Digital Orthophoto Color and Infrared (DOP RGBI) Operat 2019350

An orthophoto is a distortion-free and true-to-scale image of the earth’s surface. Op-colors have been produced from analog (image flights with a median image scale of 1:15 000), since 2010 from digital aerial images (flights from 2010) in real color (RGB), false color (CIR — near infrared color range) or 4-channel images (RGBI). These orthophotos are produced in a soil resolution (pixel size) of 20 cm (from 2010) or 25 cm. This is one of a total of 29 operas, which together cover the territory of Austria.正射影像（orthophoto）是一种无畸变且比例真实的地表影像。该类正射影像的色彩数据最初由模拟航摄（平均影像比例尺为1:15000的航空摄影）生成，自2010年起则采用数码航空影像（2010年起的航摄任务）生成，涵盖真彩色（RGB）、假彩色（CIR——近红外色域）及4通道影像（RGBI）三种类型。该类正射影像的空间分辨率（像素尺寸）为20厘米（2010年起）或25厘米。本正射影像是覆盖奥地利全境的总计29组正射影像数据集之一。
