We achieve the acquisition of aerial image data from different angles simultaneously, and obtain rich high-resolution textures on the top and sides of buildings. Tilt aerial photography can not only truly reflect the ground conditions and obtain texture information with high precision, but also generate realistic and measurable 3D models through advanced positioning, fusion and modeling technologies.

We use airborne LIDAR as an active remote sensing observation technology that integrates laser ranging technology and positioning and fixing technology. We can directly obtain high-precision three-dimensional coordinates and intensity of the surface of the ground by carrying an airborne laser scanner on board the aircraft. LIDAR is less affected by weather and natural environment. The measurement result of LIDAR is not affected by vegetation due to penetration and multiple echo characteristics.

We can obtain spatial, spectral and radiation information of the feature at the same time by carrying an imaging spectrometer on the flight. The imaging spectrometer has tens or even hundreds of bands compared with traditional three bands visible light RGB. The more the number of spectral bands, the finer the spectral profile of the feature can be obtained. Hyperspectral technology can use the spectral features between substances to identify different targets. It is widely used in the fields of ecological environment monitoring, mineral exploration, resource investigation and urban planning, etc.

The transmission window exist in seawater. The blue-green light with wave length of 0.47-0.58μm has the smallest attenuation coefficient in seawater. The airborne laser bathymetry system adopts the blue-green laser of 532nm wavelength as the laser transmitting light source to measure the depth of seawater according to the time difference between the reflection of the laser at the sea surface and the sea bottom. We can efficiently obtain a 3D topographic map of the seafloor in the flight path.
