1999 NCMP Lidar and Imagery: Ala Moana Beach Park, Oahu, HI POC: Benton Ching
JALBTCX performs operations, R&D in airborne bathymetric lidar and complementary technologies in support of navigation, regional sediment management and environmental monitoring requirements of USACE.
Lidar (and imagery! Hyperspectral!) use in USACE is expanding and supports a variety of inland and coastal applications.
Exploitation of these data streams results in sophisticated information products that should be delivered in an easily ingestible and understood form (i.e. web services and web applications).
