This paper describes the development of a set of interactive web based preview tools for enhancing the data discovery process to aid the metadata search facilities offered by the North East Environmental Data Server (NEEDS). NEEDS is a multi-tier environmental data clearinghouse based at the University of Newcastle upon Tyne, UK. The research outlined above demonstrates an implementation of the ArcSDE--Java API to enable the NEEDS data browser to catalogue and preview ArcSDE data-sources. Due to the variable nature of environmental data, a requirement was identified to offer a single integrated view of multiple source and format datasets, allowing users to visually detect implicit relations between datasets. The catalogue is presented as HTML with visual previews as interactive Java Applets. This paper will discuss the lessons learned during the development process and the authors' suggestions for extending the ArcSDE--Java API.
