The CAMCATT-AI4GEO extensive field experiment took place in Toulouse, a city the southwest of France, from 14th to 25th June 2021 (with complementary measurements performed on 6 September 2021). Its main objective was acquisition new reference dataset an urban site support development and validation data products future thermal infrared (TIR) satellite missions such as TRISHNA (CNES/ISRO), LSTM (ESA) SBG (NASA). With their high spatial (between 30-60m) temporal (2-3 days) resolutions, TIR will allow better investigation climate at neighbourhood scale. However, order validate these LST, air temperature, comfort index Urban Heat Island (UHI), there is need accurately characterise organisation terms 3D geometry, spectral optical properties both land surface temperature emissivity (LST LSE) several scales. In this context, campaign provides set airborne VISNIR-SWIR (Visible Near InfraRed - ShortWave InfraRed) hyperspectral imagery, multispectral imagery LiDAR acquisitions, together with variety ground collected, for some them, simultaneously flight. includes reflectance measured spectrally ASD spectroradiometers six bands spreading shortwave two viewing angles SOC410-DHR handheld reflectometer.
