True or False: Airborne lidar can simultaneously scan both land and water in a coastal zone.

Airborne lidar technology is capable of simultaneously scanning both land and water surfaces, especially in coastal zones where these environments intersect. This is achieved through the use of different wavelengths of laser light which can penetrate water to varying depths while also providing detailed topographic data for the land. The multi-spectral capability of airborne lidar systems allows them to collect precise elevation data over both environments in a single flight, making it an efficient tool for comprehensive coastal mapping.

The effectiveness of airborne lidar in achieving this depends on several factors, including the lidar system's specifications and the water clarity; however, generally, such systems are specifically designed to operate efficiently across diverse landscapes. This adaptability and capability to gather data without needing multiple passes is a significant advantage in hydrographic surveying and environmental monitoring.
