-------- Original Message -------- Subject: Georeferencing & Geospatial Digital Libraries: Tutorials at the 2003Joint Conference on Digital Libraries (fwd) Date: Mon, 28 Apr 2003 20:07:52 -0500 (CDT) From: Lisa Colleen Sweeney <[log in to unmask]> To: <[log in to unmask]> ------------------ Georeferencing & Geospatial Digital Libraries: Tutorials at the 2003 Joint Conference on Digital Libraries The 2003 Joint Conference on Digital Libraries will feature two tutorials of interest to the GIS community: "Introduction to Georeferencing in Digital Libraries" and "How to Build a Geospatial Digital Library." The tutorials will take place Tuesday, May 27 at Rice University in Houston, Texas. The deadline for advanced registration is Friday, May 2. More information is available at http://www.rice.edu/jcdl03/tutorials.html, and one may register by visiting http://www.rice.edu/jcdl03/registration.html. * Introduction to Georeferencing in Digital Libraries Presenters: Linda Hill & Michael Freeston, University of California, Santa Barbara This tutorial covers the broad scope of georeferencing, including an overview of types of georeferenced objects and their characteristics; fundamental concepts of geospatial referencing; georeferencing structures of metadata standards (MARC, FGDC, Dublin Core, and more); gazetteers and their role in translating between textual and geospatial location referencing; supporting database architectures; and geospatial matching in information retrieval. In the process, the major information management standards for geospatial description, retrieval, interoperability, and information exchange will be identified. The tutorial is based on the experience of the presenters with the Alexandria Digital Library (ADL) Project at the University of California, Santa Barbara, but is not intended to be about the ADL itself but rather about the broader principles and practices of georeferencing in digital libraries. * How to Build a Geospatial Digital Library Presenters: Gregory Jane, Rudolf Nottrott, James Frew, & Catherine Masi, University of California, Santa Barbara This tutorial will be of interest to individuals or institutions with geospatial digital content which they would like to publish for structured search and retrieval over the Web. The tutorial is based on software developed by the Alexandria Digital Library Project (ADL), which facilitates the creation and management of distributed digital library collections. ADL collections can operate stand-alone for use by individual users, or optionally and seamlessly switch into a distributed mode for web-based information sharing and publication. Geospatial collections are typically heterogeneous in content and can span items as diverse as maps, historical photographs, field data, remotely sensed images or archeological data. The ADL software allows structured search and retrieval on such heterogeneous data collections, combining the simplicity of Dublin Core with the specificity of a full Boolean query language. The aim of the tutorial is to familiarize participants with the overall technology and with the specific procedures and software involved in setting up a stand-alone or distributed ADL node. As a case study, we will focus on a collection of USGS Digital Raster Graphics (DRG) maps. However, the technology we present is much more general: it can be applied to collections of any georeferenced library objects and, further, to collections of any objects to which a structured discovery technique can be applied. Based on Open Source components and open protocol standards (including Java,Tomcat, XML, JDBC, SQL), the ADL software is freely available and can be installed on all common software and hardware platforms.
