District of Columbia Impervious Surface Basemap for 2023

District of Columbia provides a 2023 basemap dataset classifying impervious surface features. It captures structures like airport taxiways, helipads, buildings, sidewalks, roads, alleys, and swimming pools. The data supports stormwater management and urban planning analyses.

Use Cases

• Analyze the spatial distribution of impervious surface types like buildings and roads for stormwater runoff modeling.
• Map the location of specific features such as airport taxiways and helipads for infrastructure asset management.
• Calculate total impervious surface area from the basemap to assess environmental impact on water systems.

Strengths

• Data is current, captured in the year 2023.
• Covers a specific, well-defined geography: the District of Columbia.
• Available in multiple geospatial formats including GEOJSON, KML, and ArcGIS REST API for flexibility.

Limitations

• No row or column count is provided, making the dataset's scale and feature detail unknown.
• Sample data is unavailable, preventing preview of attribute structure and data quality.
• The specific methodology for feature capture and classification is not described.
