Inspire Download Service (predefined ATOM) for data set ATKIS — DOP20 (2009)

Description of the INSPIRE Download Service (predefined Atom): Aerial photographs are a photographic image of the landscape. They show a real picture of all objects visible from a bird’s-eye view, such as the road network, the construction, water and vegetation, as well as location-free objects such as cars that were at the site taken at the time of recording. Due to the special imaging conditions (central perspective), an aerial image, unlike a map, does not have an exact uniform scale. When photographing from the air, the differences in altitude in the terrain result in deviations in position. These are increasing sharply towards the edge of the picture. Through computational equalisation and digital image processing, digital orthophotos (DOPs) are created from the original aerial images, which represent the Earth’s surface in a true-to-scale and georeferenced manner. — The link(s) for downloading the records is/are generated dynamically from Get Map calling a WMS interfaceINSPIRE下载服务（预定义Atom格式）说明：航空摄影影像是对地表景观的摄影成像作品，可呈现鸟瞰视角下所有可见地物的真实样貌，涵盖道路网、建构筑物、水体与植被，以及拍摄时刻位于该区域的无固定位置地物（如车辆）。由于采用中心透视的特殊成像原理，航空摄影影像与地图不同，不存在精确统一的比例尺。空中拍摄时，地形高程差异会导致地物位置出现偏移，且偏移程度会向影像边缘急剧增大。通过计算校正与数字图像处理技术，可从原始航空摄影影像生成数字正射影像（Digital Orthophotos, DOPs），该类影像可按真实比例尺对地表进行地理参考化表达。—— 数据集记录的下载链接通过调用Web地图服务（WMS）的Get Map操作动态生成。
