ADS40 - Progress in digital aerial data collection

After its introduction at the ISPRS Congress in Amsterdam in 2000 the LH Systems ADS40 Airborne Digital Sensor has undergone extensive final tuning, flight tests and calibration, culminating in first deliveries to customers in summer 2001. Recent tests have included investigations into the geometric and radiometric performance of all seven channels - three panchromatic and four multispectral - using imagery acquired at several flying heights over various types of terrain in Switzerland, Japan and Italy.
