We plan to address state, local, and private aspects more fully in a following report. As previously stated, spatial information is in a period of transition between traditional paper records mostly maps-and sophisticated digits data bases.

It must cater to the needs of many different types of users and incorporate many types of data. If the potential dissemination of spatial data is to be realized, for example, then communication networks must be capable of handling a wide range of transmission speeds to accommodate everything from simple text to four dimensional animation.

Special tools for displaying and accessing geographically referenced information such as electronic atlases, also will be important in the NSDI. Data Networks The networks are the highways linking data bases and users in the NSDI.

There must be intelligent connections at each end, optimizing the management of the data bases at the source and maximizing the potential application of the data by users. In between there will be, for example, an array of common servers providing stanclardized information services to users, gateways and query languages regulating the data flow, and interfaces translating the data from one format at the source to another at the user's terminal.

by, for example, system vendors and network managers. Other standarcis, such as geographic referencing frameworks for data integration, must be specifical{y addressed in a spatial data context (e.g., Lee and McLaughlin, 1991~.

Commitment in terms of financing, policies, and resources must be obtained first at the federal level because it is a national strategy. However, it also will be important to convince policy makers and governments at other levels of the need for investment in the NSDT in the early organizational stages.

Determine Priorities From the evaluations of the requirements and current status, the next step will be to determine priorities. These will include priority data bases to be included in the NSDI, priority issues that need to be resolved, ant!

At this stage the issue of private sector involvement must be addressed at a policy and management level. Develop Standards and Policies A continuation of current research and coordination initiatives, particularly at the federal level, this stage will be crucial in determining the data bases that can be part of the infrastructure and in developing the information marketplace.
