Vertical aerial photography uses aerial cameras on flight platforms to capture vertical images, reducing field work and labor intensity, and is unrestricted by geography—images truly reflect surface morphology and textures. Equipped with POS systems, aerial cameras provide real-time position/attitude data, enabling ground feature measurement and production of digital outputs (e.g., digital raster maps, DLG, DEM, DOM).  Fast, precise, and cost-effective, it is widely applied in surveying, geology, hydrology, resource surveys, agricultural assessment, planning, route selection, and environmental monitoring, etc.

Oblique aerial photography overcomes limitations of traditional vertical photography, capturing multi-angle images simultaneously to obtain high-resolution textures on building tops and sides. It truly reflects ground features, captures high-precision textures, and generates realistic, measurable real-scene 3D models with advanced technologies. With high efficiency, precision, realism and low cost, it is widely used in smart cities, land planning, emergency intelligence, etc.
