My interest in data visualization centers on the use of geographic information systems (GIS) and 3D modeling. I am particularly interested in using these technologies and their related methodologies to explore the past. This includes a long-standing interest in issues of inequality and minority disenfranchisement. My interest in collaborative approaches to studying the past motivates my exploration of virtual technologies. My Deviant Art gallery includes past and ongoing projects.
This post concerns the visualization of property values. I am working on this for an upcoming project on the African American experience in Asbury Park, New Jersey, and particularly the 1970 riot. Part of this research focuses on the socioeconomic experiences (e.g., access to property ownership, property values) of various groups ithroughout the 20th century. Property ownership remains part of the “American Dream” and lured African Americans to many northern locations, places promising a more equitable society. A promised often denied.
One goal for this project explores geovisualization. Geovisualization, short for geographic visualization, is the visual representation of geospatial analyses. This increasingly involves the creation of interactive displays to share location-specific data. This post is not a nuts-and-bults how to, but it does outline the general steps and process for producing some interesting images of property values.
One of my primary interests as a geographic information systems (GIS) educator is exploring new ways of teaching GIS, and spatial analysis in particular. Lessons about network analysis and habitat modeling are some of the most difficult to explain because of their technical nature – not to mention the complicated process of arranging and changing data to accomplish various analyses.
This is the first post in a general effort to be more active in regards to my blogging activities during 2011. This post is inspired by two things; my research into race riots as part of my larger PhD project, and a recent New York Times article about tracing New York’s shifting ethnic population. You can view the newspaper article here.
The following five images show general population growth across Detroit during a 40 year span. This period marked rapid and profound changes in the racial make-up of Detroit. A large influx of African Americans from the US South has long been seen as one of several causes for racial strife in the city. The growing racial intolerance degenerated into racially charged collective violence in 1942 and 1967 when race riots occurred.
The following images were made with ArcGIS 10 using shapefiles and population extracts from the US census. This informaiton is free to download at the National Historical GIS. Each dot represents 100 individuals. I apologize for using black and white colors to represent Euro and African Americans, but it works for a quick visualization like this one. I have also included the total population and numbers of black and white residents in Wayne County for each year (source: US Census).
