TIERED APPROACH TO WENS
The WENS principles encompass a wide variety of data types categorized into three tiers based on principles outlined by UN-GGIM IGIF. This paper proposes a tiered approach for marine data to align with geospatial information principles for enhanced data management and interoperability.

TIERED APPROACH TO WENS CONSIDERING THE UN-GGIM INTEGRATED GEOSPATIAL INFORMATION FRAMEWORK PRINCIPLES
The WENS principles will be expansive in nature, including a wide variety of data types that must accommodate principles that range from more to less stringent depending on the intended use of the data, the source of the data, frequency of updates, method of distribution, and other factors. This paper proposes to divide marine data into three basic categories that aim to conform to three levels of principles. PRINCIPLES FOR GEOSPATIAL INFORMATION
UN-GGIM INTEGRATED GEOSPATIAL INFORMATION FRAMEWORK (IGIF) https://ggim.un.org/IGIF/part2.cshtml
IGIF PRINCIPLES ARE AGREED UPON AT THE UNITED NATIONS Examples Pathway 4 Standards: Appropriate and recognized standards are adopted and enforced throughout the data lifecycle to enhance integration and interoperability of individual and disparate data sets. Pathway 4 Metadata: Appropriate metadata is applied according to standards and used to accurately define and describe geospatial data, including content, geographic extent, purpose, characteristics, currency and provenance etc., together with contact details for further information. Pathway 2 Secure and Safeguarded: Ensure secure and trustworthy data sharing, dissemination and use. Geospatial information are stored, maintained and accessed in a secure environment and through secure methods. Pathway 1 Accountability: The responsibility for the decisions and laws that affect the strengthening of geospatial information management rests with government and is responsive to stakeholders needs and is in the interests of the community. Pathway 7 - Leadership, commitment and empowerment: Leadership and commitment is necessary to sustain a collaboration or partnership through ownership of purpose, empowerment in processes and collective responsibility for outcomes.
Category 1 data would include the most stringent, regulated data types such as S57 and S101. It would be categorized under the principles outlined in the UN-GGIM IGIF with a subset of additional principles specific to those outlined in the original WEND Principles. THREE-TIERED APPROACH Category 2 data would be less stringent, including weather, current, and other data that would only only apply to the principles outlined in the UN-GGIM IGIF Category 3 data would be the least stringent and wouldn t have any principles that apply. These would include crowd sourced, non-IHO, and other unofficial data.
Determining which data types belong in each tier Refining the information in tier 1 narrowing the old WEND Principles so the are not duplicating IGIF Principles but are strengthening the principles that are most important, overlaps, gaps, distribution, etc. THE MAJOR WORK WITH THIS APPROACH
