In practice, new edition cycles are influenced by the number and type of critical corrections affecting a chart, remaining shelf stock, receipt of new basic data, format or regulation changes, and most of all by the availability of financial resources. Critical corrections include, but are not limited to, those to aids to navigation, obstructions, shoaling, facility changes, and dredging.

This requires coordination of two branches within the Nautical Charting Division of the Coast and Geodetic Survey: the Charting Branch, which handles chart requests, and the Hydrographic Surveys Branch, which handles survey requests. Sixty percent of the survey data used in the compilation of NOAA's present nautical chart suite comes from surveys that were completed prior to 1940, with technology that was much less accurate for determining position than that now in use.

Army Corps of Engineers has successfully evolved from exclusive use of in-house crews and equipment for data acquisition to use of contract crews and equipment for roughly 40 percent of the hydrographic survey data presently acquired. The Corps of Engineers uses a formal selection process to select technically qualified contractors based on merit from a list of respondents prior to any price considerations.

The success of cooperative endeavors with other organizations depends on several factors: the resolution of liability requirements, adoption of agreed-upon standards, technology development, training of cooperative groups, and availability of some additional resources for use by the Coast and Geodetic Survey in monitoring these joint ventures. Cooperative ventures are now becoming more innovative, especially as federal resources shrink, technology changes, and the demand for graphic and digital data becomes more pervasive.

Since many of NOAA's critical (it emergency If) requests to investigate reported navigation hazards occur in or near these major commercial navigation projects, these resources could be readily deployed to perform surveys.
