Geospatial technologies like Remote Sensing and Geographical Information Systems (GIS) have been widely used in land resources survey and environmental monitoring. Assessment and monitoring of natural resources like land, soil, water and vegetation and socio-economic conditions and integrating them in a spatial information platform like GIS will facilitate the effective management of land resou...

Since 1996 GRASS is used in GIS classes at the Dipartimento di Ingegneria Civile ed Ambientale of the Università di Trento. This paper describes the potential of this GIS, with freely available code, in Geographical Information Systems education, both for university courses and professional training. The use of GRASS offers several advantages: the software is accessible without licensing worrie...

Today information systems play key role in new century, geographical information system (GIS) as a special class of information system. Now we are moving wired to wireless network, that is mobile environment shown in fig2 (any where any time and any thing computing), plays key role in this new century. In this application mobile GIS, which will be a network environment, is proposed, which can p...

Advanced Traveler [r~format~on Systems (ATIS) under the intelligent Vehicle Highway Systems (IVHS) context require efficient information retrieval and updating in a dynamic environment and at different geographical scales. Some problems in ATIS can be solved based on the functionalities provided by GIS systems. However, extra requirements such as realtime response are not readily met in existin...

GIS technology is credited with substantially improving police crime analysis and related resource allocation. Although GIS has been said to be an efficient and effective technology in policing, limited empirical assessment has been conducted. An examination of functions and a review of the literature suggests four major applications of GIS in policing: computerized crime mapping/crime analysis...

Introduction Since its origin in the late 1980’s, the development of geographical information science and of geographical information systems (GIS), the toolset enabling to conduct this type of research, has now reached the necessary maturity to be considered a main stream application: GIS evolved from the status of ‘a promising tool’ to the status of ‘a tool achieving its promises’. To maintai...

Introduction Technology that combines traditional manipulations with databases and complete visualization of geographic (spatial) analysis employing maps has been developed in order to explore the possibilities for Geographical Information Systems (GIS) to be used in sanitary and epidemiological surveillance system based on the analysis of morbidity and identification of influence of hazardous ...

BACKGROUND Treatment variation in prostate cancer is common, and it is driven by clinical and clinician factors, patient preferences, availability of resources, and access to physicians and treating facilities. Most research on treatment disparities in men with prostate cancer has focused on race and socioeconomic factors. However, the geography of disparities - capturing racial and socioeconom...
