The aim of this paper is to develop a conceptual framework for studying the use of geo-information and associated technology in government. We first review how geo-information, geo-information technology and people—notions central to geo-information use—are conceptualized in the literature and show that authors view these notions through two contrasting lenses, a market and a polis lens. We the...

Gross primary productivity is one of the most important factors in the carbon cycle of terrestrial ecosystems. With global warming increase, the frequent drought events and the specific response of regional vegetation to these changes, it is essential to identify and quantify the relationships between climatic and GPP data in arid region. In this study, the responses of gross primary productivi...

A geometric graph G is a simple graph G together with a straight line drawing of G in the plane with the vertices in general position. Two geometric realizations of a simple graph are geo-isomorphic if there is a vertex bijection between them that preserves vertex adjacencies and non-adjacencies, as well as edge crossings and non-crossings. A natural extension of graph homomorphisms, geo-homomo...

Shoreline mapping and shoreline change detection are critical in many coastal zone applications. This paper presents results of the semi-automatic mapping of a coastal area of Lake Erie using 4-meter resolution multispectral (XS) and 1-meter resolution panchromatic (Pan) IKONOS Geo stereo images. An overview of the geometric processing of IKONOS imagery is presented. Then, the latest results of...

UNLABELLED The NCBI Gene Expression Omnibus (GEO) represents the largest public repository of microarray data. However, finding data in GEO can be challenging. We have developed GEOmetadb in an attempt to make querying the GEO metadata both easier and more powerful. All GEO metadata records as well as the relationships between them are parsed and stored in a local MySQL database. A powerful, fl...

A decade ago, the Gene Expression Omnibus (GEO) database was established at the National Center for Biotechnology Information (NCBI). The original objective of GEO was to serve as a public repository for high-throughput gene expression data generated mostly by microarray technology. However, the research community quickly applied microarrays to non-gene-expression studies, including examination...

The protected GEO region is defined by boundaries in inclination (-15° ... +15°) and orbit radius (± 200 km with respect to true GEO height). There are nearly 390 operational satellites with orbits inside of this zone. In addition, there are nearly 280 officially catalogued objects with orbits completely inside of the protected zone, and nearly 180 catalogued GEO satellites with orbits crossing...
