Current published standards and specifications relating to static differential GPS surveys are outdated and have lagged behind technological developments. The standards and specifications should be revised to serve current user capabilities, and extended to encompass other GPS survey types, such as rapid static and kinematic surveys.

Currently, errors in the published charts, raw data, and data products have created a demand for third party groups to 'clean-up' the information. In the aviation industry, for example, third parties use aviation chart data as input in aviation products.

· NOAA should target some research to product development;. Most research outlined in the NSRS plan focuses on fundamental scientific research that does not directly support emerging or existing user groups.

Most communities that use GPS levelling require a geoid known to better than ten centimeters, although some require accuracies better than three centimeters. For communities that use conventional levelling, whether because a highly accurate geoid is unavailable or because they lack sufficient knowledge of the surveying profession to make use of it, additional bench marks are needed.

Standardizing the procedures will avoid duplication of effort and confusion between the user communities, and will also make the stations more cost-effective. Although NOAA need not certify all CORS or require that they follow established procedures and formats, it must ensure that the stations intended for public use are provided in accord with the appropriate standards.

The preface should also provide the context for creating a NSRS, namely the Executive Order on the National Spatial Data Infrastructure, and finally, a costs versus benefits analysis. GPS is a leading edge technology that is provided to the world by the U.S.

Such a cost/benefit analysis would include both a market survey and a marketing strategy. The market survey would not only provide an estimate of the economic benefits of NSRS, but would also include "success stories" to illustrate, In easily understood terms with dollar values attached, the societal benefits of an NSRS.

NOAA can foster partnerships with private industry to develop a "valueadded" business to serve particular user communities. The businesses would receive, at low cost, relevant data and information from NOAA, enhance it to meet specialized needs, and then sell it to the customer.

State Geodetic Advisors aid local governments and surveyors in the proper use of geodetic control, and by helping users to take full advantage of the GPS-based NSRS, they may indirectly bring economic benefits to the community. Examples of such local economic benefits include increased efficiency of local governments, prevention of waste from incorrectly implemented local GIS systems, and reduction of Federal Emergency Management Administration (FEMA)

effectiveness within the concept of a utility, and developed the following comments from the discussion: NOAA should design the NSRS to meet the needs of the larger user community. NOAA has an acknowledged commitment to serve the needs of the surveying and mapping communities, but it must recognize that these communities constitute only a small fraction of the potential user group.
