    "Building footprint and LiDAR height observations date to 2010; the static snapshot is not a current building survey. Geometry is budgeted to 7000 downtown and 4000 Presidio-region records, ordered by numeric height.",
    "LiDAR median height defines ordinary envelopes; high-rise maximum height is used only within a bounded range of the median. Roof shapes and facades remain schematic.",
    "Salesforce Tower and 181 Fremont are nominal modern landmark envelopes added because they postdate the 2010 survey. Coit Tower uses a nominal 64.6 m fluted column and observation arcade. Transamerica uses the survey footprint and nominal 260 m pyramid silhouette. Landmark profiles are authored, not surveyed facades.",
    "City street centerlines are real; road widths are class estimates and surfaces are draped over the terrain. Major bridges are modeled separately.",
    "Most park boundaries are city property polygons. Five woodland areas and deterministic canopy clusters are authored context informed by park descriptions, not retrieved vegetation observations or surveyed forest boundaries."
