The creation and management of geospatial data is always tedious requires huge budget, time and manual efforts. Therefore, the future of several important services including location-based services and disaster information system, which need geospatial data remains a matter of concern. Expert geoportal system (EGPS) is a tool based on a sophisticated approach for providing diverse geospatial se...

Agent-based approaches have not yet been widely applied to highly complex, data intensive,large-scale information processing systems such as are found in the domain of imagery & geospatial computing. Such systems combine diverse and distributed types of imagery and geospatial data, and require collaboration from multiple experts and processing components. This paper gives a description of the d...

Cornell University Geospatial Information Repository, CUGIR, is a Web-based repository providing free access to geospatial data and metadata for New York State. Access is enhanced by transforming and re-purposing geospatial (FGDC) metadata into DC-RDF, Metadata Object Description Schema (MODS) and MARC 21 that is rendered in XML, HTML, SGML, and ASCII text on-thefly. Although libraries today ar...

While free and open source software becomes increasingly important in geospatial research and industry, open science perspectives are generally less reflected in universities’ educational programs. We present an example of how free and open source software can be incorporated into geospatial education to promote open and reproducible science. Since 2008 graduate students at North Carolina State...

Multi-criteria shortest path problems (MSPP) are called as NP-Hard. For MSPPs, a unique solution for optimizing all the criteria simultaneously will rarely exist in reality. Algorithmic and approximation schemes are available to solve these problems; however, the complexity of these approaches often prohibits their implementation on real-world applications. This paper describes the development ...
