This paper expands discourse and methodologies for the scientific study of urban public spaces. It presents an analysis of observational data collected for the Fulton Area Business Alliance in Brooklyn, NY. Over the summer of 2013, two park spaces in Brooklyn were observed to determine the volume of use, the types of users, and the clustering patterns within the space. Spatial statistical analysis is performed to detect hot spots of activity. The study demonstrates that usage trends can be discerned through direct-observational techniques, and that fine-grain GIS analysis can assist in the formulation of and justification for new designs.
