Integration of LIDAR Data in CARIS HIPS for NOAA Charting

Abstract

The LADS based LIDAR system was used extensively for support of NOAACharting requirements along the Alaska Peninsula in 2001. The LADSMk.II Laser Airborne Depth Sounder system was operated in an extremelychallenging environment in conjunction with ship based operationsusing Reson 8101 and 8111 Multibeam echo sounder systems. It wasconsidered beneficial to NOAA to have both data sets available ina single product throughout the survey area so a converter was builtto read the LADS data into CARIS. This enables the LADS and multibeamdata to be compared and potentially merged to provide continuousdata from deep water to approximately 10 meters above the low waterdatum. The data is available in HDCS and hence all the HIPS qualitycontrol tools are available to the user. This paper briefly describesthe operations and focuses on how the two data sets were convertedand analyzed in CARIS HDCS.
