چکیده
The Alexandria Digital Library (ADL) Project has developed digital library services and collections to support the organization, access, and use of collections of information with the use of geospatial reference [1]. The Project's operational component is the Alexandria Digital Library (ADL), developed under Phase I of NSF's First Digital Libraries Initiative and now operational as part of the California Digital Library (CDL). The Project's research and development component is the Alexandria Digital Earth Prototype (ADEPT) [2], supported under NSF's Second Digital Libraries Initiative.

Visual Explorations for the Alexandria Digital Earth Prototype
The Alexandria Digital Earth Prototype project addresses issues of access, browsing, delivery and understanding of georeferenced library items. Two visualization approaches, both of which address these issues in different ways, are under development: interfaces between some existing digital earth systems and the digital library, and spatial but nongeoreferenced information space experimentation...

متن کاملDAR: A Digital Assets Repository for Library Collections
The Digital Assets Repository (DAR) is a system developed at the Bibliotheca Alexandrina, the Library of Alexandria, to create and maintain the digital library collections. The system introduces a data model capable of associating the metadata of different types of resources with the content such that searching and retrieval can be done efficiently. The system automates the digitization process...
متن کاملBrowsing large satellite and aerial photographs
Image content based retrieval in the Alexandria digital library project has focussed on texture and color features for querying the database. A robust texture feature extraction algorithm and a fast segmentation scheme have been developed. The texture features are computed by filtering the image with a bank of Gabor filters. This is followed by a clustering scheme to create a texture based feat...
