Global Spatio-Temporal Search: NEH Funded Enhancements to WorldMap With a grant from the National Endowment for the Humanities, the CGA is building a platform to create, maintain, and deploy a global public registry of web map services, and has developed a new visual interface to support searches by time and space. The technology can scale to millions, even billions of objects. Read more | |
Dynamic Mapping of Secondary Cities Workshop A 1.5-day workshop is scheduled for the Mapping Secondary Cities for Resiliency, Human Security, and Emergency Preparedness project sponsored by the NGA and State Department. The project is managed by CGA visiting scholar Dr. Melinda Laituri, who is working with the team to plan an international workshop at Harvard on June 14-15 this year. This day and half workshop will focus on open source geospatial tools and technologies for mapping Secondary Cities. The aim of the workshop is to bring together organizations and individuals involved in innovative mapping activities and solutions for emergency preparedness, resiliency planning, and urban sustainability. Secondary Cities are rapidly growing urban areas that are regional hubs for commerce, services, and governance in developing countries that are often inadequately planned for future development and growth. The workshop will open with a half-day session to provide a hands-on venue to explore and assess online, open sources tools for mapping and creating geospatial date for cities. The full day sessions will include: 1) Secondary Cities overview; 2) Case studies of dynamic city data collection; 3) Interactive assessment session of tools as linked to emergency preparedness, resiliency planning, and urban sustainability; 4) Solutions/Lessons learned. See more information and register (for free) here. | |
HARVARD GIS COMMUNITY NEWS | |
Harvard Map Collection Update The Map Collection has recently licensed the Mobil Coverage Explorer dataset from Collins Bartholomew. This product shows aggregated 2G (GSM), 3G and 4G (LTE) mobile coverage on a global basis. The polygon data is in ESRI shapefile format. The Map Collection has also licensed postcode point data for Greece, Slovenia, Croatia and Albania. The datasets will be made available through the Harvard Geospatial Library soon, but are currently available to Harvard Affiliates in the Map Collection reading room in Pusey Library. A recent paper map purchase includes part of a series of maps of the “Greater East Asia Co-Prosperity Sphere”, a propaganda concept created by Imperial Japan in 1940. The maps are in Japanese at various scales, and cover parts of China, India, Myanmar (then Burma), New Zealand and other countries. The maps will be cataloged and listed in HOLLIS. | |

2016 GIS Poster Expo at Tufts University The 10th annual Tufts GIS Poster Expo is a campus wide exposition of the GIS work being done at Tufts. There will be over 170 posters submitted by students, faculty and staff. This is an excellent opportunity for students to showcase their work, see what classmates in various disciplines have completed with GIS. 3:30-5:00pm, Wednesday, May 11th, 2016. Alumnae Lounge, Aidekman Arts Center 40 Talbot Ave, Medford Campus. | |

Presentation slides. View a recording of the presentation.
Bio: Kelly O’Neill is a historian of Russia. Her research and teaching interests concentrate on the evolution of the tsarist empire, and particularly on the social, cultural, and spatial implications of imperial rule. Her first book, Southern Empire: the Logic and Limits of Russian Rule in Crimea, reconstructs the incorporation of the peoples, places, and institutions of the Crimean Khanate into the Russian system. The book challenges the binary terms in which imperial rule has traditionally been understood - i.e., the language of center and periphery - and reveals a more complex, more flexible spatial framework. Her work on Crimea has engendered an abiding interest in the Black Sea world, leading her to projects on the slave trade, the development of the Russian wine industry, and the management of natural resources - above all, forests – in the 18th and 19th centuries. O’Neill directs the Imperiia Project - a historical GIS of the Russian Empire that examines Russia’s cultural and commercial infrastructure.
Lunch will be served.

Abstract: Apache Lucene/Solr is a wildly popular search library and search server. But it does more than keyword search; it has impressive spatial/geospatial search capabilities too. After a brief overview of search technology, I’ll tell you about these spatial capabilities with examples, mostly in Solr. I’ll then cover some exciting advances that have occurred recently in Lucene and planned features, not yet exposed in Solr. Some of the more recent interesting capabilities are multi-dimensional indexes, surface-of-sphere/ellipsoid geometries, and heatmaps.
Speaker: David Smiley is a freelance consultant and software developer specializing on search technologies with Apache Lucene/Solr. David is a committer and PMC member with the Apache Lucene/Solr project and he co-wrote the first book on Solr – Apache Enterprise Search Server (PACKT), now in its third edition. Within the code-base, David is most known for developing much of the spatial code, and for establishing the Spatial4j library that some of Lucene uses. He’s native to Massachusetts, residing in Lowell. He has a Bachelor’s degree in Computer Science from Northeastern University.

Human migration has been an important activity in human societies since antiquity. Since 1890, approximately three percent of the world’s population has lived outside of their country of origin. As globalization intensifies in the modern era, human migration persists even as governments seek to more stringently regulate flows. Understanding this phenomenon, its causes, processes and impacts often starts from measuring and visualizing its spatiotemporal patterns. This study builds a generic online platform for users to interactively visualize human migration through space and time. This entails quickly ingesting human migration data in plain text or tabular format; matching the records with pre-established geographic features such as administrative polygons; symbolizing the migration flow by circular arcs of varying color and weight based on the flow attributes; connecting the centroids of the origin and destination polygons; and allowing the user to select either an origin or a destination feature to display all flows in or out of that feature through time. The method was first developed using ArcGIS Server for world-wide cross-country migration, and later applied to visualizing domestic migration patterns within China between provinces, and between states in the United States, all through multiple years. The technical challenges of this study include simplifying the shapes of features to enhance user interaction, rendering performance and application scalability; enabling the temporal renderers to provide time-based rendering of features and the flow among them; and developing a responsive web design (RWD) application to provide an optimal viewing experience. The platform is available online for the public to use, and the methodology is easily adoptable to visualizing any flow, not only human migration but also the flow of goods, capital, disease, ideology, etc., between multiple origins and destinations across space and time.

Without a department of geography, Harvard University established the Center for Geographic Analysis (CGA) in 2006 to support research and teaching of all disciplines across the University with emerging geospatial technologies. In the past four and a half years, CGA built an institutional service infrastructure and unleashed an increasing demand on geographic analysis in many fields. CGA services range from helpdesk, project consultation, training, hardware/software administration, community building, to system development and methodology research. Services often start as an application of existing GIS technology, eventually contributing to the study of geographic information science in many ways. As a new generation of students and researchers growing up with Google Earth and the like, their demand for geospatial services will continue to push CGA into new territories.
