Mapping Urban Change in Harrisburg, 1900–1930

Harrisburg's City Beautiful movement dramatically transformed the urban landscape between 1900 and 1930 through the installation of new roads, water systems, and parks, and the dislocation of the communities of the Old Eighth Ward. This article applies different geospatial analytical techniques—hexagon overlay, kernel density, mean center, and directional distribution—to visualize Harrisburg's population distribution during this period and to map its growth and movements in response to these changes.
