National Hydrography Framework Standard Develop formal Content Standard for Hydrography. –describe a general model (a data dictionary, definitions, relationships) application-independent, supports international standards facilitates the exchange of data.

Geospatial One-Stop Key points: –To provide fast, low cost, reliable access to geospatial data needed for government operations –To facilitate interactions needed for vertical missions such as Homeland Security –To establish a methodology for obtaining multi-sector input EGOV Initiative

Geospatial One-Stop Key points (continued) –Develop and implement Framework Data content standards Elevation Orthoimagery Hydrographic Data Administrative Boundaries Transportation Networks Cadastre Geodetic Control –Establish comprehensive Federal Portal –Managed by John Moeller, FGDC & Scott Cameron, DOI with great interest from Mark Foreman, OMB EGOV Initiative
