GIS, Parcel & Zoning Data Integration
Developed a property-level geospatial data workflow integrating parcel geometry, assessor records, zoning information, coordinates, land-use attributes and other spatial layers. The work focuses on resolving disparate geographic records to canonical properties, validating spatial relationships, standardizing zoning and dimensional information, and creating analysis-ready datasets for property, land-use and development research.
