Building Footprint Geometry for Local Government Basemaps

Ground-floor shapes and orientations for all structures within a local government jurisdiction, compiled from orthoimagery or aerial photography. This data supports government basemaps and is managed by data.nola.gov, with a recent update in December 2025.

Use Cases

• Analyze building density and urban form by calculating Shape.STArea() and Shape.STLength() for each footprint.
• Manage and validate site addresses by linking building footprints via the GEOPIN or StructureID fields.
• Support emergency response planning by mapping building locations and ActiveStatus using the_geom data.
• Track changes in the built environment over time by comparing OBJECTID or GlobalID records across data releases.

Strengths

• Includes geometric properties like Shape.STArea() and Shape.STLength() for quantitative analysis.
• Covers all structures within a local government's jurisdiction for complete spatial coverage.
• Data is actively maintained, with a recent update timestamp of 2025-12-30.

Limitations

• Sample size and total row count are unknown, making it difficult to assess dataset scale.
• The specific geographic coverage (city, county) is not explicitly stated in the provided metadata.
• Data quality details regarding positional accuracy or completeness of attributes like ActiveStatus are unavailable.
