Rayonnement thermique des toituresRoof thermal radiation
This dataset published by the Geneva territorial information system (SITG) classifies roof heat loss into six levels, derived from thermal infrared imagery captured by a helicopter-mounted camera. Data were acquired at an altitude of 500 metres, flying at 70 to 120 km/h, using a thermal infrared camera centred on a 9.75 micron wavelength. The resulting thermal information supports the identification of poorly insulated roofs across the canton of Geneva, Switzerland, useful for energy efficiency assessment and building renovation planning.Classification en 6 Levelx des déperditions thermiques des toitures mesurées à l'aide d'une caméra embarquée sur hélicoptère.
