University of Miami Institute for Data Science and Computing. last updated: 2024-10-28 (update frequency: As Needed). Abstract: A polygon feature class of property boundaries in Miami-Dade county sourced from the Miami-Dade Open Data Portal and then augmented with elevation data, flood zone data, qualified opportunity zone boolean, water overlap as boolean, managed areas (parks), intersections with major roads, and both county and municipal zoning information. All of the augmentation is based on spatial joines. Please see the ETL and provenance documentation for more information.
