Orthophoto Hydrographic Network River Rhine 2021 NIR

Four-band ortho-images displayable in color in NIR (near infrared), with average pixels of 15 cm. The acquisition of the images was carried out in the period 13 and 15 October 2021; cartographic cut: elements at 1:5.000. Territory concerned: Hydrophraphal lattice of the Rhine River. For the Rhine it was considered an area (buffer area) of 500 meters compared to the main arginal summits, both on the right and left hydraulic, for the Samoggia and Lavino Torrents a buffer area of 500 meters compared to the axis of the lean hive, while for the Ghironda Torrente, Navile Channel, Diversivo Channel, Savena Abandoned Channel and Napoleonic Cable a buffer area of 300 meters always with respect to the axis of the hive.本数据集包含可通过近红外（Near Infrared, NIR）波段实现彩色合成显示的四波段正射影像，平均像素分辨率为15厘米。影像采集工作于2021年10月13日至15日期间完成；制图裁切比例尺为1:5000。本次数据集覆盖莱茵河水系水文网格区域。针对莱茵河，以其左右两岸的主河岸边缘高地为基准，向外划定500米的缓冲区范围；针对萨莫贾河（Samoggia）与拉维诺溪（Lavino Torrents），以其河道中轴线为基准，划定500米的缓冲区范围；而针对吉龙达溪（Ghironda Torrente）、纳维莱渠（Navile Channel）、迪韦尔西沃渠（Diversivo Channel）、萨韦纳废渠（Savena Abandoned Channel）与拿破仑水道（Napoleonic Cable），则以其河道中轴线为基准，划定300米的缓冲区范围。
