Locating usable spatial data is essential for the application and use of Geographic Information Systems (GIS). GIS data collection development constitutes a core element of GIS services within academic libraries. Managers of geospatial resources require a fundamental understanding of the nature and use of GIS data. In the creation of a GIS collection development policy, library professionals sh...

Understanding the factors limiting migratory behaviour is fundamental to conservation of diadromous fish. Applications of indices of habitat suitability are problematic for diadromous fish because fish presence and abundance in relation to habitat quality are confounded by barriers to fish migration. An alternative approach is to assess diadromous fish distributions in proportion to distance in...

OBJECTIVE To compare the epidemiology of pediatric pedestrian injury in Jacksonville, FL to national trends, to analyze geographic distribution of these injuries, and to analyze pedestrian injury severity trends over time. METHODS Hospital emergency department and trauma registry data were analyzed for calendar year 2002 to define the incidence by age of vehicular pedestrian injury (Classific...

Abstract Indian coastal regions have often been affected by frequent climate-induced natural disasters such as cyclones, floods, droughts and other related hazards in recent decades. Existing literature was not sufficient to fully understand these event trends from diverse perspectives a systematised manner at current scenarios. Therefore, systematic approach has employed assess the climate cha...

The Adriatic Sea is a semi-enclosed sea of the European side of the Mediterranean, covering 138 595 km2 and containing 35 000 km3 of sea water (LUŠIĆ & KOS, 2006). It exchanges its waters with the greater Mediterranean through the Otranto Strait at an approximate rate of 3.3 years (FRANIĆ, 2005), although turnover time varies from 1-5 years when determined with A set of spaceborne synthetic ape...

Despite the fact that all geospatial data are, at different levels, imperfect, GIS technologies do not offer much support to GIS users to make them aware of the imperfections and potential limitations in the use of these data. Recent research progresses have been made towards the design of GIS that would take into account data quality. These approaches extend typical GIS functionalities to mana...

Without a department of geography, Harvard University established the Center for Geographic Analysis (CGA) in 2006 to support research and teaching of all disciplines across the University with emerging geospatial technologies. In the past four and a half years, CGA built an institutional service infrastructure and unleashed an increasing demand on geographic analysis in many fields. CGA servic...

When facing local environmental issues, maps are a very effective tool. They can help in collecting facts about an area, bring issues to the table, allow for comparison between areas, act as a tool of communication with local decision makers, and identify key issues for action. While the maps on their own do not alter the power relationships within which communities live their lives, many studi...

Safety and emergency response are being given greater importance while planning infrastructure and transportation projects. This is particularly so, when transporting hazardous materials HAZMAT within a heavily urbanized area such as Singapore. The number and location of fire stations significantly influence the efficiency of emergency response during fire accidents. This paper presents an appr...

Geographical semantic representation, which aims at enhancing geospatial data model and facilitating information sharing and exchange, has been a hot topic in the realm of geographic information science. The research summarized here is to advance a geographical semantic representation framework to support geo-collaboration, focusing on how to take full advantage of Ontology and Web Services tec...
