Orthophotographie infrarouge 2012 de la Métropole de Lyon

Infrared aerial orthophography is produced by the setting in geometry and the association of shots from aerial photography. This shot is made with a multi-channel sensor (Red, Green, Blue and near Infrared). The production of infrared images is carried out by association of the Red, Green and Near Infrared channels (the Blue is removed). This data covers the 1.300 km² on the Grand Lyon and its surroundings. The assembly board makes it possible to locate the 6 slabs of approximately 300 km² (according to the grid RGF93 CC46) to the pixel of 0.10 m.红外航空正射影像（Infrared aerial orthophography）通过对航空摄影影像开展几何校正与拼接关联处理生成。该类影像由搭载红、绿、蓝及近红外多波段传感器的航空设备拍摄获取。 红外影像的生成流程为保留红、绿、近红外三个波段，剔除蓝波段后通过波段关联合成得到。 该数据集覆盖大里昂（Grand Lyon）及其周边共计1300平方公里的区域。 借助影像拼接处理平台，可将6块面积约300平方公里的影像区块（依据RGF93 CC46坐标系网格）实现0.10米分辨率的像素级地理定位。
