An Architecture and Operation Model for a Spatial Digital Library
Overview The dependency on and importance of spatial data is well documented but the reality is that a majority of spatial data is inaccessible, even to the most experienced user. The reasons for this situation include the lack of a general and national locator service; facilities to retrieve, convert, relate, and access spatial data; and a diversity of standards for cataloging and representing spatial files. A national spatial digital library would greatly improve this situation. This paper presents a model for a distributed, hierarchical architecture to support a spatial digital library. The goals of this work are to clarify and resolve the problems of access by creating a national spatial metadata locator service that supports the collection and distribution of metadata to geographically distributed nodes. A unique aspect of this approach concerns the distribution network, which is built upon traditional institutions, particularly libraries, at the state and local levels.
