Each building on this map carries a set of independently useful
readings. Switch colour to change which one is shown:
Typology: the building's likely use (residential,
commercial, industrial, etc). Typology rule shows which of
those were actually evidenced versus defaulted.
Height / footprint: estimated height and
footprint area. Not every value comes from a direct measurement, some
are calculated estimates. Click a building for its height
source to see which.
Earthquake risk: a relative seismic-risk rating (Low to
Very High) for the area a building sits in, based on public disaster
planning data. This describes the area, not a structural assessment of
any individual building.
Retrofit priority: how much a given area may benefit from
seismic reinforcement, on the same Low to Very High scale, combining
more than one independent signal - the same rapid-triage spirit as
FEMA P-154 screening, not a substitute for a real structural
assessment.
Green proximity: distance to the nearest mapped green
space, a standard proxy for local cooling potential.
Tree canopy: measured tree-canopy cover in the surrounding
area, independent of green proximity above (this counts actual canopy
anywhere, not distance to a park entrance).
Climate zone (LCZ): the Stewart & Oke Local Climate Zone
scheme, the standard international classification of local urban form
(how densely built, how tall) used by researchers and city planners
worldwide. It describes form, not a specific temperature.
Sky view factor: how much open sky is visible from street
level in an area. Lower means more enclosed by surrounding buildings,
which matters for heat and outdoor comfort.
