5. Why So Difficult Dark Target Spectroscopy Water is an extremely dark target compared to land targets. In addition, water attenuates signal exponentially with depth, at different rates per wavelength.

6. Why So Difficult Spectral Resolution in Shallow Water Depth = 6.5 m IOP = Case 1 Bottom = soft coral Depth = 13 m IOP = Pure H 2 0 Bottom = sponge

7. SAMSON: Spectroscopic Aerial Mapping System with On-board Navigation SAMSON provides full HSI dataset 256 bands in the VNIR (3.5 nm resolution) at 75 lines per second (pushbroom imager), with a SNR, stability, dynamic range, and calibration sufficient for dark target spectroscopy. SAMSON includes an Trimble Applanix DSS/POS AV system for RGB digital aerial photography data (framing imager) with direct geo-positioning. The HSI/RGB system is mounted on a 3-axis stabilized mount (100 Hz adjustment), and the position error of the RGB system is less than 1 pixel (<15 cm at nominal operating altitudes).

8. SAMSON Highlights SAMSON represents a geospatial sensor suite for automated feature extraction. Our hardware and software enables the automated rendering of intelligence from remotely sensed radiance in near-real time. Production time of 1 TB of raw imagery data (6 hours of continuous collection) to ortho-rectified products is less than 8 hours.
