Visualization damage evaluation system research of structure in subsidence area based on GIS

Mining subsidence lead to deform of the earth´s surface,which result in different destroy of structure on the earth´s surface.Combine damage evaluation of structure in subsidence area with GIS make the damage evaluation scientific,efficient,visual. Damage evaluation system of structure based on ArcGIS 9,which is integrated development system, applies object-oriented visualization programming language named Visual Basic 6.0,uses Microsoft Access 2003 as bottom database.The system by means of the powerful spatial analysis function of ArcGIS 9,enhances the computing power through second-round developing.Damage evaluation system of structure based on ArcGIS integrates spatial analysis and evaluation calculation together, carrys out visualization damage evaluation.
