Dr. Zhenlong Li is elected as the Vice Chair of the Cyberinfrastructure Specialty Group(CISG) of the Association of American Geographers(AAG) for year of 2018-2019. He will assume the Chair role for the second year.
The AAG CISG strives to enhance geographic research and scholarship on matters relating to cyberinfrastructure. For more information about CISG, visit: http://gis.cas.sc.edu/cisg
Organized by the US Geospatial Intelligence Foundation and open to the 14 GEOINT accredited universities, the challenge asked applicants to describe which problem they would choose to solve if given access to to an NVIDIA GPU-powered supercomputer. Ning’s winning essay, submitted with USC Geography professors Zhenlong Li and Cuizhen “Susan” Wang, was titled “Tagging the Earth with High Resolution Imagery and Deep Learning.”
In announcing the winners, Dr. Camelia Kantor, USGIF’s Director of Academic Programs, noted that the winning entries “stood out because they made a strong case for using the GPUs for the benefit of their students.”

Aims and Scope
Rapid onset disasters, often difficult to prepare for and respond to, make disaster management a challenging task worldwide. Disaster and emergency management effectiveness depends heavily on making good decisions in near-real time under extreme duress. These key, often life-saving, decisions are possible only with real-time data sources and the ability to timely collect, process, synthesize, and analyze these multi-sourced data. Traditional data collection practices such as remote sensing and field surveying often fail to offer timely information during or immediately following damaging events. For example, stream gauges are only useful for flood mapping while the stations are functioning properly and before they are overtopped by floodwaters and rendered inoperable.
Fortunately, sharing information such as texts, images, and videos through social media platforms enables all citizens to become part of a large sensor network and a homegrown disaster response team. Compared to traditional physical sensors, such a citizen-sensor network (social sensing) is low cost, more comprehensive, and always broadcasting situational awareness information. For example, with social sensing, massive amounts of micro-level disaster information (e.g. site specific damage) can be captured in real-time through social media platforms (e.g. Twitter, Facebook) and voluntarily reported via dedicated crowdsourcing applications (volunteered geographic information, VGI), enabling rapid assessment of evolving disaster situations.
On the other hand, data collected with social sensing is often massive, heterogeneous, noisy, unreliable, and comes in continuous streams. This is inherent “Big Data”, for example, millions of microblog posts from different social media platforms can be generated in a short time right after an impactful disaster. Hence, Big Data computing methods and technologies such as cloud computing, distributed geo-information processing, spatial statistics/modeling, data mining, spatial database, and multi-source data fusion become critical components of using social sensing to understand the impact of and response to the disaster events in a timely fashion.
Along these lines, this special issue on “Social Sensing and Big Data Computing for Disaster Management” by the International Journal of Digital Earth aims to capture recent advancements in leveraging social sensing and big data computing for supporting disaster management in one or more disaster phases (mitigation, preparedness, response, and recovery). Specifically, we solicit original unpublished research articles that can shed light on the opportunities, challenges, and solutions of leveraging social sensing and big data computing for supporting disaster management.
Potential topics include (but are not limited to) the following:
- Innovative approaches to synthesize multi-sourced social sensing data and/or traditional data (e.g. remote sensing) for disaster management
- Analyzing and visualizing human movement patterns before, during, and after disaster events
- Disaster event detection, early warning, and impact/damage assessment with social sensing
- Mining and extracting actionable information for rapid emergency response and relief coordination
- Geovisual analytics of social sensing data during a disaster
- Integrating data mining (machines) and crowdsourcing (human) to support decision-making
- New tools and solutions for real-time big social sensing data collecting, processing, analyzing, and visualizing
- Exploring public perception, sentiments, and understanding towards disaster events
- Novel social engagement approaches to effectively link the public in an organized way toward contributing to emergency response, recovery
- Data quality, reliability, and privacy issues of social sensing for disaster management
- Leveraging big social sensing data to enhance social resilience

Dr. Zhenlong Li’s research on using social media for flood mapping is highlighted in Charleston City Paper. Full story can be found here:
Dr. Zhenlong Li and his student Yuqin Jiang’s research on the use of Twitter data to track solar-eclipse viewing in South Carolina was featured on the local ABC broadcast affiliate.

Dr. Zhenlong Li’s research on using social media for flood mapping is highlighted in Charleston City Paper. Full story can be found here:
“Researchers also looked at the use of social media during and after the floods. Zhenlong Li studied the use of Twitter for quickly mapping the flood based on what people were tweeting and from where. He found a high correspondence between the number of tweets from a specific location and the level of flooding.
