About the Reviewers

Mark Cederholm, GISP, has over 20 years of experience in developing GIS applications using various Esri technologies, from ARC/INFO AML to ArcObjects to ArcGIS Runtime and Web SDKs. He lives in Flagstaff, Arizona.

He has been a technical reviewer for the book, Developing Mobile Web ArcGIS Applications, Packt Publishing.

Truc Viet Le is currently a PhD candidate in information systems at the Singapore Management University. His research interests primarily involve novel methods for the modeling and predicting of human mobility patterns and trajectories, learning smart strategies for urban transportation, and traffic flow prediction from fine-grained GPS and sensor network data. He uses R and Python every day for his work, where he finds R superb for data manipulation/visualization and Python an ideal environment for machine learning tasks. He is also interested in applying data science for the social work and international development work. When not behind the computer screen, he is an avid traveler, adventurer, and an aspiring travel writer and photographer. His work portfolio and some of his writings can be found on his personal website at http://vietletruc.com/.

He spent a wonderful year at Carnegie Mellon University in Pittsburgh, Pennsylvania, while pursuing his PhD. Previously, he obtained his bachelor's and master's degrees from Nanyang Technological University in computer engineering and mathematical sciences.

John Maurer is a programmer and data manager at the Pacific Islands Ocean Observing System (PacIOOS) in Honolulu, Hawaii. He creates and configures web interfaces and data services to provide access, visualization, and mapping of oceanographic data from a variety of sources, including satellite remote sensing, forecast models, GIS layers, and in situ observations (buoys, sensors, shark tracking, and so on) throughout the insular Pacific. He obtained a graduate certificate in remote sensing as well as a master's degree in geography from the University of Colorado, Boulder, where he developed software to analyze ground-penetrating radar (GPR) for snow accumulation measurements on the Greenland ice sheet. While in Boulder, he worked with the National Snow and Ice Data Center (NSIDC) for eight years, sparking his initial interest in Earth science and all things geospatial: an unexpected but comfortable detour from his undergraduate degree in music, science, and technology at Stanford University.

Julia Wood is currently a Geospatial Information Sciences (GIS) analyst who spends her professional time completing projects as a contractor in the Washington D.C. area. She graduated magna cum laude from the University of Mary Washington in Fredericksburg, Virginia, in the spring of 2014 with a bachelor's degree in both history and geography as well as a minor in GIS. Though her career is still in its early stages, Julia has aspirations to keep growing her skill set, and working on this review has certainly helped expand her professional experience; she hopes to continue learning and eventually work toward a master's degree while still working full time. In her non-work life, she enjoys reading, crafting, cooking, and exploring the big city, one local restaurant at a time.

Reviewing this book for Packt Publishing was Julia's first professional reviewing experience and she hopes that she can pursue similar endeavors in the future.

I'd like to thank my parents, John and Diana, for always encouraging me to do well in my educational and professional endeavors; my sister, Sarrina, and my brother, Jonathan, for offering support and advice when I needed it; and my boyfriend, Max, and my cat, Coco, for keeping me company while I conducted the reviews for this book. A thank you to Packt for letting me be a part of this experience!
