Read the city. Test what changes.
Urban science connects form, fabric and outdoor conditions. Follow measured returns into a building stock, read satellite surface heat, then test how an example envelope changes a hypothetical day.
Sourced mapped overview
Loading the retained public observations.
Assembling the warm-day experiment in the background.
A return is an observation. The survey records points on roofs, trees and ground. The 3 m display thinning keeps actual returns; it creates no new measurements.
A surface is a representation. A common 5 m display grid brings the 1 m ground and surface products into one frame. Their dates differ from the point survey.
A building needs more evidence. Mapped footprints and a declared roof statistic make these volumes. Materials, windows, energy and heat loss need separate observations and models.
The survey header leaves its vertical datum unspecified, so alignment with the composite heights has not been independently qualified. The Thames uses an illustrative fixed water level; the wheel is a schematic at its mapped position. Roof reconstruction, calibrated thermal or flood results and aerial photography are not included.
