Earthquake disaster monitoring and evaluation based on spatial information technology

Space information technology which includes the geographic information system GIS,remote sensing RS,global navigation satellite system GNSS and digital earth platform,it is an earth space information science.With the development of computer and space on earth observation technology,the space information technology has been applied gradually in earthquake resistance and disaster mitigation fields.This article through the actual examples respectively analyzed the current earthquake disaster monitoring and evaluation method which is based on GIS and RS technology.Sums up the advantages and the existing problems,and with digital earth platform visually shows the effect of comprehensive multi-source data spatial information technology used in earthquake damage assessment.
