This repository serves as a comprehensive metadata catalog for NYC GIS datasets maintained by the Office of Technology and Innovation. It does not contain actual geospatial data or processing code, but rather detailed documentation describing over 30 NYC GIS datasets including 3D building models, address points, aerial imagery, building footprints, transportation networks, and environmental data. Each dataset is documented in a consistent markdown format covering identification (purpose, source, update frequency), data quality specifications (coordinate system, resolution, accuracy), and attribute information (for vector datasets). The repository functions as a reference for understanding what GIS data is available from NYC, its characteristics, and how to access it.
