Description
New York City's parcel-level Geographic Information System land cover layer classifies pervious and impervious surfaces across all five boroughs. The dataset, developed by the City of New York's Department of Environmental Protection (DEP), supports stormwater-related planning and is accompanied by a 2020 webinar and presentation. It is distributed as five separate geodatabases, one for each borough, with a total citywide file size of 4.60 GB.
Use Cases
Analyze impervious area percentage at the parcel level to model urban stormwater runoff and plan green infrastructure placement.
Compare land cover classification and pervious area across the five boroughs to assess spatial patterns of urban permeability.
Use the parcel-level GIS layer to support regulatory compliance and planning for stormwater management as referenced in the DEP's 2020 study materials.
Strengths
Provides citywide coverage for all five boroughs of New York City.
Includes supporting materials such as a recorded webinar and presentation from June 2020 explaining the study.
Data is structured at the parcel level, offering granular spatial detail for land cover analysis.
Limitations
The data is provided solely for informational purposes with a disclaimer regarding accuracy for other uses, requiring independent verification.
Specific data volume metrics like row count and column schema are unknown, limiting precise assessment of dataset scale and structure.
The data's temporal coverage and update schedule are not specified, potentially affecting its currentness for time-sensitive applications.
