Digital orthophotos 20 cm colored with infrared channel Land Brandenburg — DOP20rgbi (2013-2015)

Digital orthophotos are digitally equalised aerial images and represent all air-visible objects and facts at the time of recording in parallel perspective. They have a high density of information on ecological, phenological, geographical and other topics. The DOP20rgbi are color images with additional infrared channel. The output scale is 1: 5 000. The highest possible ground resolution or pixel size is 0.20 m x 0.20 m (635 dpi = 250 L per cm). The data is also delivered at a lower price in 0.4 m and 1 m pixel size. Delivery in colour with infrared channel (RGBI, 32 bit), as color infrared (CIR, 24 bit) or as black-and-white infrared (8 bit), non-leaf cut; ETRS89 (GRS80, UTM image) or transformation into other reference systems possible. Data delivery via the geobroker is free from sheet cutting. If the size of the area exceeds 2 000 m in one direction, the total area shall be divided into 2 000 m x 2 000 m tiles. In doing so, the pixels are set white outside the area section. The data is provided free of charge via automated procedures or by self-collection. When using the data, the license conditions must be observed.数字正射影像（Digital orthophotos）是经过数字匀光校正的航空影像，以正射平行透视投影完整记录了拍摄时刻空中可见的全部地物与地理要素，信息密度极高，可支撑生态、物候、地理等多领域的研究与应用。其中DOP20rgbi为带有额外红外通道的彩色影像，输出比例尺为1:5000，最高地面分辨率（像素尺寸）可达0.20m×0.20m（对应635每英寸点数（DPI），即每厘米250线对）。该数据还提供像素尺寸为0.4m与1m的版本，售价更为低廉。 交付格式可选择带红外通道的彩色影像（RGBI，32位）、彩色红外影像（CIR，24位）或黑白红外影像（8位），均采用非分幅裁切模式；支持使用1989欧洲大地参考系（ETRS89，基于GRS80椭球体的通用横轴墨卡托影像（UTM影像）），亦可根据需求转换至其他大地参考坐标系。通过地理数据中介平台（geobroker）交付的数据无需进行图幅裁切。若待交付区域的单方向尺寸超过2000米，则需将总区域划分为2000m×2000m的瓦片，此时区域外的像素将被置为白色。该数据可通过自动化流程自助获取，或线下自行领取，全程免费。使用该数据时，请务必遵守相关许可协议条款。
