"Map once, use many times" has been a guiding principle at NOAA when planning data acquisition. But how do you determine the areas that will be most beneficial for the greatest number of stakeholders? NCCOS has used a collaborative GIS process to prioritize seafloor mapping needs. We have created a widget for the Web AppBuilder that can be configured to use either a high/medium/low or a token-based method to prioritize areas and additional selections to elicit the reason for their decisions.
