10 Years of Business and Mapping

Unpublished

The Harvard Business School's Baker Research Services and Center for Geographic Analysis share a strong cross center collaboration.   This relationship was initiated by Sarah Ericksen, who reached out to CGA for mapping services nearly 10 years ago. 

This map showcases a few of the numerous mapping projects performed for various HBS faculty resulting from this BRS/CGA kinship, and is meant to serve as a commemorative tribute to Sarah, who is retiring in June of 2016. Scroll down to view locations and map samples that are the fruit of this relationship. 

Whale Watch Story Map

Unpublished

For our 2015 CGA staff outing we went on a whale watch out of Boston Harbor.  Here is a story map with geotagged photos and our GPS route.

People and Geography Quiz

Unpublished

The purpose of this web mapping application is to understand how well people can define locations of different groups in geographic space, and how this relates to their attitudes about towards these groups. Using two simple datasets such as US block groups and US zip code, an US basemap by Esri, and a classic web survey approach, the application asks users to indicate in which neighborhood do most people from a certain group lives. A side-by-side mapping approach is used to retrieve feedback once the survey is completed. 

Health Insurance Marketplaces

Unpublished

Prior to the Affordable Care Act, most states’ markets for individual health insurance were dominated by one or two insurer carriers and health plans. A principal goal of the Affordable Care Act is to encourage more carriers to compete in the new marketplaces and to offer plans that provide greater value to consumers. 

Rusian Genealogy Map

Unpublished

The Rusian Genealogy Map is an attempt to render visually the dynastic connections made between the ruling family of Rus’ (the Volodimerovichi) and the rest of medieval European royalty in the eleventh and twelfth centuries. The information represented on the map comes from the Rusian Genealogical Database (genealogy.obdurodon.org) compiled by Christian Raffensperger, with technical assistance by David J. Birnbaum. Both projects highlight the extreme interconnectivity of Rus’ with the rest of medieval Europe and are part of a larger goal of reimagining medieval Europe.

 

The Chinese Late Ming Dynasty Courier Route System

Unpublished

The Chinese Late Ming Dynasty Courier Route System application calculates the total distance between postal stations, the number of postal stations visited, and the number of counties (circa 1911) that were crossed. You can select postal stations from the pull-down menu or pick them by clicking on the map. Click the gear icon  to calculate a new route and the trash icon to clear an existing route.

Harvard in Africa

Unpublished

The CAS (Committee on African Studies) interactive web map visualizes the number of students by country in Africa for 2012 and 2013. Also, a pie chart is associated to display the purpose of travel and school affilation. Get the source code here: https://github.com/gzambotti/cas_fusiontable

 

Crossroads of Migration

Unpublished

The Crossroads of Migration map visualizes the movement of migrants from origin to destination countries. It is based on standardized 2013 United Nations data, a compilation of demographic reports from 232 countries.

U.S Cluster Mapping

Unpublished

The U.S Cluster Mapping is a web mapping prototype made for the Institute for Strategy and Competitiveness at the Harvard Business School, to display groups of interconnected companies, universities, and related institutions that arise out of linkages or externalities across industries.

Increasingly International Harvard: 1991-2010

Unpublished

Increasingly International Harvard: 1991-2010 is a web mapping prototype to display over time the increase of Harvard International student from 1991-2010 by school. The application is built using Google Map API and Google Fusion Table.

Digital Atlas of Roman and Medieval Civilizations (DARMC)

Unpublished

The Digital Atlas of Roman and Medieval Civilization (DARMC) makes freely available on the internet the best available materials for a Geographic Information Systems (GIS) approach to mapping and spatial analysis of the Roman and medieval worlds.

US Emergency Departments

Unpublished

US Emergency Departments — was created using the National ED Inventory-USA, a comprehensive database consisting of all non-specialty EDs. Users can select  options on the right to view different aspects of US emergency care. The web map was built using Google Map API and Google Fusion Table.

Boston Youth Tobacco Initiative

Unpublished

A map made for this project with photos, data and links.

Rwanda Genocide Memorials

Unpublished

Professor Jens Meierhenrich of Harvard’s Department of Government, in cooperation with CGA, launched an interactive website in support of a multi-year project on genocide memorials in Rwanda. By showcasing original geographic, ideographic, and photographic data collected in the field, the website provides a fascinating glimpse into the ongoing project, and affords a heretofore unavailable, GIS-aided perspective on the spatial dimensions of memory in the wake of collective violence.

Geographic Location Finder

Unpublished

Click, drag, and drop the red marker on any location. The updated latitude, longitude coordinates of its location are displayed.

Surgical Safety Web Map

Unpublished

CGA created a web map for the Harvard School of Public Health researcher team led by Dr. Atul Gawande involved with the World Health Organization "Safe Surgery Saves Lives" challenge. The goal of this challenge is to improve the safety of surgery around the world by defining a core set of safety standards that can be applied in all WHO member countries. The web map is a Google mashup, featuring participating organizations, hospitals, a global surgical rate map, and more.

G. W. Skinner Maps

Unpublished

Selected datasets from G. W. Skinner's regional systems analysis of China and Japan are available for browsing online, using the CGA Worldmap Platform.   See also the permanent Data Repository and the documention website.

China Historical GIS (CHGIS)

Unpublished

The CHGIS project has produced a comprehensive series of datasets related to the administrative geography of Chinese History. The data layers include nationwide coverages (for the years 1820 and 1911), and time series (for the Dynastic period from 221 BCE to 1911 CE). The administrative features include Provinces, Circuits, Prefectures, and Counties as they changed over time. Supplemental datasets include G.W. Skinner regional systems, Buddhist sites, features from historic Russian maps of China, Tibetan townships, modern gazetteer layers for each province, and many others.

GIS Data Portals

Philippines Typhoon Haiyan 2013 Data Portal

Unpublished

CGA creates Typhoon Haiyan Data Portal in support of geospatial information exchange for relief and reconstruction efforts after Philippines' super Typhoon on November 7, 2013.

Haiti Earthquake Data Portal

Unpublished

CGA creates Haiti Earthquake Data Portal in support of geospatial information exchange for relief and reconstruction efforts after Haiti's 7.0 magnitude earthquake on January 12, 2010.

Chile Earthquake Data Portal

G. W. Skinner Data Archive

Unpublished

An archive of the datasets developed for the Regional Systems Analysis laboratory, under the direction of G. William Skinner.

The core datasets, including GIS layers and tabular data, are being preserved in this repository. Together the datasets will present a case study of the methodology used for determination of the Levels in Urban Hierarchy (LUH), Urban-Rural Continuum values (URC), and the delineation of Core Periphery Zones (CPZ).

Japan Earthquake Data Portal

Unpublished

In response to the Tohoku Earthquake and Tsunami (Mar 11th 2011), CGA established a rapid response data portal.   With funding from the Reischauer Institute for Japanese Studies, the data layers were uploaded to an online webmap portal, where a number of additional data layers have been archived.
