Sociologist Roderick D. McKenzie taught at Ohio State in the early 1920s while completing his dissertation on the urban and neighborhood geography of Columbus. One of McKenzie's maps delineated themes common with the Chicago School of Sociology urban geography focus: race and ethnicity. McKenzie's data provides a snapshot of the racial and ethnic geography of Columbus in the early 1920s and is useful to compare to recent patterns of race and ethnicity (from US Census data) to assess urban social change.

Sanborn Fire Insurance maps contain a wealth of building-level information about U.S. cities dating back to the late 19th century. They are a valuable resource for studying changes in urban environments, such as the legacy of urban highway construction and urban renewal in the 20th century. However, it is a challenge to automatically extract the building-level information effectively and efficiently from Sanborn maps because of the large number of map entities and the lack of appropriate computational methods to detect these entities. This paper contributes to a scalable workflow that utilizes machine learning to identify building footprints and associated properties on Sanborn maps. This information can be effectively applied to create 3D visualization of historic urban neighborhoods and inform urban changes. We demonstrate our methods using Sanborn maps for two neighborhoods in Columbus, Ohio, USA that were bisected by highway construction in the 1960s. Quantitative and visual analysis of the results suggest high accuracy of the extracted building-level information, with an F-1 score of 0.9 for building footprints and construction materials, and over 0.7 for building utilizations and numbers of stories. We also illustrate how to visualize pre-highway neighborhoods.

This map layers shows refuse color day areas in the City of Columbus. These areas indicate the day of the week refuse is picked up from customers.

The pickup schedule for other customer types, such as 300-gallon container and dumpster customers, are simply identified by the day of the week collection occurs (e.g. Monday).

This layer depicts properties that have passed a lead clearance evaluation in the Lead Safe Columbus Program. The units shown were deemed lead-safe based on a lead clearance evaluation in the month shown. “Lead-safe” means that there was no deteriorated lead-based paint, no lead-contaminated dust, and no exposed lead-contaminated soil identified at the time of the lead evaluation. This does not mean that the units listed are vacant or available at this time. Please contact the owner of the property for rental information. With local and grant funding through the U.S. Department of Housing and Urban Development, Office of Healthy Homes and Lead Hazard Control, the mission of the Lead Safe Columbus Program is to generate lead-safe and healthy affordable housing and to prevent lead poisoning of children and adults in Columbus neighborhoods. This program may provide funding to eligible property owners for lead-based paint hazard control and addressing healthy homes hazards in tenant or owner occupied units.
