10 Years of Business and Mapping

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

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

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

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

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 ( 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

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.

Crossroads of Migration

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

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.
