Intensity images from the echoes of the Lasercsanner measurement — Free State of Saxony

As a complementary product, intensity images are created in laser scanner measurement. All objects of the Earth’s surface have different spectral reflection properties due to their physical properties. This depends on the intensity at which the laser beam is reflected. A grayscale image, the so-called intensity image, is derived from the intensity information of the reflected laser beam echo. The existing intensity images were generated from the intensities of the first and only echoes.
