Providing data adhering to IHO standards for hydrographic surveys (SP44 and SP52) for navigational chart products with ELAC's Bottom Chart Compact System

The Royal Danish Administration of Navigation and Hydrography (RDANH) is using two software packages from AlliedSignal ELAC-Nautik. Both packages are still undergoing development to achieve the maximum from the Bottom Chart Compact (BCC) system. As everyone involved with data from any multibeam system are aware of the time saved during data analysis and processing can be spent acquiring new data. Therefore, it is necessary to optimize all analytic and processing tools in order to leave the surveyor with a minimum time attended during these processes. Last year RDANH used a proportion of time between analysing/processing and data collection in the order of one to one. The time used has now for a skilled surveyor come down to half the time processing spent during data collection.
