As NOAA pushes out on its ocean mapping goals, one promising effort in work is the development of a process for NOAA’s vessels to acquire ocean mapping data during transits. Using GIS for route planning against priority data layers, NOAA can make better use of standard transits between project areas to collect bathymetry, along with water column and acoustic backscatter data. Transit route surveys will provide an additional source of seabed mapping data to supplement current bathymetric coverage and fill in gaps where bathymetric data is scarce. With GIS and layers that indicate bathymetric grid cell data gaps, hydrographic surveying priorities and environmental compliance factors, NOAA can route plan much more effectively to make use of the transits between ports and projects. Keeping a database of routes taken can make the planning tool smarter, so that the next route can step over to collect a parallel line and avoid recollecting the same track.
