How does it impact Clemson students?

Through this recognition, students at Clemson using GIS for their research are allowed special access to Esri software for their projects, get additional training, and the possibility to attend the Esri Developer Summit in Palm Springs, California.

Additionally, students are encouraged to participate in the Annual Outstanding EDC Student of the Year award. 

Student of the Year Award

The EDC Student of the Year is an annual award open to all Clemson students. The winner will be recognized as Student of the Year for outstanding achievements in development of innovative tools, applications or techniques using ArcGIS platform. Each year the winner will be awarded with a plaque, cash prize, and one Esri Developer Summit registration.


All undergraduate and graduate students at Clemson University in any discipline are eligible for the award. Students demonstrate innovative use of the ArcGIS platform in their application.


In 2019, the Clemson Center for Geospatial Technologies was designated an official Esri Development Center. Later in 2021, the program ​name changed to Esri Development Program and was awarded to the entire Clemson community. 

This special recognition is only awarded to a small number of leading university entities across the world that have exemplary programs focused on educating students to design and develop innovative applications based upon the ArcGIS platform.

2021 Clemson Student of the Year: Jacob Arnold


Jacob Arnold is a Ph. D candidate in Environmental Engineering at Clemson University. His research revolves around sustainability and resilient infrastructure systems, studied through holistic modeling to determine vulnerabilities and avoidable environmental impacts.

His main research project is specifically focused on the impact of the coal transportation industry and the infrastructure it relies on. More specifically, his analysis aims to demonstrate the alternative problems associated with coal transportation.


Through incorporating multiple network line datasets, ArcGIS Pro routing, and empirical data on coal transactions and emissions, GIS models of how coal flows through the US as well as the associated emissions have been developed.

Below is an overview of his project, from the manual data gathering phase that leads into automation made possible with ArcGIS Python notebooks. Each feedback loop indicates at least one scenario where tool output informed on changes necessary for steps and data managed earlier in the workflow.

The foundation for such an ambitious model is constructed from national-scale data on two important aspects of the coal transportation network: nodes and connecting lines.


Nodes consist of the origin points of every US coal mine active during the study period of 2008 to 2018 as well as the destination points of US coal-burning power plants, likewise active during the same time span.


The lines which connect these nodes together represent the three major modes of transportation available to coal in the US: railroads for freight trains, highways for freight trucks, and waterways (rivers and ocean routes) for barges.


Finally, to facilitate a multimodal connection between each of these three networks, another set of nodes is implemented to represent various transition terminals, such as barge-loading stations next to railroads.


Across each of these maps, this model demonstrates the double-edged sword that is the US coal industry.


Focusing on the high-traffic areas through Nebraskan railroads, combined with the fact that coal is still a major component of the US fuel mix, high vulnerabilities are a detriment to the resilience of the national energy infrastructure.


While fortification is normally recommended in these scenarios, this model also demonstrates the resulting greenhouse gas emissions of coal in these high traffic areas and beyond.

2020 Clemson Student of the Year: Abi Roberts


Abi is a senior environmental engineering student at Clemson University. For the past year, she worked with the Clemson Center for Geospatial Technologies on a variety of projects, including creating web mapping applications and building dashboards with WebApp Builder for ArcGIS. 


One of her main projects involved a collaboration with Greenville City Police Department and their Strategic Planning and Analysis Division. The goal of this project was the use of geospatial data analytics to increase their efficiency in resource allocation using big data. In particular, the Division was interested in better understanding the distribution and frequency of operations.


In order to achieve this, over 3 million records of their patrol vehicles' positional data were analyzed over space and time. To determine if a particular police car was stationary or moving, Abi created her own Python scripts in ArcGIS Pro that computed the difference in time and space between each two consecutive GPS locations for each patrol vehicle, as well as the frequency of places visited by the time of day and day of the month.

She then created a dashboard that answered specific questions such as which streets were most frequented, for how long, and the time of day visits occurred.


In order to create this dashboard, she used HTML and CSS to customize the information efficiently and appealingly.

The Police Department Strategic Planning Division were able to visualize and analyze the geographic distribution of their fleet, the frequency of places visited and the reliability of their new tracking system.

2019 Clemson Student of the Year: Justin Dowd


Justin is a senior in Clemson University’s School of Computing as well as a Senior Intern in the Clemson Center for Geospatial Technologies.


He has been been working with researchers in the Department of Environmental Engineering and Earth Sciences who are exploring the potential for rooftop solar photovoltaic (PV) deployment in South Carolina. The project aims to identify suitable locations for rooftop solar across the state using remotely sensed imagery (e.g. aerial and/or satellite imagery) and machine learning coupled with CyberGIS.


An initial assessment of Clemson's main campus has already been conducted, which identified a number of high-value locations. Justin is expanding on that analysis using known building footprints on campus and other training data to conduct supervised image classification to identify and calculate suitable rooftop area across the entire state of South Carolina.


Justin has developed and tested workflows for parallel computation to scale the analysis from the small test region to the entire state while exploring several GIS platforms: Esri ArcGIS Pro, GRASS GIS, and Google Earth Engine. Using a variety of imagery and additional data sets, he is testing each of these platforms to:

  • Evaluate the accuracy of the machine learning algorithm implementations

  • Identify the best combination of input data for most accurate rooftop identification

  • Determine the most efficient method of scaling the computation on each platform


The imagery data are the United States Department of Agriculture National Agriculture Imagery Program (NAIP) 1-meter resolution data, both a 3-band true-color image from 2017 and a 3-band multispectral image from 2009, the most recent year available for the area.

Justin is incorporating 1-meter resolution elevation data derived from the South Carolina Department of Natural Resource’s LiDAR database, where possible, to improve the classification accuracy, although this is not supported in GRASS GIS.

The Support Vector Machine (SVM) algorithm is utilized in ArcGIS Pro and Google Earth Engine, whereas the Maximum Likelihood algorithm is used in GRASS GIS as the SVM method is not implemented in the base software package.


The results presented in the table below show the percentage of buildings on Clemson University’s main campus correctly classified in each platform and with different combinations of imagery and elevation data. The classification accuracy is only considered for buildings present in all input data sets to remove the impact of construction and demolition over time.

Justin is discovering that each platform offers its own advantages and challenges. Google Earth Engine scales automatically without any change in workflow, though it is limited by the computational resources allocated to the free accounts. ArcGIS Pro gives the highest overall accuracy but is limited by the computing resources of a desktop computer. It does not operate natively in a Unix environment typical of high performance computing (HPC) clusters and has many limitations which reduce potential efficiency in a high throughput computing environment. GRASS GIS is producing the lowest overall accuracy, but runs on UNIX systems, meaning the workflow can be parallelized and scaled efficiently on an HPC cluster, such as Clemson University’s Palmetto Cluster.

Justin will continue to work on this project through and hopes to incorporate deep learning methods to improve the classification results. Other projects he has worked on at the Center for Geospatial Technologies include writing scripts to deploy Structure from Motion (SfM) software in parallel on the Palmetto Cluster to efficiently process photos from UAVs into a variety of geospatial data.
