Undersea Cables: The Ultimate Geopolitical Chokepoint, Bert Chapman

FORCES Initiative: Strategy, Security, and Social Systems

This work provides historical and contemporary overviews of this critical geopolitical problem, describes the policy actors addressing this in the U.S. and selected other countries, and provides maps and information on many undersea cable work routes. These cables are chokepoints with one dictionary defining chokepoints as “a strategic narrow route providing passage through or to another region."

Odt Flow: Extracting, Analyzing, And Sharing Multi-Source Multi-Scale Human Mobility, Zhenlong Li, Xiao Huang, Tao Hu, Huan Ning, Xinyue Ye, Binghu Huang, Xiaoming Li

Faculty Publications

In response to the soaring needs of human mobility data, especially during disaster events such as the COVID-19 pandemic, and the associated big data challenges, we develop a scalable online platform for extracting, analyzing, and sharing multi-source multi-scale human mobility flows. Within the platform, an origin-destination-time (ODT) data model is proposed to work with scalable query engines to handle heterogenous mobility data in large volumes with extensive spatial coverage, which allows for efficient extraction, query, and aggregation of billion-level origin-destination (OD) flows in parallel at the server-side. An interactive spatial web portal, ODT Flow Explorer, is developed to allow users …

The Use of Geographic Information Systems in Territorial Diagnosis: an Applied Model on the Accessibility of Educational Services in the Zerhoun Cluster

The article discusses the issue of geographic information systems being limited by geographic researchers, despite being widely relied upon, to employment in the field of machine cartography only; in an attempt to highlight the many and varied capabilities offered by these systems. It is an effective, if used properly, tool in territorial diagnosis and an effective contributor to developmental construction.

Extending Arda: Mapping Beyond The Lord Of The Rings And Silmarillion, Stentor Danielson

Journal of Tolkien Research

The canonical maps by Christopher Tolkien from The Lord of the Rings and The Silmarillion cover only a small portion of the world of J.R.R. Tolkien's legendarium. In the years since their publication, many artists have been inspired to try to create maps of the entire world. In doing so, they have both curated the canonical information provided by Tolkien as well as engaged in their own sub-creation, drawing on geographical ideas from the primary world. This paper examines a broad set of fan-made maps of Arda to trace the lineages of their geographical conceptions and the principles behind their …

Military Cartography’S Influence On Tolkien’S Maps Of Middle-Earth, Stentor Danielson

Journal of Tolkien Research

The published maps of Middle-earth by Christopher Tolkien drew on extensive drafts made by his father during the process of his writing. These drafts enable tracing the possible influence of the elder Tolkien’s training in map-reading during his time in the British Army during the First World War. The early maps drawn by J.R.R. Tolkien exhibit features, such as the use of hachures and contour lines to indicate elevation, and a focus on the accurate calculation of distances and movements, that were characteristic of military cartography. The maps then evolved into a more pictorial style, characteristic of contemporary literary maps, …
