Abstract
The georeferenced digital library concept has considerably evolved during the last decade. From a simple repository of geospatial documents in the 1990s, this concept is now more in phase with a geospatial data access infrastructure, integrating various data discovery technologies and running in a Web environment. The integrated georeferenced digital library (IGDL) is an application working with the latest geospatial technologies like geospatial data warehouses, Internet map and imagery servers and automated geospatial data discovery Web services. The IGDL is no longer a unique application oriented solely towards geospatial data discovery. An R&D project aiming at developing an IGDL has been conducted at DRDC Valcartier between 2000 and 2004. Through this project, developed IGDL prototypes feature innovative aspects, like the partial automation of geospatial data inventory and metadata capture, the definition of complex and irregularly shaped areas of interest and the provision of direct access to native or Web-based geospatial data. This document introduces and describes the new concepts associated with the IGDL and positions it within a geospatial data infrastructure. It describes the project stages and emphasizes the guidelines that have oriented the development of the application. It concludes with descriptions of new development orientations for IGDL, including OLAP and peer-to-peer frameworks, which are used within new implementations of IGDLs for concept demonstration
