The IRIS airborne integrated LiDAR hyperspectral imaging system is a higher order airborne hyperspectral remote sensing solution independently developed by IRIS. By integrating real hyperspectral data and higher quality orthorectified data, and utilizing a joint analysis platform for terrain stereo morphology information and spectral information, we provide users with higher quality spectral remote sensing data.

With the help of an external push scan imaging spectrometer, it is possible to obtain true hyperspectral data (rather than frame based band splicing spectra) with incomparable spectral sampling intervals and true spectral resolution, which is the foundation for accurate remote sensing applications.

With the help of line scanning LiDAR, surface elevation can be obtained, which enables extremely accurate orthorectified calibration of images. At the same time, the three-dimensional shape information of ground objects can also be obtained, and combined with spectral information analysis, opening up a new research perspective.

Compared to using separate LiDAR and hyperspectral imagers separately for data synthesis, the IRIS all-in-one machine has significant advantages.

The two sensors in the all-in-one machine are in a rigid system, and after calibration, there is no error in coordinate conversion during the use of DEM;

The IRIS laser radar system provides higher elevation accuracy, with a horizontal accuracy of ± 2cm and an elevation of ± 1cm;

Besides DEM, elevation and shape data can be analyzed together with hyperspectral data to achieve more functions;

√ Lower procurement and operating costs (fewer flights) and higher measurement efficiency.
