Given recent developments in the fields of GIS data modelling, spatial data representation and storage in spatial databases, together with wireless Internet communications, it is becoming more obvious that the requirements for developing a real time road traffic information system are being met. This paper focuses on building a data model for traffic representation with support from the current...

The availability of reliable spatial information is often a prerequisite for rapid decision making in health-, and emergency management. Meanwhile, there are many variations of “Geographical Information Systems” (GIS) on the market, ranging from Desktop-GIS and Internet-based GI-services to various kinds of mobile applications, the latter often localizing themselves via the GPS. The different f...

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...

The application of GIS has become fundamental in environmental studies since it allows the integration of heterogeneous data. Several applications of the GRASS GIS where the use of different data types leads to the realization of environmental models are presented. The GRASS GIS has been used to develop and test forest fire risk models combining several morphologic, vegetational and anthropic f...

The study presents an attempt to correlate the spatial distribution of damages and the ground deformation measure by SAR interferometric stacking technique in the case of Athens 7-9-99 earthquake. Damage maps were created for building collapsed and affected areas, built in a GIS environment. The location of the collapsed building was identified using a portable GPS resever and introduced as poi...

Mobile-messaging technology is evolving rapidly to provide multiple services and applications for Mobile subscribers. Mobile marketing and advertising applications deliver promotional information to consumers, based on their preferences and location. This paper examines the use of Promotionmessage in Product Advertising. In this paper, we present a context based location sensitive mobile applic...

Global Positioning System (GPS) is a worldwide satellite system that provides navigation, positioning, and timing for both military and civilian applications. GPS based time reference provides inexpensive but highly-accurate timing and synchronization capability and meets requirements in power system fault location, monitoring, and control. In the present era of restructuring and modernization ...

BACKGROUND Despite the demonstrated utility of GIS for health applications, there are perceived problems in low resource settings: GIS software can be expensive and complex; input data are often of low quality. This study aimed to test the appropriateness of new, inexpensive and simple GIS tools in poorly resourced areas of a developing country. GIS applications were trialled in pilot studies b...

The world of GIS is always in development, and this fact is particularly true for Open Source GIS. Among the GIS software, in the last years GRASS GIS has known wide popularity as it is well documented by the recent GRASS Users conferences, both at national and international levels and the incoming ones. The creativity and fantasy of the researchers together with the freedom of the source code ...
