Geographic Information Systems (GIS) have become increasingly popular among historians. Various online research sources are using GIS to show history in a new and interesting light. Geographic Information Systems is used in history to show data in a special context. By adding data to a map layers can be created to show the frequency of different events or compare similar events that happened in different areas of the world. Instead of looking at history in a chronological manner, GIS allows historians to look at the past in a different way. GIS creates a visual. In Writing History in the Digital Age, Stephen Robertson explains how he developed Digital Harlem, a GIS site that explores the history of Harlem.
Digital Harlem started with the organization of different black newspapers that were popular in the area. The newspapers were scanned and then categorized based off of the events that were seen throughout every single article. The events were then charted on a map based off of the address that accompanied the article. Crime for example, was broken down further into the charge that was pressed. Not only was crime charted but other events were as well. Parades, different sporting events, and even night clubs were placed on the maps. Robertson states in his chapter that looking at the map of night clubs map him think differently about the history of Harlem. He states that nightclubs and speakeasies were usually accompanied by white patrons. Buffet flats were more for just black customers. Mapping black nightlife “helps identify an unrecognized black response to Prohibition’s impact on Harlem: the creation of places apart from whites who appeared in increasing numbers in the neighborhood’s nightlife” states Robertson.
GIS sites such as Digital Harlem allows the user to search for specific events in Harlem’s history. You can then create different layers and have them placed on a map of Harlem. This technology opens doors for historians. We can more easily look at differences and similarities of different spaces during the same historical time period.
