The National Geospatial Digital Archive (NGDA) is one of eight initial projects funded by the Library of Congress’s National Digital Information Infrastructure and Preservation Program (NDIIPP). The project’s overarching goal is to answer the question: How can we preserve geospatial data on a national scale and make it available to future generations? This paper summarizes the project’s work in...

This paper presents research in Geographic Information Systems interoperability. Also, paper describes our work in development, introduces interoperability framework called GeoNis, which uses proposed technologies to perform integration task between GIS applications and legacy data sources over the Internet. Our approach provides integration of distributed GIS data sources and legacy informatio...

Coastal management and decision-making requires timely and accurate multidimensional geospatial data that often reside in government agencies, organizations, and institutions on various levels. Integration of such data involves research on the spatial and temporal characteristics of coastal geospatial information, interoperability of spatial databases and tools, and distributed and mobile techn...

Marketing information systems (MKIS) are decision support systems targeted at marketing-specific decisions. One of the most widely disseminated MKIS models divides the marketing decision universe into four domains and links these domains to each other and to other marketing activities. Unfortunately, there is little guidance on the construction of specific MKIS targeted at problems in these dom...

There is a growing need for web-based geographic information systems for easy and fast dissemination, sharing, displaying and processing of spatial information. The tremendous growth in the use of web and open-source geospatial resources has sparked development of web-based spatial applications to address multidisciplinary issues with spatial dimensions. This paper presents the integration of o...

Both Geographic Information Systems and Information Retrieval have been very active research fields in the last decades. Lately, a new research field called Geographic Information Retrieval has appeared from the intersection of these two fields. The main goal of this field is to define index structures and techniques to efficiently store and retrieve documents using both the text and the geogra...

Spatial decision support systems (SDSS) are decision support tools which have been used widely in addressing complicated issues involving a spatial component. The use of SDSS has increased greatly over the last few decades especially in fields such as planning, natural resources management, and environmental science. Traditionally, SDSS have been developed with Geographic Information Systems (G...

Geospatial applications are becoming indispensible part of information systems, they provides detailed information’s regarding the attribute data of spatial objects in real world. Due to the rapid technological developments in web based geographical information systems, the uses of web based geospatial application varies from Geotagging to Geolocation capabilities. Therefore, effective utilizat...

The "spilling-out" represented by Vespucci was not of artistic achievement but of an approach to the investigation of the Earth. It was concerned, as was all exploration at the time, primarily with the Earth's form, of how the world looked: its capes and bays, its human and natural resources. The exploration effort to which Vespucci contributed was a painfully slow process, and it was not until...

This paper addresses data modeling problems inherent in the use of geographic information systems (GIS) that are not adequately covered by traditional modeling techniques. GIS technology has only recently begun to be used for traditional system development by large numbers of organizations and there are few procedures for modeling GIS data and applications in a business context. This circumstan...
