NEXT STEPS FOR TlIE USGS The USGS vision document (USGS, 2001) outlines a series of"next steps" in lieu of an implementation plan.

Although pilot projects are an important first step for testing ideas and approaches, potential partners in the broader geospatial community need an understanding of the specifics of how they could be involved, the benefits to them, and the resources they will likely need to contribute if they are to buy into the concept. There are few barriers for the USGS in creating such an implementation plan, and indeed, progress may already have been made beyond the documents circulated as part of the visioning process.

Rapid development of an implementation plan is critical because it watt increase the chance of leveraging existing data so that much can be accomplished in a short time. The initial version of the enhanced National Atlas would be the existing digital map holdings of the USGS, enhanced with public domain data from elsewhere in the federal government, such as TIGER, the National Shoreline database, and the BLM's Geographic Coordinate database.

The review stage of the USGS National Map vision has been open and available for each of these groups, primarily through the Internet but also through published outlets. There are many potential nontraditional partners who generate or use spatial data and should be involved.

The USGS's regional structure is a tier above that of the state, though the current pilot projects have a stronger state orientation (see Table 2.1~. The USGS vision document refers to area maintenance offices and field centers as two tiers that are envisioned for Me National Map.

Efficiencies and better coordination will be realized if USGS integration offices are managed in partnership with other state integration offices (such as state geographic information councils that currently perform interagency coordination functions) and other distributed federal offices and centers.

Can computers detect, recognize, and then automatically represent in spatial databases features captured in high-resolution imagery? Can automated methods be devised to detect, measure, and update changes over time?

From page 66... ...
Depending on how the databases are designed and how the content is specified, these resources could potentially serve most of the spatial data needs of local, tribal, state, and private sector, as well as federal users. The USGS will need to do a requirements analysis of existing and potential users to support its data quality goals.

Workshop participant William Craig suggested building on the NRC evaluation of FGDC partnership programs (NRC, 2001) that outlined responsibilities for data collection and maintenance (see Table 4.~.

SUMMARY The USGS's vision document proposes completion of Me National Map by 2010. To achieve this, USGS will need to work on product definition, specifications, and an implementation plan.
|
From page 70... ...
A user requirements assessment, perhaps conducted through the FDGC structure, wall increase project participation and buy-in and increase the value of the data holdings. An effective implementation plan will recognize that needs vary at the local tier, and that the focus should not be solely federal-down but also local-up.
