Aerial view National Facilities Imagery (2016) WMS

The orthophoto mosaics are a composition of individual orthophotographs, basically of the central parts of each orthophoto. As a result, the fall in the mosaics has been kept as small as possible. The orthophoto mosaics are landscaping. Since 2016, in addition to the final web service Ortho10, there is also a web service Quick_Ortho10. There is also a web service Quick_Ortho25 in addition to the web service Ortho25 available under Open Data. The images in both Quick_Ortho layers are geometrically of sufficient quality and become available accelerated, but colors and cutting lines are not yet optimal. The final web services Ortho25 and Ortho25IR are open data from 2016 onwards and are offered in a separate WMS. Within the service, 3 layers per year are offered during the construction phase. About a month after the final layers become available, both Quick-Ortho layers are no longer available. — High resolution quick-orthophoto under the name Quick_Ortho10 (temporary layer) — High resolution orthophoto under the name Ortho10 — Low resolution quick-orthophoto (RGB) under the name Quick_Ortho25 (temporary layer)正射影像镶嵌图（orthophoto mosaic）由单幅正射影像拼接而成，核心区域取自每幅正射影像的中心部分，以此将镶嵌过程中产生的偏差控制在最小范围。该类影像为地表景观正射影像数据。 自2016年起，除正式Web服务（Web Service）产品Ortho10外，同步推出Quick_Ortho10临时Web服务。针对开放数据渠道下的Ortho25服务，同样配套提供Quick_Ortho25临时Web服务。两类Quick_Ortho图层影像的几何精度已满足要求，可快速上线发布，但色彩表现与拼接裁切线仍未达到最优标准。 正式Web服务产品Ortho25与Ortho25IR自2016年起纳入开放数据范畴，通过独立的网络地图服务（WMS, Web Map Service）对外提供。 在服务建设阶段，每年将提供3个年度图层。待正式图层上线约1个月后，两类Quick_Ortho临时图层将停止服务。 — 名为Quick_Ortho10的高分辨率快速正射影像（临时图层） — 名为Ortho10的高分辨率正射影像 — 名为Quick_Ortho25的低分辨率快速正射影像（RGB格式，临时图层）
