In recent years, Remote Sensing and Geographical Information System (GIS) technologies has been the object of considerable interest to all bodies concerned with space and in particular emergency services and disaster management. In this paper we, address the issues regarding contemporary works on role of GIS in disaster Management. This paper is a review of some interesting and milestone resear...

The progress of remote sensing (RS), geographic information system (GIS) and global position system (GPS) in China since the early 1980s.The first section introduces the applications of remote sensing to environmental monitoring and resources investigation in tourism. The second section focuses on further analysis of the applications of geographic information system from the point of view of vi...

This paper puts forward a novel method of automatically generating elements which is necessary for building sharing ontology database and studies the uncertainty problems. A concept called sharing ontology is proposed which is defined as a bridge of all kinds of spatial information systems involving domain spatial data acquiring, updating, transferring, storing, processing, analyzing, informati...

Spatial Database is a collection of spatially referenced data that acts as a model of reality. Geographical Information System includes spatial data which is either in raster or vector form and data derived from remote sensors are increasingly utilized as source for GIS. Spatial data is the core part of the Geographical Information System. Data mining techniques are studied to discover knowledg...

In the past several decades, Lagos Metropolis emerged as one of the fastesturbanizing cities in the West African Sub-region. In the absence of a regular use ofgeospatial information management systems, limited effort had been made to keep track ofchanges in the natural environment in the rapidly growing city for policy making in landadministration. The ubiquitous energy radiated by the rapid ur...

To create the final spatial information and analysis, flood hazard maps and land development priority maps and information, data for the flood events to 2009 in north of Iran were incorporated with using Geo-spatial Information System data of physiographic divisions, geologic divisions, land cover classification, elevation, drainage network, administrative districts and population density and e...

given the critical role played by urban green spaces and the emergence of remote sensing as avaluable natural resource management tool, this study sought to identify trends in green spaces within thecontext of south africa’s transition period (1990 - 2000). using the city of port elizabeth as a case study, threesets of landsat - 5 thematic mapper images (1990, 1995 and 2000) were geo-processed,...

Drought is one of the most threatened natural vulnerabilities that are initiated by reason of scarcity of rain in a specific region. By comparing with all other natural hazards, it is very tough to discover since it develops slowly and have massive effect on the society and environment. Hence, in many countries satellite based drought indications have been recommended for early identification. ...

This paper highlights the use of remote sensing technologies in disaster management. Impact of natural disasters on life, property and ability to predict them would be one of the main contributions of remote sensing technology. Involving remote sensing with GIS and web technology makes it an extremely powerful tool to identify indicators of potential disasters. Information sharing through Inter...
