Daytime thermal image (16/07/2023)

Daytime thermal aerial photography (georeferenced and orthorectified) acquired between 14:35 and 16:00 on 16 July 2023 on the entire urban area of Ferrara, as part of the USAGE European project. Thermal orthophoto is available in the geographical reference system EPSG:7791; each cell in the image has a numerical value (Band1) corresponding to the approximate temperature of the surface at that point (sensor temperature). — The acquisition took place via air flight carried out by AVT Airborne Sensing Italia, with Dual-Digi Therm 1024 thermal chamber of IGI mbH. The images were radiometrically corrected, converted to temperature in degrees Celsius, projected onto the digital model of the ground and mosaicd.本数据集为2023年7月16日14:35至16:00期间，针对费拉拉（Ferrara）整个城区获取的日间热红外航空摄影影像（经地理配准与正射校正），属于USAGE欧洲项目的组成部分。该热红外正射影像采用EPSG:7791地理坐标系；影像中的每个像元均包含一个数值（波段1），对应该点位地表的近似温度（传感器测温值）。本次数据采集由意大利AVT航空传感公司（AVT Airborne Sensing Italia）执行，搭载IGI mbH公司的Dual-Digi Therm 1024热红外相机舱。所有影像均已完成辐射校正，转换为摄氏度温度值，投影至地面数字模型并拼接为整体影像。
