Data in Geo Information Systems (GIS) is used for map services and various applications. Thus, quality assessment on a regular basis is required to keep the data up-to-date. In this paper we focus on one key reasons for updates: incorrect object borders. State of the art systems semi-automatically analyse up-to-date satellite image data to narrow down areas that have to be considered for GIS up...

Geographic information systems (GIS), global positioning systems and remote sensing have been increasingly used in public health settings since the 1990s, but application of these methods in humanitarian emergencies has been less documented. Recent areas of application of GIS methods in humanitarian emergencies include hazard, vulnerability, and risk assessments; rapid assessment and survey met...

This paper will describe the development and evolution of GIS to support environmental quality monitoring and hazards mitigation activities in two citizen-based water watch movements: Alabama Water Watch and Nucleo Pro Tiete in Sao Paulo, Brazil. In both cases, citizen volunteers concerned with creating baseline databases for local watershed areas formed as a result of severe problems in local ...

The ecological construction for demonstration area is an idealized model for the establishment of rural sustainable development in the countyscale. This paper presents a GIS-based evaluation system of ecological construction for demonstration area. It includes an index system with the 4 secondary indices and 24 factor indices, and a method of ecological construction for demonstration area utili...

The recent advances in geo-informatics have been opening new opportunities in earthquake early warning and emergency management issues. In the last years, the geo-scientific community has recognized the added value of a geo-analytic approach in complex decision making processes for critical situations due to disastrous natural events such as earthquakes. In fact, recently, GIS-based solutions a...

GIS software has different useful tools that can be used for sites, demographic and competitive analysis. These tools enable retail and market researchers to find solutions related to many retail planning issues. The aim of this paper is to use Geographical Information Systems (GIS) for retail location assessment of two retail centers called Al-Dawly and Al-Mahmal centers located at Jeddah city...

There is an increasing interest in agent-oriented technology, spanning applications as diverse as information retrieval, user interface design and network management. Application of intelligent agents in the GIS environment is actively being explored. Many different types of agents are being employed to improve usability of GIS software as well as users access to geospatial data and services av...
