Digital Orthophotos 50 cm grey Brandenburg — DOP50g (1992-1997)

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 DOP50g was part of ATKIS. The output scale is 1: 10 000. The ground resolution or pixel size is 1.00 m x 1.00 m (254 dpi = 100 L/cm). Delivery in grey scale, cut-free or 10 km x 10 km tiles; 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 10 km in one direction, the total area is divided into 10 km x 10 km tiles. 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）是经数字均衡处理的航空影像，以平行透视视角完整记录拍摄时刻空中可见的全部地物与相关信息，在生态、物候、地理等领域拥有较高的信息密度。DOP50g为ATKIS数据集的组成部分，其输出比例尺为1:10000，地面分辨率（像素尺寸）为1.00m×1.00m（254 dpi = 100 L/cm）。该数据以灰度影像形式交付，可提供无裁切整幅数据或10km×10km分幅瓦片；支持采用ETRS89（GRS80，UTM影像）坐标系，也可转换为其他参考坐标系。通过地理数据代理（geobroker）交付的数据无需裁切分幅。若待交付区域的单方向尺寸超过10km，则需将总区域拆分为10km×10km的瓦片。数据可通过自动化流程免费获取，或由用户自行采集。使用该数据时，必须遵守其许可协议条款。
