Abstract

This paper describes the development of a digital spatial library based on mosaics of digital orthophotos, called Interactive Portugal, that will enable users both to retrieve geospatial information existing in the Portuguese National System for Geographic Information World Wide Web server, and to develop local databases connected to the main system. A set of navigation, interaction, and visualization tools are proposed and discussed. They include sketching, dynamic sketching, and navigation capabilities over the digital orthophotos mosaics. Main applications of this digital spatial library are pointed out and discussed, namely for education, professional, and tourism markets. Future developments are considered. These developments are related to user reactions, technological advancements, and projects that also aim at delivering and exploring digital imagery on the World Wide Web. Future capabilities for site selection and change detection are also considered.
