within the available opportunities in the current market. Topics included: defining the value proposition, understanding the current & growth audience, determining market fit, goal setting, budgeting, technology selection, outreach with your product, long term sustainable funding models, and developing meaningful metrics around these objectives. It was a great week - we came out with tools and a pitch deck, as well as new connections to people through networking at the bootcamp.

The GLASS project & Impacts World conference

The GLASS project (DP Big Idea) is taking off with lots of activities. GLASS is hosted as a supergroup and featured prominently on the homepage of MyGeoHub. The web site has been launched and is being continuously updated with new contents and tool releases. As the first major development milestone, Jungha integrated policy impacts modeling into the SIMPLE-G tool. The new functions supports research on the impacts of policy interventions in different geographic regions on food security. The release was in time for the GLASS team’s presentations at the Impacts World 2017 conference where Carol Song and other members of the GLASS team joined more than 450 participants from 68 countries in Potsdam, Germany to discuss challenges and solutions in climate-impacts research. Carol gave a presentation titled "An opensource geospatial cyberinfrastructure for interdisciplinary collaboration and broader engagement" (slides) on the scientific applications enabled by MyGeoHub and the geospatial building blocks software. The capabilities demonstrated through SIMPLE-G attracted quite a bit of attention, including requests to host additional tools, workflow and datasets, and opportunities for future collaborations.

IndianaView/AmericaView

The project to create Landsat thematic mapper data sets for each of the counties in Indiana was completed: http://www.indianaview.org/glovis/IN_County_Landsat_Data.html. The data sets represent a temporal sampling across 30 years for each of the counties. The data were obtained by Landsat 5 and also the most recent Landsat 8 sensors. These data sets were prepared to make it easier for teachers, students and the public to view and analyze Landsat images of their areas without have to download and manage full Landsat (~15 county scenes).

AmericaView sponsored an official Earth Observation Day (October 10) during Earth Sciences week. As part of this event, a poster was prepared by NASA/USGS/AmericaView about Landsat data including a Candyland type game; see Larry if you wish to have one. Also as part of this event, Larry prepared an online puzzle allowing the user to select many different images from Landsat data for the puzzle:http://indianaview.org/image_puzzle.html.

Grant proposals

The group worked with Prof. Shweta Singh of Environmental and Ecological Engineering and ABE, Purdue, and submitted a proposal aimed at creating an innovative, collaborative platform for developing and standardizing process modeling to help solve issues in a circular economy (e.g., recycling). Two other proposals are in the works.

Scientific Solutions in Byte Size (June-July 2017 issue)

TOTAL Camp

When their teachers ask what they did this June 11-14, the students in the Purdue Polytechnic Institute’s Turned Onto Technology and Leadership (TOTAL) camp will have a good answer – they spent a portion of the week learning about geospatial data with GABBs team. Using MyGeoHub’s MultiSpec image processing tool, TOTAL campers completed a hands-on exercise employing satellite imagery to calculate how much land had been impacted by a flood. This hands on session was lead by Larry Biehl with help from other GABBs team members.

HUBzero / GABBs ½ day Tutorial at PEARC

This tutorial organized around the recently added Jupyter and R Studio tools on HUBzero went smoothly and the hands-on exercises worked great on MyGeoHub. Martin Hunt, Derrick Kearney, Kevin Wojkovich and Rajesh presented the hands-on components and Carolyn lead the efforts to keep the teams coordinated. Thanks to the effort put in by the teams prior to the conference! This presentation has resulted in at least two inquiries of collaboration - potential new hub and hosting, and GABBs geospatial tutorial for high school students.

GABBs Packaging Session at PEARC

A paper on our experiences in moving GABBs to AWS was presented at the PEARC17 conference by Rajesh. AWS CloudFormation is now employed to enable a completely automated installation and configuration of GABBs, which includes a hub instance and other complementary software and servers. For more details, check out the GABBs release page: https://mygeohub.org/groups/gabbs/release. 

MultiSpec Poster winning Student Category 

Wei-Kang Hsu, graduate student working with Larry Biehl on MultiSpec Online, presented a poster about this work at PEARC17. His poster won the “People’s Choice Best Student Poster” Award. MultiSpec is a freeware image processing tool to analyze a broad spectrum of geospatial image data, with capabilities such as feature extraction, feature enhancement, supervised and unsupervised classification, and multi-dimensional data visualization.

GABBs presented at the IWSG

The GABBs development and outcomes were presented at the 9th International Workshop on Science Gateways, June 19-21. A pre-print draft of our paper can be found at https://mygeohub.org/resources/1318. It was a good opportunity to connect with researchers working on getaways and relevant technologies on both sides of the Atlantic and increase awareness of similar work going on in other groups (e.g. international consortium on science gateways). The other good news is that the tools on MyGeoHub ran quite well with good performance when Carol attempted them in Poland.

(Contact: Lan, Jaewoo Shin)

IsoMAP2 gateway deployed

With 1600 registered users worldwide, IsoMAP is an online workspace for spatial analysis, modeling and prediction of stable isotope ratio variation in the natural environment. IsoMAP consists of a suite of web-based GIS and software tools allowing users to easily explore, develop, and implement models for isotope distributions. The first version of IsoMAP portal was based on the Gridsphere framework which is no longer being maintained. The IsoMAP portal has been migrated to the Spring Java framework with improved functionality. The new portal was released in production in April. With the new phase II funding from NSF, new features will be created to support research on bird migration using isoscapes modeling (http://isomap.org). (Contact: Lan, Jungha)

HazardSEES project

Chris started consulting on the EvacSim project within the HazardSEES NSF program (PIs: S.V. Ukkusuri, Civil Engineering, M. Kulkarni, ECE) in April. This project investigates simulation of vehicular traffic in an urban area and, ultimately, helps decision makers plan and manage during emergency evacuations. Chris’ current role is to develop the communication protocol between the model and visualization programs so users can monitor the simulation real-time. He will also advise on software development best practices to help improve the simulation software developed to date by the group’s graduate students. The group currently tests the model with evacuation traffic patterns of Miami using 40,000 vehicles but hope to scale this to a more realistic 300,000 vehicle simulation before generalizing the project to handle other metropolitan areas. (Contact: Chris, Carol)
