Geospatially Referenced Digital Libraries
Prof. Mike Freeston,
University of Aberdeen/UCSB, California
In this talk we discuss the design of digital libraries and their role as a
foundation on which to build the infrastructure for global knowledge
networking over the World Wide Web. The discussion is centered on the
experiences of a specific research program, the Alexandria Digital Library
(ADL) Project at the University of California, Santa Barbara, which has
developed an operational geospatially referenced digital library.
A defining characteristic of such a system is its use of the Earth metaphor
for describing, organizing, using, presenting, and evaluating information at
all levels of spatial and temporal resolution; i.e. everything is viewed and
categorized in terms of its location in space and time on the surface of the
Earth. This is a natural metaphor for answering questions of the kind:
'Where is.?'; 'What information/data does the library have about this area
of the Earth?'; 'Where can I find.?'; 'What happened where and when?'; 'What
would happen in this area if.?' It encompasses a vast number of potential
applications, from environmental planning and earth science education to
We begin by defining what we mean by digital libraries and geospatial
referencing. We then focus on the architecture and design of ADL: handling
metadata and data diversity, providing search access across diverse
collections, incorporating knowledge services such as gazetteers and
thesauri, and providing user workspaces for evaluation and use.
We discuss the concept of knowledge networking and how the World Wide Web
needs to change to support it. Finally we develop a knowledge-networking
scenario in a geospatial context to illustrate our vision of the path to the
