What we do

Collect, clean, and manage spatial information and datasets.

Visualize spatial information.

Conduct data analysis and reporting.

Design and build interactive web-based applications.

Develop workshops and trainings on spatial data research, design, and visualization.


Urban Open Data

UOD gathers the open data sites of cities and countries around the world into a single interactive map. The project grew out of our commitment to information sharing and thus reflects our contribution to fostering democratic access to publicly generated data.


PARCi is the Public Archive of Architecture and the City, a digital historical atlas of global urbanism. Architects, planners, preservationists, and researchers can use PARCi's fully-vectorized historical base maps and its analytical tools to generate qualitative and quantitative analyses of architectures and cities without having any GIS training.

Chicago Architects Project

Chicago Architects Project is an ongoing research project by the Society of Architectural Historians that serves to illustrate relationships among and between architects in the Chicago area. Studio Plat contributed to CAP by transforming a static genealogical tree into a dynamic web-based application that allows users to trace the lineage of Chicagoland architects and architectural firms.

Data Humanism by Design

We bring together humanists, technologists, and designers through our Data Humanism by Design (DHxD) workshops, public talks, and community events. The next DHxD workshop focuses on how to translate and visualize research questions for broad public audiences. Workshop participants can choose to attend either a single introductory session or an in-depth two-week module to learn interactive visualizations for qualitative research using HTML, CSS, and JavaScript. No previous coding or design experience necessary.
