Orthophotomosaic, middle-scale, winter recordings, colour, 2020, Flanders

The agency Information Flanders annually commissions to create an area-covering mid-scale orthophoto coverage of the Flemish Region, including the Brussels-Capital Region.This assignment is carried out in two phases: first the realisation of digital photographic aerial images in the winter flying season with a ground resolution of 17 cm and, then, the production of an orthophoto mosaic with ground resolution of 25 cm.This product is a compilation of the orthophoto mosaics (winter shots) collected for each part of this area in 2020.The product is supplemented by a dataset ‘fly day contour’ showing the recording date for each part of the compilation.法兰德斯信息署（Information Flanders）每年委托实施弗拉芒地区（含布鲁塞尔首都大区）的全域覆盖中比例尺正射影像（orthophoto）覆盖项目。该项目分为两个阶段推进：首先在冬季飞行季采集地面分辨率为17厘米的数码航空摄影影像，随后制作地面分辨率为25厘米的正射影像镶嵌图（orthophoto mosaic）。本数据集为2020年该区域各分区采集的冬季航摄正射影像镶嵌图的汇编成果。本数据集配套提供‘飞行日期轮廓（fly day contour）’数据集，用于标注该汇编各分区的影像采集日期。
