This document discusses automated solutions for survey validation and chart adequacy from NOAA and UNH. It introduces the Pydro Universe, a collection of open-source hydrographic tools, and Hydroffice, a research framework that facilitates transitioning research tools to operations. Hydroffice contains quality control and chart adequacy tools that perform tasks like finding outliers in survey data and comparing current surveys to ENCs. The document demonstrates some of these tools and asks which tool attendees would most like to see improved first.
