The Technology and methodology of airborne laser bathymetry are far from mature, and new capabilities continue to be attained. The SHOALS lidar system was recently augmented with the ability to utilize kinematicGPS(KGPS) with on-the-fly(OTF) phase ambiguity resolution in order to permit the system to be used more extensively over land, for shoreline and other topographic mapping, in addition to underwater bathymetry. The seamless integration of these capabilities permits continuous surveying across the land/water boundary. Importantly, this also permits the production of sea bottom and topographic elevations without the need for concurrently measured water-level data. Algorithms and porcedures associated with the use of OTF KGPS are presented along with examples of performance.
