Coast Survey is developing a project to create a comprehensive spatial database of hydrographic surveys. This database will be unique in that the survey data will be corrected for differences in horizontal and vertical datums in order to provide a uniform data set. Such data has been used to produce combined bathymetric/topographic maps that can be used for inundation modeling for studying the effects of sea level rise, tsunamis, or storm surge. |
Tools will eventually be developed to more easily produce gridded data sets supporting navigational products. These tools will allow Coast Survey to use the most modern, high-resolution multibeam and LIDAR surveys in combination with older, single-beam data to produce more consistent and detailed navigation products. Eventually, the system will house both historic data in the spatial database and the newer surveys in a grid database, thus creating the Bathymetric Warehouse. |
