The post-disaster investigation also produces the important reference information for disaster recovery and reconstruction. How to perform the investigation and damage assessment rapidly and automatically will be the most important study issue. Recently, the development of platform with direct positioning and multi-sensor (also name mobile mapping system, MSS) will provide the best tools for disaster investigation. In this study, the possible applications for environment monitoring and disaster management using MMS in Taiwan will be demonstrated firstly. The main study topics consist of how to get the disaster information using MSS and the estimation of the influence of the positioning errors from the MSS. Then the procedures for the scale recognition and damage assessment for earthquake and landslide hazards will be illustrated. The main research topics include the positioning of the multi-source and multi-temporal images and laser scanner data from the MMS, the automatic registration between the positioned images and the 2D or 3D geospatial database, and change detection for damage assessment. Finally, an information system based on the OGC data standards and web services (OWS) will be developed to store and display the resulted data and 3D information captured from the MSS. The corresponding database will include the multi-source multi-temporal images, laser scanner data, the reconstructed building models and disaster geo-informations.移動式測圖系統變異偵測災害管理網路服務Mobile Mapping System (MSS)Change DetectionDisaster ManagementWeb Services
