CUNY Mapping Service

The CUNY Mapping Service at CUR engages with foundations, government agencies, businesses, nonprofits, and other CUNY researchers to use spatial information and analysis techniques to develop and execute applied research projects. The project is directed by Steven Romalewski, who joined the Center for Urban Research in January 2006.  Our team includes Will Field, Valerie Bauer, and other graduate students over the years.

The Mapping Service is highlighted in the CUNY Master Plan 2016-2020 [PDF] as an example of how the Center for Urban Research is one of several research centers whose work helps further CUNY's expertise in urban issues. (see pp. 93-94 of the Master Plan)

We specialize in the development of online applications that provide intuitive access to powerful data sets, displayed visually through interactive maps and in other formats. Recent examples include:

Maps supporting a fair and accurate Census 2020 count. CUR is working with a coalition of civil rights groups, philanthropic foundations, and others to map "hard to count" communities in advance of the 2020 Census. The maps will help organizations to highlight the importance of having Congress fully fund the Census Bureau leading up to the 2020 Census, and to help "Get out the Count" campaigns prior to Census Day in April 2020.

  • This two-page summary [PDF] describes the maps, how you can use them, and other resources for advocates supporting the 2020 Census.
  • Launched October 2017.

  • using spatial analysis techniques to assist CUNY, government agencies, businesses, and nonprofit organizations to undertake strategic planning;
  • furthering the development of the OASIS NYC partnership;
  • consulting with groups in other cities engaged in similarly collaborative web-based projects;
  • enhancing the delivery of other interactive online mapping applications;
