The orthophotomosaics are a composition of individual orthophotos, in principle of the central parts of each orthophoto. As a result, the overturn in the mosaics has been kept as small as possible. The orthomosaics are nationwide.
Within the service, 3 layers per year are offered during the construction phase. About a month after the final layers became available nationwide, the two 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（orthophotomosaic）由单幅正射影像（orthophoto）拼接而成，原则上选取每幅正射影像的中心区域，以此将镶嵌图的拼接错位量控制在最低水平。本数据集的正射影像镶嵌图覆盖全国范围。
该服务在建设阶段每年提供3个图层。在全国范围内最终图层上线约一个月后，两款快速正射影像图层将停止提供服务。
- 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RGB快速正射影像（临时图层）
